电解水制氢是未来清洁能源体系中关键转换技术,但阳极析氧反应(OER)受限于其缓慢的动力学,研究OER动力学过程对电解水制氢工业化进程有着极大的促进作用。尽管多孔炭在OER中展现出潜力,但其微结构与析氧催化性能的构效关系有待于深入探究。以梨木为原料,采用H

Electrolytic hydrogen production represents a pivotal conversion technology within future clean energy systems. However
the anodic oxygen evolution reaction (OER) remains constrained by its sluggish kinetics. Investigating the OER kinetic process significantly advances the industrialization of electrolytic hydrogen production. Although porous carbon exhibits potential in OER
the structure-activity relationship between its microstructure and oxygen evolution catalytic performance warrants further exploration. Using pear wood as raw material
a porous carbon catalyst was prepared via a stepwise activation strategy employing H₃PO₄-KOH. This study investigates the structure-activity relationship between the microstructure of porous carbon and its oxygen evolution performance in water electrolysis. The study demonstrates that the stepwise activation strategy enables the formation of a three-dimensional network pore structure within the porous carbon
characterized by high specific surface area and rich micro-mesoporous connectivity. This exposes more structural defects and catalytic active sites on the carbon matrix
facilitating the in-situ enrichment and doping of P and O heteroatoms to generate abundant surface functional groups. This unique structural feature of porous carbon endows it with outstanding oxygen evolution performance in water electrolysis (overpotential of 340 mV@100 mA cm
