METHOD FOR THE GREEN SYNTHESIS OF GOLD AND GOLD-PALLADIUM NANOPARTICLES AS CATALYSTS IN THE MATRICES OF NATURAL ZEOLITES OF THE CLINOPTILOLITE-TYPE.

摘要

The present invention relates to a method for the green synthesis of catalysts, consisting of gold and palladium-gold nanoparticles in natural zeolite matrices of the clinoptilolite-type, wherein the nanomaterials (particles or clusters) are synthesized and confined in the zeolite matrix pores at room temperature using ascorbic acid as a reducer which causes no harm to the environment. The nanomaterials synthesized in the zeolite networks pores improve this process by performing catalysis on specific contaminants, for example, gold nanoparticles used for methylene blue degradation and gold-palladium nanoparticles used for organochlorine compounds dechlorinating. The invention also describes a method for dyes degradation and organochlorine compounds dechlorinating by a filter housing the synthesized zeolite-nanoparticle composite therein, as well as the design thereof.
