“…Therefore, in 1 M KOH solution and at different scanning rates, the ECSA of the catalyst was calculated from the double-layer capacitance ( C dl ) values of the CV curves in the non-Faraday region. 41 In the voltage range of 1.12–1.17 V, the C dl value (6.4 mF cm −2 ) of NiO–CrO@N–C is greater than that of NiO@N–C (4.2 mF cm −2 ), that is, the ECSA of NiO–CrO@N–C is higher than that of NiO@N–C (Fig. 4c–e), which is consistent with electrochemical results.…”

Electrolysis is a trend in producing hydrogen as a fuel for renewable energy development, and urea electrolysis is considered as one of the advanced electrolysis processes, where efficient materials still need to be explored. Notably, urea electrolysis came into existence to counter‐part the electrode reactions in water electrolysis, which has hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Among those reactions, OER is sluggish and limits water splitting. Hence, urea electrolysis emerged with urea oxidation reaction (UOR) and HER as their reactions to tackle the water electrolysis. Among the explored materials, noble‐metal catalysts are efficient, but their cost and scarcity limit the scaling‐up of the Urea electrolysis. Hence, current challenges must be addressed and novel efficient electrocatalysts are to be implemented to commercialize urea electrolysis technology. Phosphides, as an efficient UOR electrocatalyst, have gained huge attention due to their exceptional lattice structure geometry. The phosphide group benefits the water molecule adsorption, and water dissociation and facilitates the oxyhydrate of the metal site. This review provides a summary of recent trends in phosphide‐based electrocatalysts for urea electrolysis, discusses synthesis strategies, and crystal structure relationship with catalytic activity, and presents the challenges of phosphide electrocatalysts in urea electrolysis.
