2D Metal Phosphorous Trichalcogenides (MPCh₃) for Sustainable Energy Storage and Conversion: Nanoarchitectonics and Advanced Applications

Abstract 2D metal phosphorous trichalcogenides (MPCh₃) have attracted considerable attention in sustainable energy storage and conversion due to their distinct physical and chemical characteristics, such as adjustable energy bandgap, significant specific surface area, and abundant active sites. However, research on 2D MPCh₃ primarily focuses on electrocatalysis, and understanding its energy conversion and storage mechanisms remains incomplete. This review comprehensively summarizes recent advancements in energy storage and conversion using 2D MPCh₃‐based materials of various structures. It begins with a discussion of the distinctive properties and preparation techniques of 2D MPCh₃, followed by a focus on the rational design and development of these materials for diverse energy‐related applications, including rechargeable batteries, supercapacitors, electrocatalysis, photocatalysis, and desalination. Finally, it outlines the key challenges and prospects for future research on 2D MPCh₃ materials.
