Low-platinum-group metal (low-PGM) catalysts play a crucial role in reducing the cost of proton exchange membrane fuel cells (PEMFCs). Dual-atomic catalysts offer valuable solutions due to their exceptional performance. This work explores the application of axial Cl-coordinated Pt─Co dual atoms on N-doped graphitic carbon (Pt1Co1/NC─Cl) catalysts utilizing PtCo dual-atomic catalysts, demonstrating their ability to significantly enhance the acidic oxygen reduction reaction (ORR) catalytic performance of conventional PtCo catalysts. The half-wave potential (E1/2) reaches 0.841 V in a 0.1 M HClO4 solution, and only a reduction of 12 mV in E1/2 is observed after 5000 cycles. Axial Cl proves to be resistant to removal during the electroreduction reaction. Consequently, the use of heteroatom-modulated asymmetric structures can greatly improve the performance of Pt-based catalysts. Incorporating nonmetallic synergistic Pt-group metals presents a promising solution for achieving high-performance Low-PGMs.

The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
