Abstract
The invention refers to processes for obtaining catalysts for purification of gases containing toxic materials. Summary of the invention consists in, that it is proposed a process for obtaining a metallic catalyst, which includes deposition of intermetallic compounds upon a carrier at further leaching of one of the compounds. As a carrier it is used a metallic gauze. The nickel-cobalt-palladium intermetallic compounds with phosphor and bor additives are applied on the gauze by the electrochemical metals deposition at 20-30 degree C, pH of 8,5...9,5 and cathode current density of 2...4 A/dm2 from the electrolyte containing in g/L: nickleous chloride 30...50, cobaltichloride 10...15, palladium chloride 3...5, ammonium chloride 120...150, sodium hypophosphite 10...15, dimethylaminoborane 1,0...1,5. Thereafter it is carried out alitizing of metals layer into the aluminium alloy (alloy D 16) and leaching of one of the intermetallic compounds component with a solution of sodium hydroxide in g/L 500...700 and sodium nitrate 60...70 at 100...140 degree C.The result consists in increasing the specific catalyst active surface and adhesion thereof to the metallic carrier at temperature abrupt changes during use thereof.Claims: 2
