An effective strategy to boost lattice-oxygen-mediated acidic oxygen evolution

Designing electrocatalysts with high activity and stability for acidic oxygen evolution is pivotal to the development of proton-exchange membrane water electrolyzers. In this issue of Chem, Luo and co-workers found that anchoring RuO2 into robust metal-organic frameworks is an effective way to boost lattice-oxygen-mediated acidic oxygen evolution.

Atomically dispersed Ru oxide catalyst with lattice oxygen participation for efficient acidic water oxidationYao et al.ChemApril 5, 2023In BriefAn atomically dispersed Ru oxide catalyst strategy is reported to anchor Ru oxide on UiO-67-bpydc through Ru–N bonds for the OER under acidic electrolytes. The strong Ru–N bonds between Ru oxide and UiO-67-bpydc could not only accelerate the participation of lattice oxygen but also stabilize the soluble ∗Vo-RuO42− intermediates, leading to outstanding performance and long-term stability of the obtained Ru-UiO-67-bpydc catalyst toward the acidic OER.
