A polymer solution containing 0.5 wt.% polydiallyl dimethyl ammonium chloride was used to modify graphitic carbon nitride by the sol-carbonization method (PDDA (0.5) @ g-C3N4).Titanium dioxide nanoparticles were synthesized by microwave irradiation followed by hydrothermal treatment to obtain titanium nanowires (TiNWs).The TiO2NWs/ (PDDA (0.5) @g-C3N4) nanocomposite was prepared with different wt....
