Novel g-C3N4/CoO Nanocomposites with Significantly Enhanced Visible-Light Photocatalytic Activity for H2Evolution.
Novel g-C3N4/CoO nanocomposite application for photocatalytic H2evolution were designed and fabricated for the first time in this work. The structure and morphology of g-C3N4/CoO were investigated by a wide range of characterization methods. The obtained g-C3N4/CoO composites exhibited more-efficient utilization of solar energy than pure g-C3N4did, resulting in higher photocatalytic activity for H2evolution. The optimum photoactivity in H2evolution under visible-light irradiation for g-C3N4/CoO composites with a CoO mass content of 0.5 wt % (651.3 μmol h-1g-1) was up to 3 times as high as that of pure g-C3N4(220.16 μmol h-1g-1). The remarkably increased photocatalytic performance of g-C3N4/CoO composites was mainly attributed to the synergistic effect of the junction or interface formed between g-C3N4and CoO.
