【Abstract】 The progress in preparation technology of amorphous alloy catalyst is described. The principles, general process, and characteristics of three preparation methods such as rapid quenching method, chemical plating method and sol - gel method are analyzed. The mechanism of sol - gel method and activity comparison among different kinds of preparation methods are emphatically discussed. It is pointed out that using functional carriers, adding promoters or modifiers, and reducing the price of reduction process are the most important factors in the study on the preparation of amorphous alloy catalysts.更多还原
