A review on photocatalytic systems capable of synchronously utilizing photogenerated electrons and holes

摘要

With the continuous progress and development of current industrial civilization,energy crisis and envi-ronmental pollution are serious problems that threaten human beings need to be solved.Photocatalytic technolo-gies that can use clean solar light energy to manufacture clean H2 fuel and high value chemicals provide a feasibility to solve the above problem.However,traditional photo-catalytic water splitting mainly focused on the utilization of photogenerated electrons to produce H_(2) which leads to the waste of the holes.It is vital to develop photocatalysts capable of synchronously utilizing photogenerated elec-trons and holes for the future practical application.In this paper,the latest progress of photocatalytic system with collaborative photooxidation-reduction application has been summarized,and water splitting for H_(2) production combining different organic synchronous reaction process has been clarified.Finally,the prospect of photocatalysts capable of synchronously utilizing photogenerated elec-trons and holes are proposed.
