Unconventional CN vacancies suppress iron-leaching in Prussian blue analogue pre-catalyst for boosted oxygen evolution catalysis

Defect-engineering offers a promising route to vary material properties and reactivities, although the achievable defect types are limited. Here, the authors introduced unusual CN-vacancies in Prussian blue analogue pre-catalysts that can limit Fe leaching and improve oxygen evolution performances.

Bimetallic nickel-molybdenum/tungsten nanoalloys for high-efficiency hydrogen oxidation catalysis in alkaline electrolytes

The lack of efficient and cost-effective catalysts for hydrogen oxidation reaction (HOR) hampers the application of hydroxide exchange membrane fuel cells. Here, authors reported bimetallic MoNi₄ and WNi₄ nanoalloys with marked HOR activity in alkali, among which MoNi4 outperforms the Pt/C catalyst.

Electroreduction of diluted CO₂ to multicarbon products with high carbon utilization at 800 mA cm^–2 in strongly acidic media

The direct electro-reduction of diluted CO₂ in acidic media can circumvent CO₂ purification and reduce carbon loss. Here, the authors use an ionomer coating layer to enrich the diluted CO₂ and block proton transport, thereby achieving high carbon utilization in diluted CO₂ in an acidic electrolyte.

Boosting the durability of RuO₂ via confinement effect for proton exchange membrane water electrolyzer

Ruthenium dioxide exhibits good activity for the oxygen evolution reaction in acidic conditions but fails to maintain stable performance over long periods. Here, the authors report a confinement strategy that suppresses ruthenium dioxide degradation, enhancing its long-term durability.
