Development of Alumina-Supported Pd-Ru Nano-Catalysts for Catalytic Reduction Reactions for Water Pollutants in Aqueous Media

Abstract

This study examines the catalytic efficiency of six materials (EG1-6) synthesized on an Al₂O₃ support material using different PdCl₂ and RuCl₃ precursors. The catalyst EG4 (Ru:Pd 3:2) was determined to be superior because of its synergistic impact. The utilization of XRD, SEM-EDX, and TEM techniques unveiled the existence of Al₂O₃, RuO₂, and Pd constituents, exhibiting an average crystal size of around 16 nm. The even distribution of nanoparticles on the Al₂O₃ support is likely to enhance the accessibility of reactants to active sites, leading to an increase in catalytic efficiency.
