Embodiment 2
[0029] Raw materials: the carrier is a mixture of aluminum oxide and ceria; the active component of noble metal is palladium; the additive component is sodium nitrate;
[0030] Preparation:
[0031] Step S1, grinding 0.1 g of the precious metal active component palladium into a 400-mesh fine powder, putting the fine powdered palladium into water, ultrasonically dispersing for 20 minutes, and then adding the auxiliary component sodium nitrate to the solution, the sodium content of which is 0.09g, palladium is mixed with the auxiliary component, ultrasonically reacted for 2 hours, and colloid is made;
[0032] Step S2, disperse 100g of the selected carrier into the above-mentioned colloid, place it in a 100-degree water bath for 50 hours, after the deposition is complete, filter and wash, put the filter cake in an oven, the initial temperature of the oven is 70 degrees, press 0.2 degrees / Make the oven temperature rise to 90 degrees at a heating rate of 1 minute, and dry at 90 ...
Embodiment 3
[0036] Raw materials: the carrier is a mixture of ceria and nickel oxide; the active component of noble metal is palladium; the auxiliary component is potassium oxide;
[0037] Preparation:
[0038] In step S1, 0.01 g of the noble metal active component palladium is ground into a 400-mesh fine powder, and the fine powdered palladium is put into water, ultrasonically dispersed for 25 minutes, and then, the auxiliary component potassium oxide is added to the solution, and the potassium content is 0.10g, palladium is mixed with the auxiliary component, ultrasonically reacted for 2 hours, and colloid is made;
