Description :
The simple Sol-gel method was adopted to synthesize carbon-doped TiO2 nanophotocatalysts that worked better in visible light. For carbon doping, microcrystalline cellulose (MCC) was used. The prepared carbon-doped TiO2 samples were calcined at 400–600 °C. Carbon-doped nanophotocatalysts were analyzed using XRD and SEM. The image obtained from the SEM shows that C-doped TiO2 synthesis in the presence of MCC also restricted TiO2 nanoparticle development and regulated the size and aggregation of nanoparticles. In contrast to pure nanoparticles, carbon doping enhanced the photocatalytic activity of the TiO2 photocatalyst in the degradation of methylene blue dye. Carbon-doped TiO2 attained an efficiency of 98% and 60% under UV and visible lights, respectively.
