Embodiment 1
[0036] 56kg of TiCl with a mass concentration of 0.18% 3 Solution, 40kg of allylthiourea, 4kg of a mixture of concentrated hydrochloric acid and concentrated sulfuric acid with a volume ratio of 2:1 was added to a stirring container, heated to 55°C, stirred and mixed in a constant temperature water bath for 2.5h to obtain a mixed solution; then take 87kg of the mixed solution was transferred to a hydrothermal reaction kettle, 7kg of hydrogen peroxide and 6kg of dibenzylidene sorbitol were added, and the hydrothermal reaction was carried out at 500°C for 4 hours, so that the titanium dioxide was transformed from anatase phase to rutile phase, and was Auxiliary coating, and then vacuum drying at 78 ° C for 23 hours to obtain a gel-like material; then take 95 kg of gel-like material and 5 kg of platinum-ruthenium-carbon catalyst, mix and stir vigorously, and then at a temperature of 400 ° C 1. Composite hot-press molding under the condition of 40MPa, and after airflow cooling, a ...
Embodiment 2
[0039] 71kg mass concentration is 0.15% TiCl 3Solution, 26kg of acylthiourea, 3kg of a mixture of concentrated hydrochloric acid and concentrated sulfuric acid with a volume ratio of 2:1 were added to a stirring container, heated to 50°C, stirred and mixed in a constant temperature water bath for 3 hours to obtain a mixed solution; then 92kg of the mixed solution was taken The solution was transferred to a hydrothermal reaction kettle, 5kg of hydrogen peroxide and 3kg of dibenzylidene sorbitol were added, and the hydrothermal reaction was carried out at 480°C for 6 hours, so that the titanium dioxide was transformed from anatase phase to rutile phase, and was coated with additives. Then, vacuum-dry at 75°C for 25 hours to obtain a gel-like material; then take 92kg of gel-like material and 8kg of iron-nitrogen-carbon catalyst and mix them vigorously, and then mix them at a temperature of 350°C and a pressure of Composite hot pressing molding under the condition of 50MPa, after ...
Embodiment 3
[0042] 45kg of TiCl with a mass concentration of 0.2% 3 Solution, 50kg of thiosemicarbazide, 5kg of a mixture of concentrated hydrochloric acid and concentrated sulfuric acid with a volume ratio of 2:1 were added to a stirring container, heated to 60°C, stirred and mixed in a constant temperature water bath for 2 hours to obtain a mixed solution; then 82kg of mixed solution was taken The solution was transferred to a hydrothermal reaction kettle, 10kg of hydrogen peroxide and 8kg of dibenzylidene sorbitol were added, and the hydrothermal reaction was carried out at 520°C for 3 hours, so that the titanium dioxide was transformed from anatase phase to rutile phase, and was coated with additives. Then, vacuum-dry at 90°C for 20 hours to obtain a gel-like material; then take 97kg of gel-like material and 3kg of platinum-ruthenium-carbon catalyst and mix them vigorously, and then mix them at a temperature of 480°C and a pressure of Composite hot pressing molding under the condition...
