[0017] Weigh 10g of aluminum isopropoxide and dissolve it in 100mL of absolute ethanol, put it into an ultrasonic disperser and disperse it ultrasonically at 200W for 30min to obtain a precursor solution, then add 200mL of 0.1mol / L nitric acid solution and 1L deionized solution to the precursor solution Water, moved into a 60°C water bath, stirred and hydrolyzed for 1 hour to obtain aluminum sol, and set aside; put the castor beans in the stove after drying, and roast them at 90°C for 30 minutes. After the roasting, put the castor beans into the pan The castor bean powder is obtained by manual rolling in a milling tank for 20 minutes and passed through a 60-mesh standard sieve; put the above-mentioned castor bean powder into a wooden retort, cover the castor bean powder with lotus leaves, and put it in a pot Add water to the bottom of the wooden retort, heat up to boiling, and cook for 5 minutes until the steam around the wooden retort is uniform but the castor beans are not ye...
