Embodiment 1
[0031] Preparation of composite particles
[0032] S1: Add 0.75Kg nano-ferric oxide and 0.5Kg cyanamide to 45L absolute ethanol, stir magnetically for 2 hours, then dry in an oven at 80°C for 20 hours, put it into a tube furnace after drying, and preheat to 60 The titanium tetrachloride at ℃ is fed into the tube furnace with nitrogen as the carrier, and the titanium tetrachloride is preheated in the bubbler, and the volume flow rate of the nitrogen is controlled to be 200L / min, and the tetrachloride in the bubbler is first passed through. titanium dioxide, and then pass it into the tube furnace, and at the same time pass the ammonia gas deposition reaction at a flow rate of 100L / min for 45min, stop feeding ammonia gas and nitrogen gas carrying titanium tetrachloride after the reaction is completed, and pass inert gas, this The embodiment selects nitrogen gas for illustration, and in a nitrogen atmosphere, calcines at a temperature of 900 ° C for 8 hours to obtain nanometer fer...
Embodiment 2
[0041] Preparation of composite particles
[0042] S1: Add 1Kg nano-ferric oxide and 0.84Kg cyanamide to 50L absolute ethanol, stir magnetically for 2 hours, then dry in an oven at 75°C for 22h, put it into a tube furnace after drying, and preheat it to 60°C The titanium tetrachloride is passed into the tube furnace with nitrogen as the carrier, wherein the titanium tetrachloride is preheated in the bubbler, the volume flow rate of the nitrogen is controlled to be 250L / min, and the titanium tetrachloride first passes through the bubbler. Titanium, then passed into the tube furnace, and at the same time, the flow rate of 120L / min was passed into the ammonia gas deposition reaction for 60min. After the reaction was completed, the ammonia gas and the nitrogen gas carrying titanium tetrachloride were passed into the inert gas. As an example, nitrogen gas is selected for illustration. Under nitrogen atmosphere, calcining at 900°C for 6 hours to obtain nanometer ferric oxide particl...
