Atomic thickness catalysts (ATCs) have shown huge prospects in energy conversion applications due to the prominent advantages in large specific surface area and high density of exposed surface atoms over their bulk counterparts. The established ATCs, including metals (alloys), layered double hydroxides (LDHs), transition metal dichalcogenides (TMDs), transition metal oxides (TMOs), and carbon‐based materials, have exhibited higher efficiency and better catalytic stability than that of commercial noble metal‐based nanocrystals for energy conversion related reactions. In this review, important progress is exemplified from the aspects of synthetic methods (e.g., bottom‐up and top‐down methods) and energy conversion related reactions, for instance, oxygen reduction reaction (ORR), formic acid oxidation reaction (FAOR), methanol oxidation reaction (MOR), ethanol oxidation reaction (EOR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and carbon dioxide (CO₂) reduction reaction (CRR). Furthermore, a valuable insight into the remaining challenges and potential opportunities for ATCs is provided in the fields of energy conversion applications.

原子厚度催化剂：合成与应用

原子厚度催化剂（ATC）在能量转换应用中显示出广阔的前景，这是由于与大体积的同类材料相比，大比表面积和高暴露的表面原子密度具有显着优势。既定的ATC，包括金属（合金），层状双氢氧化物（LDH），过渡金属二硫化碳（TMD），过渡金属氧化物（TMO）和碳基材料，比商业贵金属具有更高的效率和更好的催化稳定性。金属基纳米晶体，用于能量转换相关的反应。在本综述中，从合成方法（例如，自下而上和自上而下的方法）以及与能量转换相关的反应（例如，氧还原反应（ORR），甲酸氧化反应（FAOR），₂）还原反应（CRR）。此外，在能量转换应用领域中，还提供了对ATC的剩余挑战和潜在机会的宝贵见解。
