Abstract : Eco-friendly strategies to obtain hydrogen fuel from water. Electrocatalytic HER and OER are sustainable methods of producing hydrogen and oxygen gas. In this work, bifunctional electrolytes for excellent catalytic properties were carried out using HER and OER. As-synthesized nickel manganese assisted with and without glycine via simple and cost-effective hydrothermal method were obtained crystalline spinel structure peaks and confirmed the presence of NiMnO3@600, NiMnO3@700, NiMnO3-Gly@600 and NiMnO3-Gly@700. Morphology as a sphere. Pre-preparation Electrode on NiMnO₃-Gly@700 shows high-performance, exhibits enhancing bifunctional HER and OER catalysts compared with other samples. Outer performing electrode shows reaching current density with an excellent HER over potential of 11.69 mV at 10 mA cm−2 and 251 mV at 100 mA cm−2 for particular glycine-assisted sample NiMnO3-Gly@700. The Tafel slope of higher current density 18 mV dec−1 and highly effective retention value were calculated at 99 % for 10,000 cycles at 24 h. The material showed excellent durability during the HER process. This work highlights significant strategies in dual transition metal electrocatalysts in water spitting. These can be promising bifunctional catalysis for HER/OER.
