Embodiment 1
[0018] Weigh 1.5949 g (6 mmol) Nb 2 o 5 In a plastic beaker, add 10 ml of HF and place in a water bath at 80°C to dissolve until clear, add ammonia water dropwise to adjust the pH to greater than 9, age at 80°C for 2 hours, and purify with deionized water 3 to 4 times during this period. Suction filtration, washing and drying. Dissolve the dried sample in 7.5650 g (36 mmol) of citric acid solution, add 3 ml of hydrogen peroxide, and add 2.0316 g (96 mmol) of strontium nitrate and 0.7140 g (24 mmol) of zinc nitrate after the solution is clarified and 5.0434 g (24 mmol) of citric acid, stirred and dissolved in sol at 80°C, dried at 100°C, calcined at 900°C for 10 h, and ground to obtain Sr 1.6 Zn 0.4 Nb 2 o 7 powder.
Embodiment 2
[0020] Catalyst 10%CdS / Sr 1.6 Zn 0.4 Nb 2 o7 Synthesis. Weigh 2 g of the prepared Sr 1.6 Zn 0.4 Nb 2 o 7 Disperse the powder in 30 ml of water, stir evenly, add dropwise a solution made of 0.1149 g of cadmium acetate, ultrasonically disperse for 15 minutes, add dropwise a solution made of 0.0328 g of thiourea, ultrasonically disperse for 15 minutes, and put the resulting solution into a 100 ml container In a polytetrafluoroethylene reactor, put it into a muffle furnace at 150°C for hydrothermal reaction for 10 hours. The sample after the hydrothermal reaction is filtered, washed, dried and ground for many times to obtain the target catalyst.
Embodiment 3
[0022] Catalyst 20%CdS / Sr 1.6 Zn 0.4 Nb 2 o 7 Synthesis. Weigh 2 g of the prepared Sr 1.6 Zn 0.4 Nb 2 o 7 Disperse the powder in 30 ml of water, stir evenly, add dropwise a solution made of 0.2297 g of cadmium acetate, ultrasonically disperse for 15 minutes, add dropwise a solution made of 0.0656 g of thiourea, ultrasonically disperse for 15 minutes, and put the resulting solution into a 100 ml container In a polytetrafluoroethylene reactor, put it into a muffle furnace at 150°C for hydrothermal reaction for 10 hours. The sample after the hydrothermal reaction is filtered, washed, dried and ground for many times to obtain the target catalyst.
