Liquid-Phase Deposition Synthesis of ZIF-67-Derived Synthesis of Co3O4@TiO2 Composite for Efficient Electrochemical Water Splitting

In this article, a novel Co3O4@TiO2 composite is synthesized by applying two-step methods. ZIF-67 and used as template for the synthesis of composite. The designed using effective photocatalytic properties Co3O4 TiO2. resulting supposed to offer superior compared their counterparts. characterized powder X-ray diffraction (PXRD), Brunauer–Emmet–Teller (BET), atomic force microscopy (AFM), scanning electron (SEM), transmission (TEM). Electrochemical water splitting, including hydrogen evolution reaction (HER) oxygen (OER) studies on composite, evaluated cyclic voltammetry (CV) linear sweep (LSV) analysis in 2M aqueous KOH electrolyte. current generation stability these samples deliberated chronoamperometric measurements. It observed, from LSV results at 1 mV/s scan rate, that metal oxides incorporated other have higher density lower onset potential pure oxides. From obtained results, it has become evident possess significant electrochemical splitting with lowest potential, highest density, better OER, HER activity.
