Method For Producing Catalyst For Treating Exhaust Gas |
摘要 |
An object of the present invention is to provide a method for producing a catalyst for treating exhaust gas, enabling a smaller amount of a noble metal to be supported and reducing the production cost thereof. There is provided a method for producing a catalyst for treating an exhaust gas containing carbon monoxide and volatile organic compounds, wherein the method comprises: preparing, as a pH buffer solution, an aqueous metal salt solution in which at least one metal salt is dissolved; reductively-treating the aqueous metal salt solution while keeping the pH constant to prepare a metal colloid solution; and immersing a carrier in the metal colloid solution to support the metal on the carrier. The supported amount of metal may be 0.7 g/L or less per one of the metals.
