This review summarizes the application of atomically dispersed catalysts in direct liquid fuel cells, including the research on different fuel types. It also highlights the current challenges and future development directions in this field.
Direct liquid fuel cells (DLFCs) have received increasing attention because of their high energy densities, instant recharging abilities, simple cell structure, and facile storage and transport. The main challenge for the commercialization of DLFCs is the high loading requirement of platinum group metals (PGMs) as cat-alysts. Atomically dispersed catalysts (ADCs) have been brought into recent focus for DLFCs due to their well-defined active sites, high selectivity, maximal atom-utilization, and anti-poisoning property. In this review, we summarized the structure-property relationship for unveiling the underlying mechanisms of ADCs for DLFCs. More specifically, different types of fuels used in DLFCs such as methanol, formic acid, and ethanol were discussed. At last, we highlighted current challenges, research directions, and future outlooks towards the practical application of DLFCs.(c) 2021 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
