Introduction to Ruthenium Nanoparticles

What is/are Ruthenium Nanoparticles?

Ruthenium Nanoparticles - Ruthenium nanoparticles immobilized on amine-functionalized polymer-grafted silica act as active and stable catalysts for the hydrogenation of biomass-derived furfural acetone and related substrates. ^[1] Here, we demonstrate the hydrogenolysis of polyethylene into liquid alkanes under mild conditions using ruthenium nanoparticles supported on carbon (Ru/C). ^[2] In this research, the electrocatalytic activity of platinum-ruthenium nanoparticles on carbon nanotubes and carbon black in methanol oxidation reaction has been investigated. ^[3] Mono and bimetallic platinum–ruthenium nanoparticles have been generated on N-doped graphene (NH2-rGO) following an organometallic approach. ^[4] Evaluation of the catalyst showed that ruthenium nanoparticles (~ 2 nm) supported by titanium dioxide (TiO2) produced significant activity and selectivity for phenol HDO. ^[5] Ruthenium nanoparticles supported on CoNi-LDO with an urchin-like structure exhibit superior catalytic properties toward AB hydrolysis for hydrogen production, which is confirmed by theoretical simulation. ^[6] The formation of ruthenium nanoparticles in magnetic Fe3O4 has been confirmed by TEM, TEM–EDX and XPS studies. ^[7] A series of catalysts with ruthenium nanoparticles (NPs) loaded on the binary oxide TS (TiO2-SiO2) support were prepared by facile sol-gel method for benzene selective hydrogenation. ^[8] The high selectivity of Ru/HBEA (Si/Al = 25) can be explained by the presence of Bronsted / Lewis acid centers with medium strength in the proximity of ruthenium nanoparticles. ^[9] rGO cathodes with well-dispersed α-MnO2 nanowires and ruthenium nanoparticles were successfully synthesized and shown to dramatically increase (decrease) oxygen reduction (evolution) reactions. ^[10] In this work, ruthenium nanoparticles (RuNPs) are electrochemically synthesized over cathodically treated stainless-steel mesh (CSS) by applying the cathodic current of −15 mA/cm2 using ruthenium chloride and deep eutectic mixture consists of choline chloride/urea as electrolyte. ^[11] Here, Ni2P nanosheets arrays decorated with ruthenium nanoparticles are grown in situ on a carbon cloth substrate (denoted as Ru-Ni2P/CC) via surface modification engineering, exhibiting good electrical conductivity and superior hydrophilicity. ^[12] The analytical data received from the above analysis were found in good correlation to each other and confirm the uniform distribution of ruthenium nanoparticles over the surface of the silica–carbon coated magnetic cobalt system. ^[13] A new enzyme-free electrochemiluminescence (ECL) pesticide sensor was fabricated based on ternary nanocomposite of ruthenium nanoparticles/silver nanoparticles/graphene oxide on the surface of glassy carbon electrode for ultratrace determination of diazinon. ^[14] The influence of the preparation procedure on the morphology of ruthenium nanoparticles selectively formed inside mesoporous aluminosilicate nanotubes was examined. ^[15] Herein, a novel nano-bionic sensor based on the superior catalytic activity of ruthenium nanoparticles (Ru NPs) has been fabricated for H2S quantification. ^[16] Here, we demonstrate new solvothermal synthesis methods with facile allotropism control for selectively obtaining hexagonal-close-packed (hcp) and face-centered cubic (fcc) ruthenium nanoparticles. ^[17] Ruthenium nanoparticles (Ru NPs) stabilized by bis-diphenylphosphinobutane (dppb) and surface-saturated with hydrogen have been exposed to gaseous 15NH3 and 13CO and studied using solid-state NMR and DFT calculations. ^[18] AMS detection is proposed here for the first-time using Ruthenium nanoparticles (Ru) and Safranin (Saf) as a modifier through carbon paste electrochemical sensor platform. ^[19] The aim of this study is to evaluate the control that such a photoassisted method can exert on the properties of ruthenium nanoparticles supported on TiO2 by means of the variation of the incident irradiance and hence of the photodeposition rate. ^[20] In our paper, a promising electrochemical sensing platform was fabricated with titanium carbide (Ti3C2Tx), poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), and ruthenium nanoparticles (RuNPs). ^[21]

reduced graphene oxide

Here, uniformly dispersed ruthenium nanoparticles anchored on nitrogen-doped reduced graphene oxide are prepared by using an in situ pyrolysis procedure as a bifunctional catalyst for lithium-oxygen batteries. ^[1] A new catalyst was prepared using sulfonated reduced graphene oxide support with a large surface area containing ruthenium nanoparticles (Ru@rGO-SO3H). ^[2]

Supported Ruthenium Nanoparticles

The present paper employs supported ruthenium nanoparticles alongside catalytic quantities of the radical initiator, which are proven to be capable of cyclooctene oxidation with green conditions, in the absence of solvent, with air as the main oxidant and without sacrificial reductant. ^[1] In this work, we reported a new catalyst consistent of graphene oxide (GO) – poly(N-vinyl-2-pyrrolidone) (PVP) hybrid supported ruthenium nanoparticles and called as Ru@GO-PVP. ^[2] Ceria supported ruthenium nanoparticles (Ru0/CeO2) are synthesized by impregnation of Ru3+ ions on CeO2 powders followed by sodium borohydride reduction of Ru3+/CeO2. ^[3]

Small Ruthenium Nanoparticles

Formation of stable carbides during CO bond dissociation on small ruthenium nanoparticles (RuNPs) is demonstrated, both by means of DFT calculations and by solid state 13C NMR techniques. ^[1] The as-prepared NC-Fe material was then modified with small ruthenium nanoparticles (Ru NPs), obtaining a Ru/NC-Fe catalyst for efficient catalytic hydrogen generation from ammonia borane (AB). ^[2] Calcination of ruthenium-impregnated UiO-66(Zr)-NH2 leads to formation of small ruthenium nanoparticles (. ^[3]

Containing Ruthenium Nanoparticles

Nanostructured 1 and 3% catalysts containing ruthenium nanoparticles supported on the initial and oxidized at different temperatures graphite-like carbon material Sibunit-4 prepared. ^[1] The purpose of this work is the design of metal-zeolite nanocomposite catalysts for Fischer–Tropsch synthesis, containing ruthenium nanoparticles, uniformly distributed in the hierarchical BEA zeolites. ^[2] A new catalyst was prepared using sulfonated reduced graphene oxide support with a large surface area containing ruthenium nanoparticles (Ru@rGO-SO3H). ^[3]

Dispersed Ruthenium Nanoparticles

Here, uniformly dispersed ruthenium nanoparticles anchored on nitrogen-doped reduced graphene oxide are prepared by using an in situ pyrolysis procedure as a bifunctional catalyst for lithium-oxygen batteries. ^[1] Herein, highly dispersed ruthenium nanoparticles entrapped in TiO2 nanotubes, labeled as Ru-in/TNT, were constructed and adopted for photo-thermal driven CO2 methanation. ^[2] In this work, the dispersed ruthenium nanoparticles are stabilized on hexagonal boron nitride (h-BN) via an adsorption-in situ reduction procedure. ^[3]

Mesoporou Ruthenium Nanoparticles

Here, we adopted a novel design that uses PEGylated hollow mesoporous ruthenium nanoparticles as a carrier to load the fluorescent anti-tumor complex ([Ru(bpy)2(tip)]2+, RBT) and a conjugate with bispecific antibodies (SS-Fc). ^[1] Mesoporous ruthenium nanoparticles (Ru NPs) were used as nanocarriers, loading prodrug ascorbic acid (AA) and encapsulated by hyaluronic acid (HA). ^[2]

ruthenium nanoparticles supported

Nanostructured 1 and 3% catalysts containing ruthenium nanoparticles supported on the initial and oxidized at different temperatures graphite-like carbon material Sibunit-4 prepared. ^[1] Here, we demonstrate the hydrogenolysis of polyethylene into liquid alkanes under mild conditions using ruthenium nanoparticles supported on carbon (Ru/C). ^[2] Previously, we identified ruthenium nanoparticles supported on carbon (Ru/C) as a highly active heterogeneous catalyst for the conversion of polyethylene into liquid and gaseous n-alkanes under mild conditions. ^[3] Ruthenium nanoparticles supported on CoNi-LDO with an urchin-like structure exhibit superior catalytic properties toward AB hydrolysis for hydrogen production, which is confirmed by theoretical simulation. ^[4] The aim of this study is to evaluate the control that such a photoassisted method can exert on the properties of ruthenium nanoparticles supported on TiO2 by means of the variation of the incident irradiance and hence of the photodeposition rate. ^[5] Catalytic hydrothermal gasification (HTG) of organic matter over ruthenium nanoparticles supported on high surface area carbon poses the best catalytic system up to date for selective production of methane. ^[6]

ruthenium nanoparticles deposited

This study demonstrates a crystal facet-dependent catalytic reduction of CO2 to CH4 on ruthenium nanoparticles deposited over TiO2 nanocrystal with exposed (001) and (101) facets. ^[1] A hybrid catalyst is synthesized using ruthenium nanoparticles deposited on a nanospherical mesoporous polymer. ^[2]

ruthenium nanoparticles immobilized

Ruthenium nanoparticles immobilized on amine-functionalized polymer-grafted silica act as active and stable catalysts for the hydrogenation of biomass-derived furfural acetone and related substrates. ^[1] Catalytic hydrogenolysis of diaryl ethers is achieved by using ruthenium nanoparticles immobilized on an acidic supported ionic liquid phase (Ru@SILP-SO3H) as a multifunctional catalyst. ^[2]
