摘　　要：二维材料粉体具有比表面积大、催化活性位点丰富、易于溶液加工、微结构可调等特性,在能源、电子器件、催化和环境等领域展现出巨大的应用前景。高品质二维材料粉体的低成本、批量化、微结构调控制备是发展其大规模应用的重要前提。本文总结了基于硅藻土模板法制备二维材料粉体(如石墨烯、石墨双炔、过渡金属氮化物、过渡金属硫属化合物粉体)的研究进展;介绍了所获得的二维材料粉体在能量存储器件、印刷电子学、电催化析氢、废水处理等领域的应用研究;最后讨论了基于硅藻土模板法的二维材料粉体制备研究中尚存的问题与挑战,以及二维材料粉体可能的应用方向。Two-dimensional(2D)material powders are featured with large specific surface areas,ample catalytically active sites,high solution processibilities,and widely tunable microstructures,showing some tremendous application prospects in various fields,such as energies,electronics,catalysis,and environments,etc.Low-cost and batch production of high-quality 2D material powders with tunable microstructures is the vital prerequisite for developing their large-scale applications.This review summarized the research progresses on diatomite-templated syntheses of 2D material powders(e.g,graphene,graphidiyne,transition metal nitrides,and transition metal dichalcogenides powders),and introduced the advances in the applications of as-prepared 2D material powders in energy-storage devices,printed electronics,electrocatalytic hydrogen evolution reactions,and wastewater treatments,etc.In addition,some problems and challenges in diatomite-templated syntheses of 2D material powders were represented,and their potential application directions were also discussed.
