Visible Photocatalytic Oxygen Evolution over Co and Ni doped gC3N4/rGO

Water splitting which contains two processes, the hydrogen and oxygen evolution, because of the importance of the energy in the world has attracted extensive attentions recently. photocatalytic H2 and O2 generation could be photocatalyzed by visible light over g-C3N4 catalysts. At this study, the nanocomposite CoNi/g-C3N4/rGO was synthesized by hydrothermal method. In order to characterize this nanocatalyst, some techniques such as XRD, FT-IR and TGA have been used. The photocatalytic activity of this nanocomposite was investigated in solution that contains 100 ml H2O and 1.75 gr Fe(NO3)3.6H2O as a sacrificial reagent (electron acceptor) and 0.1gr nanocatalyst. The total amount of the produced oxygen gas using this nanocatalyst is 2413.9 μmole/gr catalyst
