(a) Effect of initial dye concentration on photocatalytic degradation of MG using TiO₂ (P25) (photocatalyst amount = 0.75 g/L and irradiation time = 180 min at pH = 7). (b) Effect of initial dye concentration on photocatalytic degradation of MG using TiO₂/NC (photocatalyst amount = 0.75 g/L and irradiation time = 180 min at pH = 7).
