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. |
