Preparation of TiO<sub>2</sub>/g-C<sub>3</sub>N<sub>4</sub> by CTAB-assisted and photocatalytic degradation of unsymmetrical dimethylhydrazine waste water

The TiO<sub>2</sub>/g-C<sub>3</sub>N<sub>4</sub> composites were prepared by the hydrothermal method with cetyltrimethyl ammonium bromide (CTAB). The influence of CTAB on the structural properties and spectral properties of the composites was studied. The samples...
