Embodiment 1
[0025] 1) Commercially available aluminum phosphate powder was calcined at 1300°C and wet ball milled to prepare C-AlPO with an average particle size of 5 μm 4 , and then 0.5g of nano-mullite powder prepared by sol-gel-microwave hydrothermal method (200910218827.9), 1g of C-AlPO 4 The powder and 1g of molybdenum disilicide powder were added to the Erlenmeyer flask, wherein the molybdenum disilicide powder was commercially available molybdenum disilicide, and the average particle size was 10 μm by wet ball milling, and then 200ml of butanol with a purity of ≥99.8% was poured into Prepare the suspension A in the Erlenmeyer flask, then put the suspension A into a 1000W ultrasonic generator to vibrate for 30min, place it on a magnetic stirrer and stir for 15h;
[0026] 2) Add selenium with a purity ≥ 99.7% to the suspension A, so that the concentration of selenium is 1g / L, then put it into a 1000W ultrasonic generator and shake for 30min, take it out and stir it on a magnetic stir...
