Abstract This study proposes a novel approach for the rapid transformation of bimetallic NiCo‐oxides into trimetallic NiCoPt alloys using pulsed laser technique in an ethanol medium presence Pt salts. The electrochemical results demonstrate exceptional dual‐functional activity optimized NiCoPt‐10 alloy, effectively catalyzing both hydrogen evolution reaction (HER) and hydrazine oxidation (HzOR). Specifically, alloy presents low overpotential 90 mV at 10 mA·cm −2 HER small working potential 0.068 V versus reversible electrode (RHE) HzOR. In situ Raman spectroscopy theoretical calculations delivered insights alloy. Consequently, overall splitting (OHzS) electrolyzer, employing NiCoPt‐10||NiCoPt‐10 configuration, required only 0.295 to deliver . Notably, this catalyst as cathode combined with Zn foil anode Zn–hydrazine (Zn‐Hz) battery, achieved efficient (H 2 ) production energy efficiency 97%. Furthermore, self‐powered H is realized by integrating Zn‐Hz battery OHzS demonstrating its excellent practical applications. Thus, synthetic strategy can aid designing effective electrocatalysts addressing challenges production.

Abstract In energy conversion processes and various industries, gas evolution reactions (GERs) play an important role. To achieve a future without fossil fuels, the development of high‐efficiency electrocatalysts is necessary, as they directly affect catalytic performance overall efficiency reactions. addition to discovery highly active catalysts, rapid removal gaseous products on electrode surface equally for GERs. The adherence bubbles introduces substantial resistance, significantly diminishing system's efficiency. One promising solution reduce adhesion with superaerophobic levels. These structures, such nanotubes, nanosheets, nanowires, prevent from adhering promote their electrode. aim this review first obtain deep understanding mechanisms related creation surfaces, including characteristics, methods creation, bubble detachment behavior. Furthermore, recent advances in application these surfaces gas‐evolving enhance electrocatalytic properties are discussed. By taking innovative approach, valuable insights can be gained into advancing field electrocatalysis driving progress toward sustainable solutions.
