Abstract Recently, metal‐based atomically thin materials (M‐ATMs) have experienced rapid development due to their large specific surface areas, abundant electrochemically accessible sites, attractive chemistry, and strong in‐plane chemical bonds. These characteristics make them highly desirable for energy‐related conversion reactions. However, the insufficient active sites slow reaction kinetics leading unsatisfactory electrocatalytic performance limited commercial application. To address these issues, defect engineering of M‐ATMs has emerged increase modify electronic structure, enhance catalytic reactivity stability. This review provides a comprehensive summary strategies M‐ATM nanostructures, including vacancy creation, heteroatom doping, amorphous phase/grain boundary generation, heterointerface construction. Introducing recent advancements in application electrochemical small molecule reactions (e.g., hydrogen, oxygen, carbon dioxide, nitrogen, sulfur), which can contribute circular economy by recycling molecules like H 2 , O CO N S. Furthermore, crucial link between reconstruction atomic‐level structure activity via analyzing dynamic evolution during process is established. The also outlines challenges prospects associated with M‐ATM‐based catalysts inspire further research efforts developing high‐performance M‐ATMs.

Anode catalysts are important for direct methanol fuel cells (DMFCs) of energy conversion. Herein, we report a novel strategy by ethylene glycol-based deep eutectic solvents (EG-DESs) the fabrication multi-walled carbon nanotubes (MWCNTs)-supported Pt nanoparticles catalyst (referred to as Pt/CNTs-EG-DES). The Pt/CNTs-EG-DES provides an increased electrochemically active surface area (ECSA) and shows remarkably improved electrocatalytic performance towards oxidation reaction compared Pt/CNTs-W (fabricated in water) commercial Pt/C catalysts. is attributed generation more Pt-O bonds which change electronic states atoms special node structure that obtains sites high CO resistance. This study suggests effective synthesis Pt-based electrocatalysts with DMFC applications.
