MXenes have gained rapidly increasing attention owing to their two-dimensional (2D) layered structures and unique mechanical and physicochemical properties. However, MXenes have some intrinsic limitations (e.g., the restacking tendency of the 2D structure) that hinder their practical applications. Transition metal chalcogenide (TMC) materials such as SnS, NiS, MoS2, FeS2, and NiSe2 have attracted much interest for energy storage and conversion by virture of their earth-abundance, low costs, moderate overpotentials, and unique layered structures. Nonetheless, the intrinsic poor electronic conductivity and huge volume change of TMC materials during the alkali metal-ion intercalation/deintercalation process cause fast capacity fading and poor-rate and poor-cycling performances. Constructing heterostructures based on metallic conductive MXenes and highly electrochemically active TMCs is a promising and effective strategy to solve these problems and enhance the electrochemical performances. This review highlights and discusses the recent research development of MXenes and hierarchical MXene/TMC heterostructures, with a focus on the synthesis strategies, surface/heterointerface engineering, and potential applications for lithium-ion batteries, sodium-ion batteries, lithium–sulfur batteries, supercapacitors, electrocatalysis, and photocatalysis. The critical challenges and perspectives of the future development of MXenes and hierarchical MXene/TMC heterostructures for electrochemical energy storage and conversion are forecasted.

用于电化学能量存储和转换的分层 MXene/过渡金属硫属化物异质结构
MXenes 因其二维 (2D) 层状结构和独特的机械和物理化学性质而迅速受到关注。然而，MXenes 有一些内在限制（例如，二维结构的重新堆叠趋势）阻碍了它们的实际应用。过渡金属硫属化物 (TMC) 材料，例如 SnS、NiS、MoS 2、FeS 2和 NiSe 2凭借其丰富的地球资源、低成本、适度的过电位和独特的层状结构，引起了人们对能量存储和转换的极大兴趣。尽管如此，TMC材料在碱金属离子嵌入/脱嵌过程中固有的较差的电子导电性和巨大的体积变化导致了快速的容量衰减和较差的倍率和较差的循环性能。构建基于金属导电 MXenes 和高电化学活性 TMCs 的异质结构是解决这些问题并提高电化学性能的一种有前景且有效的策略。本综述重点讨论了 MXenes 和分层 MXene/TMC 异质结构的最新研究进展，重点是合成策略、表面/异质界面工程、锂离子电池、钠离子电池、锂硫电池、超级电容器、电催化和光催化的潜在应用。预测了用于电化学能量存储和转换的 MXenes 和分层 MXene/TMC 异质结构未来发展的关键挑战和前景。
