Description
Summary:"Successful synthesis of metal–, semiconductor–, and metal/semiconductor–mordenite nanocomposites, using geothermal solid waste as precursor is reported. Powders of nanostructured composites, consisting of metal and/or semiconductor nanoparticles grown on a mordenite-type zeolitic matrix surface, were synthesized by a one-step solvent-free and organic template-free process. The developed methodology is capable of controlling and tuning the final properties of composites from their synthesis and is also reproducible and repeatable. For comparison and demonstration of the application of the final products, dye photocatalysis degradation tests were done using commercial TiO<sub>2</sub> as reference (degradation reached ∼75% in 215 min, k = 0.004 min<sup>−1</sup>), [M]–S–MOR samples revealed better performance (≥95% in 100 min, k = 0.009 min<sup>−1</sup>)."
