DOIAbstract
The desire to protect the environment for futuregenerations has led to the reutilization of all recoverableand recyclable wastes. Consequently, different residuesfrom various sources were collected to make mixed compoundsto be used as catalyst supports. Such wastesincluded sand and cement from the building industry,nonreturnable glass bottles, and used tires. The synthesizedsupports were impregnated with molybdophosphoric acid,a heteropolyacid with Keggin structure, and characterizedby potentiometric titration, optical microscopy, SEM?EDS,and textural property analyses. The bifunctional propertiesof the new catalysts were evaluated in two relevant transformationsin green conditions: (i) the selective oxidationof sulfides to sulfoxides using...
