Abstract

The invention discloses a preparation method of a metal alloy catalyst, and relates to the technical field of catalyst preparation. The preparation method of the metal alloy catalyst comprises the following raw materials: 20-30% of a ruthenium trichloride solution, 20-30% of an iridium trichloride solution, 22-28% of a potassium tetrachloroplatinate solution, 12-18% of a chelating agent, 10-15% of tin dioxide and 5-15% of a weakly alkaline acidic salt solution. The preparation method comprises the eight steps of raw material mixing, chelating agent adding, constant-temperature gelling, high-temperature evaporation, grinding into powder, PH adjusting, drying and grinding and high-temperature calcination. According to the preparation method of the metal alloy catalyst, various metals can be conveniently regulated and controlled, so that the metal alloy catalysts with different atomic ratios can be obtained by effectively adding raw materials with different parameter proportions, and the problems that the traditional metal alloy catalyst preparation process is complicated, the input raw materials are difficult to regulate and control can be effectively solved, and the preparation cost of the metal alloy catalyst can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of catalyst preparation, in particular to a method for preparing a metal alloy catalyst. Background technique [0002] Alloy catalysts are also known as bimetallic catalysts, such as the patent with the publication number CN1968746B, in which the catalyst activity of the metal catalyst is improved mainly by controlling the load of the metal particles and the distance between the metal particles, but this method is in the preparation process. The steps in the process are complicated, and the raw material metal input cannot be regulated, so that metal alloy catalysts with different atomic ratios cannot be prepared for comparison, and their performance cannot be compared, and thus cannot be accepted by the majority of users, and it is not easy to promote and use. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provid...
