Embodiment 1
[0022] 100gZrOCl 2 8H2O and ammonia water (containing 10gHN 3 ) was prepared into a mixed solution, which was slowly stirred at room temperature for 4 hours to form a viscous glue; the resulting glue was dried at 300°C for 3 hours to obtain an amorphous ZrO 2 ; the amorphous ZrO 2 Put it into a low-temperature plasma reactor, fix it in the discharge area; pass hydrogen gas into the reactor at a certain flow rate at room temperature, and treat it for four hours at a discharge power of 20W to obtain ZrO 2-x ; Take ZrO 2-x Mix well with an appropriate amount of chloroplatinic acid solution, immerse at room temperature for 12 hours, and then dry and dehydrate at 100°C to obtain a catalyst precursor with a noble metal loading of 0.2%. The gas flow rate of min was passed into helium, and the volatile organic compound catalytic combustion catalyst was obtained by plasma discharge and treated under the condition of discharge power of 5W for 2 hours. The obtained catalyst is put in...
