In situ assembly of well-dispersed Ni nanoparticles on silica nanotubes and excellent catalytic activity in 4-nitrophenol reduction

Abstract

Ni nanoparticle/silica nanotube composites with small particle size, good dispersion and high loading amount of Ni NPs was synthesized using an in situ thermal decomposition and reduction strategy. The composite exhibited high catalytic activity and good stability in 4-NP reduction.
