A novel biomass carbon (BC) modified Z-scheme g-C₃N₄/Co₃O₄ heterojunction photocatalyst (BC/g-C₃N₄/Co₃O₄) has been constructed via a facile approach. In addition, various kinds of characterization methods, including TEM, XPS, UV–vis DRS, VSM, photoluminescence spectra, photocurrent response, electrochemical impedance spectroscopy, etc. are applied to investigate the morphology structure, optical property, magnetic properties and electronic properties of BC/g-C₃N₄/Co₃O₄. The BC/g-C₃N₄/Co₃O₄ is applied as novel photocatalyst to degrade various pollutants and it exhibits remarkable photocatalytic activity and stability as compared to pure g-C₃N₄ and Co₃O₄. Furthermore, the BC/g-C₃N₄/Co₃O₄ can be effectively separated from solution in favor of practical applications.
