摘要Preferential oxidation of the H-2 impurity in CO streams is crucial for the catalytic conversion of CO into ethylene glycol. It is uncertain as to whether H-2 can overthrow the dominance of CO and finally lead the reaction. Not only is this a typical research issue, but it is also extremely critical for practical applications. So far, no catalyst has shown selectivity higher than 50% owing to competitive adsorption of CO. In this work, we report a PdClx-based catalyst that can readily overcome the challenge mentioned above. Over this catalyst, the selectivity of H-2 oxidation is promoted by more than 40% relative to that over the conventional Pd/Al2O3 catalyst and reaches a value of 87%. The turnover frequency of undesired CO oxidation is inhibited by at least one order of magnitude. We found that the reconstructed palladium chloride was highly selective to this reaction by facile inhibition of the adsorption and oxidation of CO.
