NON-HYDROTHERMAL TiO2/MESOPOROUS SILICA BASED CTAB-GELATIN DUAL TEMPLATE AS LOW-COST PHOTOCATALYST FOR METHYLENE BLUE REMOVAL
Abstract
Abstract - Numerous photocatalytic methods were undertaken to eliminate the toxic chemicals such as methylene blue. Non-hydrothermal synthesis approach for photocatalyst material preparation conducted at room temperature to lessen the energy consumption and expenses.The mesoporous silicaand the TiO2/silica composite were successfully synthesized by these non-hydrothermal approachutilizing TEOS as the silica source and gelatin-CTAB as the dual template.After 1 wt% TiO2 impregnation, the surface area, pore size, pore volume, particle size, and crystallinity of the impregnated material changed to 735 m2/g, 4.8 nm, 0.67 cc/g, 1.1 m, and 66%, respectively. In addition, the introduction of Ti element in SMG-NH by non-hydrothermal approach was discovered to feature prominently in enhancing the particle size and photocatalytic degradation of methylene blue from 73% to 82%. Before and after impregnation, the photodegradation kinetics of the samples were more accurately described by the pseudo-second-order model than by pseudo-zero and pseudo-first order models with linearities close to 0.999.
