Construction of kinked heteronanorods modified by metal nanoparticles with enhanced catalytic performance

Abstract

Unique kinked semiconductor–metal Au–Ag₂S–ZnS and Au–Ag₂S–ZnS–Au heteronanorods have been synthesized for the first time by a seed-mediated growth method. A plausible mechanism for the formation of kinked heteronanorods is proposed. The catalytic activity of such novel kinked semiconductor–metal heteronanorods with selective deposition and uniform morphology is also investigated via a model reaction based on the reduction of 4-nitrophenol by NaBH₄.
