| Abstract:In this study, a cerium metal-organic framework material (Ce-MOF) was synthesized via a hydrothermal method, and palladium (Pd) nanoparticles were loaded onto it using an impregnation-reduction method, resulting in the preparation of Pd/Ce-MOF catalysts. The Microscopic morphology and structural changes of the catalysts were systematically investigated. To explore the catalytic reduction and degradation performance of Pd/Ce-MOF catalysts toward azo dyes, sodium borohydride was employed as the reducing agent, and the catalytic performance of Pd/Ce-MOF catalysts with varying Pd loadings was studied for the degradation of methyl orange dye. The results demonstrated that the Pd/Ce-MOF catalyst with a mass fraction of 0.8% achieved complete reduction and degradation of methyl orange within 1 minute, outperforming other catalysts and exhibiting the best performance. Moreover, it maintained a conversion rate of 90.7% after five cycles. These findings indicated that the porous structure of Ce-MOF significantly enhanced the dispersion of Pd nanoparticles and increased the number of active sites, thereby improving the catalytic performance. |
