| Abstract: | A new method called adsorption column chromatography for the preparation of supported nano-gold catalysts was proposed.Au/Al2O3 was used as the model catalyst,and low-temperature CO oxidation was used as the model reaction.Effects of pH value of gold precursor solution,liquid-to-solid ratio of the gold precursor solution to the support,specific surface area of the support,and competition adsorbates such as water,ethanol,isopropanol,and acetone on the nano-structure of the gold catalyst were investigated.The... |
