Environmental pollution and energy shortage have emerged as two of the major environmental problems facing today,which have become the focus of global attention.If the management of environmental pollutants can be accompanied by the development of new clean and renewable sources of energy,it is possible to synergistically tackle the two major problems of pollution and energy,providing a useful solution to the quest for sustainable development.Photocatalytic hydrogen production from water splitting coupled with degradation of organic pollutants can use solar energy to reduce the toxicity of organic wastewater while cooperatively decomposing water to produce H2,so as to achieve the purpose of coupling pollutant treatment and new energy development,which is a very attractive solution to pollution and energy shortage.In this paper,the latest research progress on the simultaneous photocatalytic degradation of organic pollutants and H2 production by using sunlight is reviewed.The photocatalysts for the catalytic degradation of organic pollutants coupled with photocatalytic water splitting to produce hydrogen were highlighted.The relevant mechanisms were discussed,and the progresses in this emerging research field were briefly summarized and prospected.
