Abstract Low‐platinum‐group metal (low‐PGM) catalysts play a crucial role in reducing the cost of proton exchange membrane fuel cells (PEMFCs). Dual‐atomic offer valuable solutions due to their exceptional performance. This work explores application axial Cl‐coordinated Pt─Co dual atoms on N‐doped graphitic carbon (Pt 1 Co /NC─Cl) utilizing PtCo dual‐atomic catalysts, demonstrating ability significantly enhance acidic oxygen reduction reaction (ORR) catalytic performance conventional catalysts. The half‐wave potential (E 1/2 ) reaches 0.841 V 0.1 M HClO 4 solution, and only 12 mV E is observed after 5000 cycles. Axial Cl proves be resistant removal during electroreduction reaction. Consequently, use heteroatom‐modulated asymmetric structures can greatly improve Pt‐based Incorporating nonmetallic synergistic Pt‐group metals presents promising solution for achieving high‐performance Low‐PGMs.

Abstract Transition metal‐based chiral nanomaterials have emerged as a highly promising class of electrocatalysts, uniquely combining the intrinsic electrocatalytic activity transition metals with properties that arise specifically from chirality. In particular, chirality‐induced spin selectivity (CISS) effect, which modulates electron polarization, has provided powerful approach to controlling reaction pathways and enhancing catalytic performance. Substantial advances are achieved in both synthesis application these nanomaterials, leading improvements variety reactions. Nevertheless, deeper understanding formation mechanisms diverse structures mechanistic relationship between configurations improved performance is still needed. This review systematically examines synthetic strategies for constructing different structural features. An in‐depth discussion CISS effect its role wide range reactions then provided. Finally, current challenges assessed, offer perspectives on future research directions such leveraging machine learning‐assisted design advanced situ spectroscopy accelerate development chiral‐enabled, spin‐selective systems.
