摘　　要：光电催化技术是解决环境污染和能源短缺问题最具应用前景的方法之一。基于半导体矿物的光电化学性质或非半导体矿物的天然物理特性,将矿物与光电催化功能体复合构建的光电催化矿物材料具有成本低、环境相容性好、性能优异等特点,其在矿物利用的新兴领域受到了广泛关注。本文在限定了光电催化矿物材料研究是否属于矿物应用范畴的基础上,介绍了光电催化矿物材料包含的矿物组分及特征,提出了光电催化矿物材料的分类,并对光电催化矿物材料的制备方法及矿物增强光电催化活性的机制进行了讨论。最后,概述了光电催化矿物材料用于水中污染物治理、光电催化水分解产氢、CO_(2)能源化等领域的研究现状;指出应重点关注矿物本征光电属性、有效建立材料复合结构与效能的联系、明确材料矿物学属性影响光电催化的机制等问题,拓展光电催化矿物材料在新能源、化学品合成和矿物/微生物作用等领域的应用研究。Photoelectrocatalytic technology is one of the most promising methods to solve the problems of environmental pollution and energy shortage.Based on the photoelectrochemical properties of semiconductor minerals or the natural physical characteristics of non-semiconductor minerals,the photoelectrocatalytic mineral materials were constructed by compositing mineral with photoelectrocatalytic functional body,with the characteristics of low cost,good environmental compatibility and excellent property,which have received wide attention in the new field of mineral utilization.On the basis of limiting whether the research of photoelectrocatalytic mineral materials belong to the scope of mineral application,the mineral components and characteristics of the photoelectrocatalytic mineral materials were introduced, their classification, preparation methods, as well as the enhanced mechanism of catalytic activity by minerals were discussed. Finally, the research status of photoelectrocatalytic mineral materials used in the treatment of wastewater, hydrogen evolution by photoelectrocatalysis water splitting, CO_(2) energy utilization were summarized. It is pointed out that attention should be paid to the intrinsic photoelectric properties of minerals, the establishment of the relationship between material composite structures and efficiency, and the clarification of the mechanism by which material mineralogical properties affect photocatalysis. The application research of photocatalysis mineral materials in new energy, chemical synthesis, and mineral/ microbial interactions should be expanded.
