摘　　要：氢能是当今社会受到人们青睐的一种可再生能源,但传统制氢所需的能量高,不容易制备,限制了氢能的应用。Ti O_(2)的比表面积大,带宽充足,具有较高的光催化活性,但Ti O_(2)的能隙宽,对太阳光的利用率低,只有紫外线部分能被利用。为了充分利用太阳能,科研人员对Ti O_(2)进行修饰,以提高Ti O_(2)吸收可见光的效率。本文从光催化机理、Ti O_(2)光催化剂改性、光催化制氢的进展、影响制氢的因素等方面,综述了Ti O_(2)光催化剂改性和制氢的研究进展,对Ti O_(2)改性可以提高光催化活性,提高Ti O_(2)光催化制氢的效率。Hydrogen energy was a kind of renewable energy which was favored by people in today’s society.However,the traditional hydrogen production needed high energy and was not easy to obtain,so it limited the application of hydrogen energy.Ti O_(2) had large speci?c surface area and suf?cient broadband,and had high photocatalytic activity.However,TiO_(2) had a wide energy gap and low utilization rate of sunlight.In order to make full use of solar energy,it was necessary to modify TiO_(2) to improve the absorption of visible light.In this paper,the research progress of TiO_(2) photocatalyst modi?cation and hydrogen production from the aspects of photocatalysis mechanism,TiO_(2) photocatalyst modi?cation,progress of photocatalytic hydrogen production,factors affecting hydrogen production,were reviewed.Through the modi?cation of TiO_(2),the photocatalytic activity and the ef?ciency of TiO_(2) photocatalytic hydrogen production could be improved.
