摘　　要：Two-dimensional(2D)metal oxides and chalcogenides(MOs&MCs)have been regarded as a new class of promising electro-and photocatalysts for many important chemical reactions such as hydrogen evolution reaction,CO_(2) reduction reaction and N2 reduction reaction in virtue of their outstanding physicochemical properties.However,pristine 2D MOs&MCs generally show the relatively poor catalytic performances due to the low electrical conductivity,few active sites and fast charge recombination.Therefore,considerable efforts have been devoted to engineering 2D MOs&MCs by rational structural design and chemical modification to further improve the catalytic activities.Herein,we comprehensively review the recent advances for engineering technologies of 2D MOs&MCs,which are mainly focused on the intercalation,doping,defects creation,facet design and compositing with functional materials.Meanwhile,the relationship between morphological,physicochemical,electronic,and optical properties of 2D MOs&MCs and their electro-and photocatalytic performances is also systematically discussed.Finally,we further give the prospect and challenge of the field and possible future research directions,aiming to inspire more research for achieving high-performance 2D MOs&MCs catalysts in energy storage and conversion fields.二维金属氧化物和硫族化物具有优异的物理化学性质,在光催化和电催化应用方面具有很大的潜力,可用于析氢反应、二氧化碳还原和氮还原等许多重要的化学反应.然而,由于导电率低、活性位点少和激发电荷的快速复合,未经改性的二维金属氧化物和硫族化合物通常显示出相对较差的催化性能.因此,需要对二维金属氧化物和硫族化合物合理的结构设计和化学修饰,从而改善和提高其催化性能.基于此,本综述从插层、掺杂、构造缺陷和界面设计以及与其他功能材料的复合等方面综述了近年来二维过渡金属氧化物和硫族化合物的研究进展.同时,系统地讨论了二维金属氧化物和硫族化合物的形貌、物理化学、电子和光学性质与电催化及光催化性能之间的关系.最后,我们对该领域的前景和挑战以及未来可能的研究方向进行了展望,旨在激发更多的研究来实现基于二维过渡金属氧化物和硫族化合物催化剂在能量存储和转换领域的应用.
