Published: June 1, 2022

Herein, Pd supported on UiO-66 as well its NH2- and NO2-functional materials with ultra-low loadings (0.05 ​wt%) were synthesized for toluene oxidation. Pd–U, using the support, exhibited superb catalytic performance, water resistance, resistance to SO2. A series of experiments characterizations revealed that a high dispersion small clusters, Pd0/Pdtotal proportion, better adsorption toluene, best activation capacities gaseous oxygen species enhanced degradation over Pd–U. Additionally, mechanism Pd-based catalysts was discussed. Furthermore, water-resistance SO2 concentration influence tested analyzed. Introducing H2O suppressed species, decreased performance three catalysts. The different impacts investigated elucidated. This study provides guidance rationally designing removing under in-field operating conditions.
