The strategic design and fabrication of efficient electrocatalysts are pivotal for advancing the field electrochemical water splitting (EWS). To enhance EWS performance, integrating non-noble transition metal catalysts through a cooperative double incorporation strategy is important offers compelling alternative to conventional precious metal-based materials. This study introduces novel, straightforward, single-step process fabricating bimetallic MoCo catalyst integrated within three-dimensional (3D) nanoporous network N, P-doped carbon nitride derived from self-contained precursor. subsequent carbonization at 550 °C yields highly effective phosphide electrocatalyst, denoted as MoCoPCN, tailored explicitly EWS. MoCoPCN electrocatalyst demonstrates exceptional electrocatalytic with low onset potential 1.43 V an overpotential value 202 mV current density 10 mA/cm2 oxygen evolution reaction (OER) 49.5 hydrogen (HER), respectively. Moreover, exhibits high electrochemically active surface area 2720 cm–2, small Tafel slope 47.5 dec–1 HER 45.7 OER, charge transfer resistance 0.09 Ω 0.805 OER. optimal was tested overall performance in 1 M KOH electrolyte, demonstrating excellent efficiency cell voltage 1.49 required achieve mA/cm2. These outstanding characteristics, combined synergistic effects arising interaction between P-g-C3N4 (PCN), underscore material promising splitting.
