摘　　要：辉钼矿作为一种自然界储量丰富的矿物,其纳米片具有巨大的比表面积、独特的光电性能及优异的机械性能,并且已引起科研工作者的广泛关注。课题组深入研究了辉钼矿纳米片微观结构对其重金属离子亲和性、能带结构和光热转换能力的影响。同时针对目前选矿行业所面临的氰化提金环境危害大、矿山废水难以有效处理及高盐水浮选难以有效实施等问题,开展了辉钼矿纳米片对硫代硫酸盐浸出液中金回收、水体中重金属离子脱除和有机物降解、高盐水淡化处理等研究。回顾并梳理了课题组近期关于辉钼矿纳米片的研究工作,整理了辉钼矿纳米片的功能化改性思路,并对辉钼矿纳米片功能材料在这几个方向应用的优越性和潜力进行了评估。最后对辉钼矿纳米片功能材料的发展趋势及未来在湿法冶金和环境治理方面的实际应用前景及挑战进行了展望。Molybdenite,a mineral with abundant natural reserves,has attracted extensive attention from researchers,due to the huge specific surface area,excellent photoelectric and mechanical properties of its nanosheets. Investigate effectof the microstructure of molybdenite nanosheet on its heavy metal ions affinity,band gap and photothermal performance. Aim-ing at solving the problem of the high pollution of cyanidation gold extraction,the ineffective mineral processing wastewatertreatment,the ineffective implementation of high salt water flotation,the functionalized molybdenite nanosheets are appliedto recover gold from thiosulfate solution,remove heavy metal ions and organics from water,desalination of high salt water. Re-views our recent work of molybdenite nanosheet functional materials researches and evaluates the potential of its applicationin those fields. Furthermore,this manuscript looks forward to the development trend of molybdenite functional materials andtheir future practical application prospects and challenges in hydrometallurgy and environmental remediation.
