Water splitting by an electrochemical method to generate hydrogen gas is economic and green approach resolve the looming energy environmental crisis. Designing a composite electrocatalyst having integrated multichannel charge separation, robust stability, low-cost facile scalability could be considered address issue of evolution. Herein, we report superhydrophilic, noble-metal-free bimetallic nanostructure TiO2/Ni2P coated on graphitic polyacrylonitrile carbon fibers (g-C/TiO2/Ni2P) using hydrothermal followed phosphorylation. In aqueous-based route, PAN dissolved in water presence ZnCl2, wet-spinning prepare scalable PAN/ZnCl2 fibers. The nitrogen-contained porous are prepared via pyrolysis fibers; now ZnCl2 acts as volatile porogen form matrix structures. Finally, as-prepared electrochemically activated incorporating active sites. materials formed this work show excellent electrocatalytic activity for evolution reaction. as-synthesized g-C/TiO2/Ni2P catalyst shows low overpotential, its improved, efficiency better than that commercial Pt/C catalyst. At current density −10 mA/cm2, overpotential 55 mV, while 77 mV. Our provides aqueous route with no need noble metals can potential alternative
