What is/are Ultrafine Ru?

Ultrafine Ru - An efficient HER catalyst of ultrafine Ru nanoclusters supported on N/S-doped macroporous hollow carbon spheres is developed. ^[1] A double-shell structured carbon catalyst (DSC) is designed with selectively locating ultrafine Ru NPs only on inner carbon shell, specifically, different N species on the external carbon shell. ^[2] Ultrafine Ru nanoparticles ( 99% 4,4’-diaminodicyclohexylmethane selectivity, corresponding to a reaction activity of 35. ^[3] Herein, we report a facile methodology for fabricating the hierarchical porous nanostructures riveted with ultrafine Ru nanoclusters as high-performance nanoreactors for overall water splitting from MOF precursors. ^[4] In this study, we designed and constructed a 0D ultrafine ruthenium (U-Ru) quantum dot decorated 3D porous g-C3N4 (3DpCN) nanohybrid (U-Ru/3DpCN) for photocatalytic hydrogen evolution, in which the U-Ru quantum dots act as cocatalysts accelerating the surface proton reduction reaction, and the 3D porous architecture assembled by 2D ultrathin nanosheets inherits a short charge diffusion distance and has a large specific surface area. ^[5] Synergism of ultrafine RuCo alloy nanoparticles on graphite carbon nitride were achieved for an efficient ammonia borane hydrolysis. ^[6] Herein, we have successfully synthesized a nitrogen-doped carbon (NC) coated ultrafine ruthenium phosphides (RuP2) nanoparticles catalyst with a facile method. ^[7] Herein, a facile top-down strategy is presented to synthesize ultrafine Ru nanoparticles confined in three-dimensional (3D) porous nitrogen-doped carbon nanosheets (Ru/3DNCN). ^[8] Ultrafine Ru nanoparticles (RuNPs) supported on N-doped exfoliated Ni-Fe layered double hydroxide (LDH) nanosheets (Ru/Ni-Fe LDH) are prepared by nitrogen glow discharge plasma without adding any chemical stabilizers or reducing agents. ^[9] In this study, we fabricated ultrafine RuO2 nanoparticles on carbon black to form a strawberry-like RuO2/C hybrid, using by a solid-phase grinding and subsequent low-temperature annealing. ^[10] Carbon-supported ultrafine Ru nanoparticles with 0. ^[11] Herein, an ordered macroporous superstructure of N-doped nanoporous carbon anchored with the ultrafine Ru nanoclusters as electrocatalytic micro/nanoreactors is developed via the thermal pyrolysis of ordered macroporous single crystals of ZIF-8 accommodating Ru(III) ions. ^[12] Here, we not only improved the yield of GeP5 nanosheets by a liquid nitrogen-assisted liquid-phase exfoliation technique but also constructed the GeP5@RuO2 nanocomposites with the 0D/2D heterostructure by in situ introduction of ultrafine RuO2 nanoparticles on highly conductive GeP5 nanosheets using a simple hydrothermal synthesis method, and then applying it to micro-supercapacitors (MSCs) as electrode materials through a mask-assisted vacuum filtration technique. ^[13] Herein, ultrafine Ru/Ni2P nanoparticles (NPs) with quantum dot interfaces encapsulated in N,P-codoped hollow carbon nanospheres (Ru/Ni2P@NPC) are prepared through a two-step process including carbonization and subsequent phosphorization. ^[14] The combination of ultrafine Ru nanoparticles and hollow spherical support endows the resultant Ru/GHSs an extraordinary catalytic performance with a low overpotential of 24. ^[15] For the first time, we demonstrate a transient, in situ thermal shock method combined with a three-dimensional cross-linked structure derived from CO2 gasification to produce a high dispersion of ultrafine Ru nanoparticles on activated carbon nanofibers to serve as an efficient cathode in Li–CO2 batteries. ^[16] In addition, ultrafine Ru nanoclusters were successfully encapsulated in CC3-R with high dispersion via impregnation and subsequent reduction, affording Ru nanoclusters with a precisely controlled size of ∼0. ^[17] Here we report the application of ultrafine ruthenium on boron carbide (Ru/B4C) with highly efficient multifunctional activities as carbon-free oxygen electrodes for Li O2 batteries. ^[18] Herein, in this work, ultrafine Ru nanoparticle (NP) decorated WSe2 nanosheets have been successfully prepared by a colloidal synthetic approach. ^[19] As a proof of concept, the synthesis of ultrafine Ru nanoparticles (≈2. ^[20] The ultrafine Ru particles displayed the excellent activity for the hydrogenation of olefins, arenes, phenol derivatives and heteroarenes in aqueous phase. ^[21] Here a facile one-step pyrolysis strategy is reported to synthesize ultrafine Ru nanocrystals uniformly dispersed on N-doped carbon (Ru/NC) as electrocatalysts for the alkaline HER. ^[22]
