Suppression of Passivation on Nickel Hydroxide in Electrocatalytic Urea Oxidization (Adv. Funct. Mater. 14/2024)

Passivation Suppression In article number 2313680, Chao Huang, Haozhi Wang, Paul K. Chu, and co-workers present a La plasma immersion ion implantation strategy to modulate the near-surface properties of nickel hydroxide nanosheets, resulting in an elevated current output in electrocatalytic urea oxidization. The stabilizing effect of the implanted La ions on protons in active NiOOH mitigates the competitive oxygen evolution for sustained UOR.
