Abstract: | "1,2-Dichloroethane (1,2-DCE) is a toxic volatile organic compound, which is harmful to the environment and human health. Herein, we develop a single-atom Ru catalyst anchored on the mesoporous schistose gamma-Al(2)O(3) (Ru SACs/m-gamma-Al(2)O(3)) to enhance the catalytic activity and selectivity toward 1,2-DCE degradation. The Ru SACs/m-gamma-Al(2)O(3) shows low T(50) and T(90) (the temperature for 50 and 90% conversion) of 215 and 289 degrees C, which are lower than those for Ru NPs/m-gamma-Al(2)O(3) (291 and 374 degrees C) and pristine m-gamma-Al(2)O(3) (323 and 386 degrees C). The degradation products are mainly CO(2) (>94%) and HCl (>90%) by using the Ru SACs/m-gamma-Al(2)O(3) catalyst, and almost no byproducts are detected. Furthermore, Ru SACs/m-gamma-Al(2)O(3) also presents excellent anti-chlorine poisoning effect and water resistance during the stability test. This work may shed light on the development of efficient single-atom catalysts for the degradation of industrial pollutants" |
