化学有序MAX相与MXenes:从结构设计到功能应用
Chemically ordered MAX phases and MXenes:From structural design to functional applications
摘要
Abstract
This review systematically summarizes recent advancements in chemically ordered MAX phases(o-MAX,i-MAX,s-MAX)and their two-dimensional derivatives,ordered MXenes.We detail the crystal structures,thermodynamic criteria(electronegativity difference,atomic radius difference,size effects),and the evolution from theoretical prediction to experimental synthesis for these three ordered phases.For 2D conversion,selective etching strategies for ordered MAX phases are discussed,highlighting the unique structural features of o-MXene,i-MXene,and s-MXene,particularly the formation of periodic ordered vacancies.Functional applications focus on the critical roles of ordered structures in electrochemical energy storage(capacitance enhancement)and electrocatalysis(vacancy-anchored single-atom strategies).Finally,challenges in synthetic chemistry expansion,precise characterization of ordering,and multifunctional coupling applications are prospected,emphasizing"order engineering"as a pivotal design strategy for next-generation functional materials.关键词
