Abstract The creation of highly efficient and economical electrocatalysts is essential to the massive electrolysis water produce clean energy. ability use urea reaction oxidation (UOR) in place oxygen/hydrogen evolution process (OER/HER) during splitting a significant step toward production high‐purity hydrogen with less energy usage. Empirical evidence suggests that UOR consists two stages. First, metal sites undergo an electrochemical pre‐oxidation reaction, then molecules on high‐valence are chemically oxidized. Here, scandium‐doped CoTe supported carbon nanotubes called Sc@CoTe/CNT reported CoTe/CNT as composite efficiently promote generation from durable active for OER/UOR/HER alkali solutions. Electrochemical impedance spectroscopy indicates facilitates charge transfer across interface. Furthermore, nanocatalyst has high performance KOH KOH‐containing solutions demonstrated by HER, OER, (215 mV, 1.59, 1.31 V, respectively, at 10 mA cm −2 1 m KOH) shows 195 1.61 1.3 respectively. Consequently, total system achieves 1.29 whereas overall device obtaines 1.49 V 1.54, 1.48 This work presents viable method combining HER maximally effective production.
