The state of palladium and copper on the surface of freshly prepared low temperature carbon monoxide oxidadation catalyst PdCl<sub>2</sub>-CuCl<sub>2/γ</sub>-Al<sub>2</sub>O<sub>3</sub>
The EXAFS/XANES, XRD, SEM methods were used for examination of freshly prepared low temperature carbon monoxide oxidation in air catalyst PdCl2-CuCl2/γ-Al2O3 active components states. The Cu2Cl(OH)3 phase with particle size 100-300 nm and tetrachloropalladat particles were identified on γ-Al2O3 surf...

| description | The EXAFS/XANES, XRD, SEM methods were used for examination of freshly prepared low temperature carbon monoxide oxidation in air catalyst PdCl2-CuCl2/γ-Al2O3 active components states. The Cu2Cl(OH)3 phase with particle size 100-300 nm and tetrachloropalladat particles were identified on γ-Al2O3 surface. According to EXAFS data one of the palladium chloride bonds is longer then another ones. There is no direct interaction between palladium and copper, i.e. there is no common active center including palladium and copper on the γ-Al2O3 surface responsible on the low temperature carbon monoxide oxidation in air. |
