The dye solution was stirred with the catalysts in dark for 15 h to ensure complete adsorption–desorption equilibrium prior to the degradation and then the suspension was illuminated with visible light irradiation. The Ti-MCM-41-10 sample shows better degradation efficiency than Ti-MCM-48-10. The degradation of rhodamine B follows pseudo first-order kinetics as illustrated in Fig. 10, and the apparent rate constant (kapp) was found to be 3.17 × 10−3 min−1 for Ti-MCM-48-10, whereas Ti-MCM-41-10 showed a somites rate constant of 4.55 × 10−3 min−1.
