“…Moreover, cation vacancies facilitate the transfer of charges between the support and the single metal atoms, while anion vacancies possess an optimized local electron configuration in the active center. [ 59 ] Besides, as for organic materials, the introduction of vacancies or structural defects (ring‐opening) can also achieve benefits similar to those of inorganic materials, [ 60 ] as well as to generate more active sites for sustainable energy conversion reactions.

Single‐atom catalysts (SACs) have been demonstrated to show exceptional reactivity and selectivity in catalytic reactions by effectively utilizing metal species, making them a favorable choice among the different active materials for energy conversion. However, SACs are still in the early stage of energy conversion, and problems like agglomeration and low energy conversion efficiency are hampering their practical applications. Substantial researches focus on support modifications, which are vital for SAC reactivity and stability due to the intimate relationship between metal atoms and support. In this review, a category of supports and a variety of surface engineering strategies employed in SA systems are summarized, including surface site engineering (heteroatom doping, vacancy introducing, surface groups grafting, and coordination tunning) and surface structure engineering (size/morphology control, cocatalyst deposition, facet engineering, and crystallinity control). Also, the merits of support surface engineering in single‐atom systems are systematically introduced. Highlights are the comprehensive summary and discussions on the utilization of surface engineered SACs in diversified energy conversion applications including photocatalysis, electrocatalysis, thermocatalysis, and energy conversion devices. At the end of this review, we have discussed the potential and obstacles of using surface engineered SACs in the field of energy conversion. This review aims to guide the rational design and manipulation of SACs for target‐specific applications by capitalizing on the characteristic benefits of support surface engineering.This article is protected by copyright.
