Synthesis, characterization and electrochemical evaluation of hydrogen storage capacity of graphitic carbon nitride and its nanocomposites in an alkaline environment

摘要: Herein, synthesis of graphitic carbon nitride (g-C3N4) and its nanocomposites with monometallic nickel (Ni-g-C3N4), bimetallic zirconium-nickel (ZrNi-g-C3N4) is reported. New materials for high storage performance are investigated eagerly in electrochemical energy applications. With this aim, the method used evaluation hydrogen capacity (HSC) samples present research work. Synthesis were carried out using a combination thermal hydrothermal methods. The sorption capability g-C3N4 was done after sample characterization. Characterization techniques followed powder X-ray diffraction (XRD), Nitrogen adsorption desorption isotherms measurements at 77 K, thermo-gravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), Field-emission scanning electron microscopy (FESEM) dispersive spectrometry (EDS). Cyclic voltammetric chronopotentiometry an alkaline medium helped to calculate HSC. discharge measured be 82 mAhg−1 g-C3N4, 182 Ni-g-C3N4 380 ZrNi-g-C3N4 1 mAg−1 current density. Catalytic properties metal nanoparticles augment nanocomposites. These help store which serves as safe carrier fuel cell
