Graphitic carbon nitride (g-C3N4) and titanium dioxide (TiO2 composites were synthesized by hydrothermal method and applied as photocatalysts for the degradation of organic dyes for environmental cleanness. The work aims to enhance UV-Visible light-driven photocatalytic activity by combining the advantageous properties of both g-C3N4, a with a narrow bandgap, and TiO2, a well-known but UV-active photocatalyst. The enhanced performance is attributed to the synergistic effect between g-C3N4 and TiO2, where the heterojunction facilitates charge transfer and suppresses electron-hole recombination. It highlights the potential of g-C3N4/TiO2 composites as enhanced, efficient, low-cost photocatalysts for the treatment of dye contaminated wastewater for against the environments and offers insights into the rational design of visible-light-active photocatalytic materials. The rapid growth of industrial activities in the world in turn resulted highly usage of these industrial product of these organic dye pollutants. Industrialization, technologies, and consumption of non-renewable resources have grown at rapidly and polluting the enviroment. The Organic pollutants are series issues due to their effects on the environment including human, air, plants, water as well to all the nature. These major organic pollutants are Methylene Blue (MB), Rhodamine 6G (Rh 6G), Congo Red, Methyl orange and Violin have contributed significant amount different type of chemicals to the pollution of water bodies, air and the environments in different ways. It needs a modern way to get energy from the sun, wind, biofuel, hydropower or other renewable ways for the sake of the environments. The synthesized g-C3N4/TiO2 composites were characterized using Thermogravimetric analysis (TG), X-ray diffraction (XRD), scanning electron microscopy (SEM), Electron diffraction spectroscopy (EDX), Photoluminescence (PL) and UV-Vis diffuse reflectance spectroscopy (DRS) to investigate their structural, morphological, and optical properties.
