High-quality CoP nanorings (CoP NRs) are easily achieved using a phosphorating treatment of CoOOH nanorings, and reveal high activity towards the hydrogen evolution reaction and the nitrate electrocatalytic reduction reaction due to substantial coordinately unsaturated active sites, a high surface area, and available mass transfer pathways. Consequently, the CoP NRs can achieve a faradaic efficiency of 97.1% towards NO₃ ⁻-to-NH₃ conversion and provide an NH₃ yield of 30.1 mg h⁻¹ mg⁻¹ _cat at a −0.5 V potential.

This review summarizes design, synthesis, and interfacial mechanisms of organic interfaces in electrocatalysis, emphasizing their roles in tuning structures, electronics, and environments to improve performance.

As an alternative to the traditional ammonia (NH₃) synthesis method, the electrochemical reduction reaction of nitrate (NO₃⁻RR) for NH₃ production not only mitigates nitrate pollution but also yields economically valuable NH₃.

Pt₁Rh₁@BmimBF₄/CNBs reveal significantly enhanced ORR electroactivity and fascinating ORR selectivity in the presence of methanol compared to Pt₁Rh₁/CNBs nanohybrids without BmimBF₄ due to particular metal–organic interface engineering.
