## 4 Conclusions  
In summary, a TiO\({}_{2}\)/zeolite photocatalytic material was synthesized through the sol-gel method to facilitate the degradation of organic dyes. The zeolite, which was sourced from ignimbrite residues from the Anashuayco quarry in Arequipa, was obtained in its analcime type, while the TiO\({}_{2}\) was obtained in its anatase form, which is preferred for its photocatalytic activity. Furthermore, the synthesized pure TiO\({}_{2}\) showed a band gap and physisorption parameters like those of commercial TiO\({}_{2}\). Meanwhile, the TiO\({}_{2}\)/zeolite photocatalytic material exhibited superior physisorption properties and dye degradation, achieving a photocatalytic efficiency of 94.71% and 83.93% for solutions of 10 and 20 ppm, respectively, in 60 min. This occurred due to its high specific surface area (169.0788 m\({}^{2}\)/g), larger pore volume (0.04 cm\({}^{3}\)/g), and band gap of 3.14 eV. On the other hand, the TiO\({}_{2}\)/zeolite photocatalytic material can be reused in photocatalytic applications with slight changes in its performance. However, at higher concentrations, this reusability decreases. Zeolite improved the photodegradation performance of the TiO\({}_{2}\)/zeolite material due to its influence on the surface morphology and interaction, favoring the uniform dispersion of TiO\({}_{2}\) nanoparticles and providing more active sites for the adsorption of contaminants. Thus, this TiO\({}_{2}\)/zeolite photocatalytic material based on zeolite obtained from ignimbrite residue effectively removes organic dyes such as methyl orange from water, demonstrating high efficiency and potential applications in wastewater treatment.
