📄 Abstract（原文）
The development of sustainable hydrogen production pathways is critical for decarbonizing energy systems and advancing a circular, low-carbon economy. In this talk, I will highlight two emerging water electrolysis routes for hydrogen generation that also provide added environmental and chemical valorization benefits. More, specifically, I will discuss our computational understanding of water electrolysis not only as a green hydrogen production process but also as a tunable platform for the selective generation of hydrogen peroxide (H 2 O 2 ) 1,2 and nitric acid (HNO 3 ) 3 . This dual-product strategy enables the decentralized and clean production of H 2 for energy storage while simultaneously generating valuable chemicals, offering a sustainable alternative to the energy-intensive industrial processes for production of H 2 O 2 and HNO 3 . By examining the multi-electron oxidation pathways, we identify the structure-function relationships that control product selectivity and pinpoint catalytic structures and compositions that enable high Faradaic efficiency for each water-electrolysis reaction.
