Coupling single-atom sites and nanoclusters/nanoparticles: collective catalysis toward the oxygen reduction reaction

The oxygen reduction reaction (ORR) plays a crucial role in the field of energy such as in proton exchange membrane fuel cells (PEMFCs) and zinc-air batteries (ZABs), but the process is kinetically slow and requires efficient catalysts. The high cost and scarcity of Pt-based catalysts limit their practical applications despite their superior performance. Researchers are therefore committed to reducing the use of Pt or developing highly active alternative non-precious metal-based catalysts to reduce costs. Collective effect catalysts (CECs) combine the advantages of single atoms and atomic clusters/nanoparticles and can significantly improve the activity, selectivity and durability of the catalyst by precisely…
