Abstract

Abstract: Metastable metallic phases of transition‐metal dichalcogenide (TMD) nanomaterials have displayed excellent performance and emerged as promising candidates for sustainable energy sources low‐cost storage and conversion because of their two‐dimensional (2D) layered structures and extraordinary physicochemical properties. In order to broaden the range of potential applications, defect engineering is applied to the metastable phases of TMDs for further improvement of their catalytic and electronic properties. According to some recent studies, effective introduction of defects without perturbing the interior conductivity contributes to the development of metastable TMDs. This review provides deep insights into recent progress in electrochemistry using defect engineering in the metastable phases of TMDs. After introducing the structures of metastable phases and methods for defect construction, significant developments in catalysis and energy storage applications are discussed to elucidate structure‐function relationships. Key challenges and future directions for defect engineering in the metastable phases of TMDs are also highlighted in the conclusions. Abstract : The metastable phases of TMD nanomaterials have been wildly used for electrochemical field because of their high specific surface area and excellent electrochemical activity. For further contribution to the development of metastable TMD‐based materials, defect engineering is applied to metastable phases to improve their catalytic and electronic properties. This review summarizes recent progress of defect engineering in metastable TMD nanomaterials for electrochemical use.
