Application of titanium doped g-C3N4 for the degradation of toxic dyes in textiles wastewater

G-C3N4 (GCN) is becoming a potential material for organic synthesis, electrodes, photocatalyst, and hydrogen storage. Moreover, it only consists of carbon and nitrogen elements that makes environmentally safer and cheaper than metal-based material. In this research, the sythesis of photocatalyst titanium doped on g-C3N4 was performed under variation of titanium contents with melamine and TiO2 as raw meterial. crystal characterization techniques X-ray diffraction (XRD) was used for undertanding the characteristics of material. The performance of catalyst was tested to degrade the Rhodamine B dyes solution. Based on UV-vis spectrophotometric analysis, doping Ti increases the ability of photocatalyst photodegradation because it can expand the area of light absorption and dyes in photocatalysts. Degradation using lone g-C3N4 can decolor dyes as much as 31.67% of the initial dye concentration, while Ti doped-g-C3N4 can decolor dyes up to 77.65% of the initial dye concentration.
