Wastewater pollution is mainly produced from the dye textile industry and most widely used photocatalyst to degrade TiO2 due its photostability, low toxicity, production cost. However, only responsive under UV light; thus, our study extend absorption light visible region via doping of bio-based carbon source, viz. ascorbic acid, produce carbon-doped TiO2. The were solvothermally synthesized with varying loadings (10, 30, 50 wt%) calcination temperatures (250, 300, 400 oC). functional groups determined, which carbonyl (C=O) at 1700 cm-1, alkenyl (C=C) 1630-1670 hydroxyl 3380-3390 appeared 450 cm-1. spectra shifted visible-light band gap was reduced compared undoped photoluminescence results showed that surface oxygen vacancies (SOVs) are generated for Ti–C bond formation proved through diffractogram peak shifting, while crystallite sizes decrease increasing amount decreasing temperature. highest methylene blue photodegradation 89.53% achieved by 30 wt%C-TiO2-250 pH 10 2 h irradiation.
