Ni–MoO₂ heterostructure encapsulated in mesoporous silica microtubes: a structured hydrogenation catalyst with enhanced activity for reduction of 4-nitrophenol

Abstract

Metallic Ni catalysts often suffer from serious aggregation and poor stability during the process of catalysis. In this work, core−shell nanostructures with nanosized MoO2-Ni nanoparticles (NPs) and mesoporous SiO2(mSiO2) shells...
