Construction of a wide-spectrum-driven V N -g-C 3 N 4 /Cu 2 (OH) 2 CO 3 heterojunction catalyst from VIS to NIR light via the in situ self-sacrificial method: the effect of oxygen on the N 2 photofixation ability

In this work, an N vacancy-doped g-C 3 N 4 /Cu 2 (OH) 2 CO 3 (V N -GCN/CuCOH) heterojunction catalyst with superior wide-spectrum-driven (from VIS to NIR) N 2 photofixation ability was synthesized via the in situ self-sacrificial method.
