Crystalline–amorphous core–shell-like heterostructures have attracted considerable attention in electrocatalysis due to their unique electronic and structural properties; however, tuning the surface composition of amorphous shell remains a major challenge. In this work, we report simple, low-cost, one-pot hydrazine-assisted chemical deposition method for synthesizing series Co-doped Ni@Ni(OH)2 catalysts with crystalline Ni core an Ni(OH)2 shell. Among prepared catalysts, sample containing 10 wt.% cobalt (denoted as b-Co-doped Ni@Ni(OH)2) exhibited highest electrocatalytic activity toward both oxygen evolution reaction (OER) urea oxidation (UOR). 1.0 M KOH, catalyst achieved 40 mV lower overpotential at 50 mA·cm−2 compared undoped OER. For UOR 0.33 urea/1.0 it delivered approximately twice anodic current density relative sample, along improved kinetics evidenced by Tafel slope 70.7 mV·dec−1. This performance enhancement is attributed optimized architecture, doping-induced modulation, increased electrochemically active area, charge transfer efficiency. Overall, study demonstrates promising scalable strategy designing advanced Ni-based bifunctional sustainable energy conversion wastewater treatment applications.
