Rational Design of Hybrid Nanostructures for Advanced Photocatalysis 本文综述了纳米催化剂（金属和多金属纳米颗粒、金属-半导体杂化结构、氧化物纳米颗粒）对各种催化反应的研究进展。本文参考文献149篇，发表Advanced energy materials。 Nanocatalysis has been a growing fi eld over the past few decades with signifi - cant developments in understanding the surface properties of nanocatalysts. With recent advances in synthetic methods, size, shape and composition of the nanoparticles can be controlled in a well defi ned manner which facilitates achieving selective reaction products in multipath reactions. Nanoparticles with specifi c exposed crystal facets can have different reactivity than other facets for reaction intermediates, which favours selective pathways during the course of reaction. Heterogeneous catalysts have been studied extensively; nano-sized metal particles are absorbed on mesoporus supports, facilitating access to the large surface area of the nanoparticles and hence exposure of more catalytic sites. Photocatalysis is attractive area of catalysis, in which photoinduced charge carriers are used for a variety of catalytic applications. More interestingly, clean and renewable liquid fuels energy sources such as hydrogen and methyl alcohol can be generated using photocatalysts through water splitting and CO 2 reduction, respectively. Herein, we highlight the progress of nanocatalysis through metal, bimetallic nanoparticle, metalsemiconductor hybrid nanostructures and oxide nanoparticles for various reactions. |
