摘　　要：半导体光催化是一种利用太阳能来驱动催化反应的技术,因其节能环保而广受关注.部分地表天然矿物具有合适的带隙结构和良好的光吸收能力,能够在环境中发生光催化反应,对环境造成影响.综述了天然矿物光催化反应对环境的影响,包括气相光催化(CO_(2)还原、固氮和硝酸盐转化)和液相光催化(有毒有机污染物降解和灭菌)中的研究进展,总结了天然矿物光催化材料的构建与改性(负载、表面改性和材料复合).探讨了天然矿物光催化材料目前的问题,并展望了其未来发展方向.Semiconductor photocatalysis is a technology that uses solar energy to drive a catalytic reaction.Due to its energy saving and environmentally friendly properties,it has attracted wide attention.Some natural minerals on the earth′s surface have suitable band gaps and efficient light absorption properties,which can induce photocatalytic reaction and affect the environment.Here the environmental effect of natural mineral photocatalysis,including gas-phase photocatalysis(CO_(2)reduction,nitrogen fixation,and nitrate conversion)and liquid-phase photocatalysis(organic pollutants degradation and bacterial inactivation)was reviewed,and the construction and modification of natural mineral photocatalysts(supporting,surface modification and combination)were summarized.The problems of natural mineral photocatalysts were discussed and the future development was prospected.
