Regulating the electronic structure of metal–organic frameworks via ion-exchanged Ir dispersion for robust overall water splitting

Abstract

A facile ion exchange strategy to fabricate CoIrx–BDC with atomically dispersed Ir, which requires only 9 and 80 mV to deliver 10 and 100 mA cm−2 HER, respectively, and only 245 mV to reach 100 mA cm−2 OER.

Enhanced d–π overlap in a graphene supported Ni/PtNi heterojunction for efficient seawater hydrogen evolution

“…Water electrolysis using abundantly available seawater is an ideal method for low-cost and large-scale hydrogen production. 1–3 Various electrocatalysts have been developed for efficient hydrogen production as the key component of electrolyzers for water splitting. 4–7 In the group investigated thus far, Pt-based materials have been found to possess superior H adsorption properties that make them the most efficient catalyst for the cathodic hydrogen evolution reaction (HER).…”
