As a sustainable hydrogen/oxygen production method for the near future, water splitting is still dependent on the appropriate catalysts for acceptable efficiency. Here, for the first time, using silica template, a mesoporous cobalt-cobalt phosphide (Meso-Co/Co₂P) electrocatalyst was produced. For investigating its structure, composition, and morphology, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS) analyses were accomplished. Chronoamperometry, cyclic and linear sweep voltammetry studies exhibited excellent electrocatalytic activity. It needed only an overpotential of 57 mV to produce a 10 mA cm⁻² of anodic current density. A water electrolyzer with Meso-Co/Co₂P as both anode and cathode in an alkaline medium generated a current density of 10 mA cm⁻² at the potential of 1.57 V.

作为在不久的将来可持续的氢气/氧气生产方法，为了达到可接受的效率，水分解仍取决于适当的催化剂。在此，首次使用二氧化硅模板制备了介孔钴-钴磷化物（Meso-Co / Co ₂ P）电催化剂。为了研究其结构，组成和形态，完成了X射线衍射（XRD），X射线光电子能谱（XPS），扫描电子显微镜（SEM）和能量色散X射线能谱（EDS）分析。计时安培法，循环伏安法和线性扫描伏安法研究显示出优异的电催化活性。它仅需要57 mV的超电势即可产生10 mA cm ^-2的阳极电流密度。具有Meso-Co / Co _2的水电解槽在碱性介质中作为阳极和阴极的P在1.57 V的电势下产生10 mA cm ^-2的电流密度。
