Introduction to Heterostructured Nanoparticles

What is/are Heterostructured Nanoparticles?

Heterostructured Nanoparticles - Herein, we develop a feasible and delicate synthesis of Fe/Fe3C/Fe2O3 hollow heterostructured nanoparticles in situ immobilized on highly graphitic nitrogen-doped carbon nanotubes (referred to as Fe/Fe3C/Fe2O3@N-CNTs hereafter) via a simple hydrogel-bridged pyrolysis strategy. ^[1] In this work, nickel–iron based sulfides were synthesized through a one-pot hydrothermal approach which is characterized as defect-rich Ni9S8/Fe5Ni4S8 heterostructured nanoparticles. ^[2] Herein, we report a novel tri-functional electrocatalyst, N,P co-doped carbon nanotubes confined WN-Ni Mott-Schottky heterostructured nanoparticles (WN-Ni@N,P-CNT) via one-pot pyrolysis. ^[3] Bimetallic high-index faceted heterostructured nanoparticles represent a new class of high-performance nanocatalysts. ^[4] Despite remarkable facileness and potential in forming a wide variety of heterostructured nanoparticles with extraordinary compositional and structural complexity, one-pot synthesis of multicomponent heterostructures is largely limited by the lack of fundamental mechanistic understanding, designing principles, and well-established, generally applicable chemical methods. ^[5] The combination of various the nanoscale characterizations and theoretical modeling ascertain that the in situ generated Co/MnO heterostructured nanoparticles (NPs) not only create many metal defects and oxygen vacancies, but also enhance the Co-MnO interaction at Co/MnO heterointerface, which promote CO2 adsorption and facilitate CO2 activation. ^[6] 959 Design principles predict the number and types of interfaces in polyelemental heterostructured nanoparticles. ^[7] Here, we examined the incorporation of zinc and gallium ions in InP clusters and the use of the resultant doped clusters as single-source precursors to emissive heterostructured nanoparticles. ^[8] These plasmonic nanoparticles including heterostructured nanoparticles and composite nanostructures are prepared by direct synthesis and physical force- or biomolecule-mediated assembly, which hold tremendous potential for plasmon-mediated energy transfer, magnetic plasmonics, metamolecules, and nanobiotechnology. ^[9] Colloidal heterostructured nanoparticles that integrate multiple materials through direct solid–solid interfaces are desirable across a wide range of applications. ^[10] In this work, we report that the interparticle plasmonic coupling could be circumvented by first synthesizing Au/metal or nonmetal oxide heterostructured nanoparticles and then depositing them uniformly onto the substrates, leading to high reproducibility of the Raman signals. ^[11] W/W2C heterostructured nanoparticles encapsulated by N,P dual-doped carbon (W/W2C@NPC) fabricated by the carbonization of in situ polymerized polyaniline (PANI) and phosphotungstic acid require low overpotentials of 55 mV and 82 mV vs. ^[12]
