Synergism between the gradient dilution work function and the Janus electronic state of Pt-CoPxBr1−x for boosting alkaline seawater electrolysis

The Pt-CoP x Br 1− x can induce the generation of e − -rich Pt tip region and e − -deficient Pt interf region. The e − -rich region is favorable for hydrogen spillover, while the e − -deficient region will work in the electron-donating OER process.
