摘要
The exploitation and utilization of fossil energy has caused serious problems such as environmental pollution and climate change.It is imperative to develop renewable and clean energy sources.Hydrogen energy is recognized as one of the most superior energy carriers in the world because of its characteristics of high energy density,convenient storage and transportation,and pollution-free energy conversion products.Many energy sources could be converted to hydrogen energy,of which,solar energy is abundant and clean.Therefore,nowadays,the efficient conversion of solar energy to hydrogen energy has become one of the hot topics in the renewable energy area.Photocatalysis based on the principles of Honda-Fujishima effect provides an opportunity to address the above challenge.The recent years have witnessed the rapid growth of photocatalytic hydrogen production from photocatalysis and photoelectrocatalysis via solar light.
