Abstract Platinum is the most efficient catalyst for hydrogen evolution reaction in acidic conditions, but its widespread use has been impeded by scarcity and high cost. Herein, Pt atomic clusters (Pt ACs) containing Pt-O-Pt units were prepared using Co/N co-doped carbon (CoNC) as support. ACs are anchored to single Co atoms on CoNC forming strong interactions. Pt-ACs/CoNC exhibits only 24 mV overpotential at 10 mA cm −2 a mass activity of 28.6 A mg −1 50 mV, which more than 6 times higher...

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...

The photovoltaic-alkaline water (PV-AW) electrolysis system offers an appealing approach for large-scale green hydrogen generation. However, current PV-AW systems suffer from low solar-to-hydrogen (STH) conversion efficiencies (e.g., <20%) at practical densities >100 mA cm −2 ), rendering the produced H 2 not economical. Here, we designed and developed a highly efficient that mainly consists of customized, state-of-the-art AW electrolyzer concentrator photovoltaic (CPV) receiver....
