Abstract A considerable amount of platinum (Pt) is required to ensure an adequate rate for the oxygen reduction reaction (ORR) in fuel cells and metal‐air batteries. Thus, implementation atomic Pt catalysts holds promise minimizing content. In this contribution, sites with nitrogen (N) phosphorus (P) co‐coordination on a carbon matrix (PtNPC) are conceptually predicted experimentally developed alter d‐band center Pt, thereby promoting intrinsic ORR activity. PtNPC record‐low content (≈0.026...
Iridium (Ir)-based electrocatalysts are widely explored as benchmarks for acidic oxygen evolution reactions (OERs). However, further enhancing their catalytic activity remains challenging due to the difficulty in identifying active species and unfavorable architectures. In this work, we synthesized ultrathin Ir-IrOx/C nanosheets with ordered interlayer space enhanced OER by a nanoconfined self-assembly strategy, employing block copolymer formed stable end-merged lamellar micelles. The...

Abstract Hydrogen peroxide (H 2 O ) production by the electrochemical 2‐electron oxygen reduction reaction (2e − ORR) is a promising alternative to energy‐intensive anthraquinone process, and single‐atom electrocatalysts show unique capability of high selectivity toward 2e ORR against 4e one. The extremely low surface density sites inflexibility in manipulating their geometric/electronic configurations, however, compromise H yield impede further performance enhancement. Herein, we construct...
Abstract Encapsulating metal‐based catalysts inside carbon sheaths is a frequently‐adopted strategy to enhance their durability under various harsh situations and improve catalytic activity simultaneously. Such encapsulation, however, imposes significant complications for directly modifying materials’ surface atomic/electronic configurations, fundamentally impeding the accurate tuning of capabilities. Herein, universal single‐atom alloy (SAA) reported indirectly yet precisely manipulate...
The rational design of advanced catalysts for sodium-sulfur (Na-S) batteries is important but remains challenging due to the limited understanding sulfur catalytic mechanisms.
