The activity and stability of Ni‐based electrocatalysts
Research gap analysis derived from 3 chemistry papers in our local library.
The gap
However, the activity and stability of Ni‐based electrocatalysts for the anodic urea oxidation reaction (UOR) are limited by the lack of active NiOOH and strong intermediates adsorption.

The product selectivity of urea electrosynthesis from co-reduction of nitrogen wastes and CO 2 remains mediocre due to the competing nature of the two parallel reduction reactions. The development of a catalyst design that enables high selectivity to urea is needed.

Abstract Nickel‐based catalysts have been regarded as one of the most promising electrocatalysts for urea oxidation reaction (UOR), however, their activity is largely limited by the inevitable self‐oxidation reaction of Ni species (NSOR) during the UOR.
