of Information Technology2. Institute of Catalytic Material Science, Sichuan University摘 要:Barium oxide was developed successfully to modify palladium catalysts... activity results showed that BaO had a positive effect on the conversion of all pollutants. H2-TPR results suggested that the addition of BaO increased the reductive ability of the palladium catalysts......
by dipping it into chromic acid-sulfuric acid containing a trace amount of palladium. The surface roughness, activity, and valence bond were characterized by atomic force microscopy (AFM) and X-ray... amount of O=C?O functional groups by dipping into Pd contained etching solution, thus the amount of colloids palladium adsorption increases. The carboxyl group acts as the ad- sorption site for the Pd......
