Synthesis and characterization of cadmium sulfide and titania photocatalysts supported on mesoporous silica for optimized dye degradation under visible light.

ABSTRACT: This research presents a new and improved photocatalyst based on the synergistic effect of three components, CdS, TiO₂, and MCM-41, applying statistical techniques to fine-tune degradation parameters for efficient Methylene Blue (MB) degradation. By creating a library of CdS/TiO₂ nanoparticles systematically loaded onto the mesoporous structure of MCM-41, with different loading percentages (5, 10, 15, 20, and 25% w/w), nanocomposites with high surface area and maximized optical properties were designed and analyzed using material characterization techniques including XRD, FTIR, XPS, UV-Vis DRS, TEM, FESEM, EDS, PL, and BET. Ideal performance was achieved from CdS/TiO₂/MCM-41 (CTM) with a 15% w/w loading, which shows high photocatalytic performance at a neut
