Embodiment 1
[0021] 125ml of isopropanol and 12.5ml of isopropyl titanate were mixed evenly, and under the condition of magnetic stirring and reflux, they were added dropwise in a 500ml round-bottomed flask equipped with water and isopropanol within 30min (the amount of water and isopropanol The ratio is 50:1), after the hydrolysis is complete, continue to stir and reflux for 2h. The reaction solution was transferred into a 50ml polytetrafluoroethylene-lined hydrothermal kettle, reacted at 80°C for 1 day, centrifuged and precipitated, and washed with distilled water to obtain pure anatase nanospheres. Move to a muffle furnace and bake at 1000°C for 10 hours to obtain pure rutile nanospheres. Take 1g of pure rutile TiO 2 The nanospheres were dispersed into 200ml of methanol-water reaction solution with a methanol volume fraction of 30%, and 0.3ml of chloroplatinic acid (1g / 10ml) was added according to the loading capacity of 3%, magnetically stirred and nitrogen gas was introduced. After ...
Embodiment 2
[0023] 125ml of isopropanol and 12.5ml of isopropyl titanate were mixed evenly, and under the condition of magnetic stirring and reflux, they were added dropwise in a 500ml round-bottomed flask equipped with water and isopropanol within 30min (the amount of water and isopropanol The ratio is 50:1), after the hydrolysis is complete, continue to stir and reflux for 2h. The reaction solution was transferred to a 50ml polytetrafluoroethylene-lined hydrothermal kettle, reacted at 80°C for 1 day, centrifuged and precipitated, and washed with distilled water to obtain pure anatase nanorods. Moved to the muffle furnace, roasted at 550°C for 5 hours to obtain TiO with anatase and rutile ratio of 30:70 2 Nano stave. Take 1g of TiO with a ratio of anatase and rutile of 30:70 2 The nanorods were dispersed into 400ml of methanol-water reaction liquid with a methanol volume fraction of 50%, and 0.2ml of palladium chloride (1g / 10ml) was added according to the loading capacity of 2%, and ni...
Embodiment 3
[0025]125ml of isopropanol and 12.5ml of isopropyl titanate were mixed evenly, and under the condition of magnetic stirring and reflux, they were added dropwise in a 500ml round-bottomed flask equipped with water and isopropanol within 30min (the amount of water and isopropanol The ratio is 50:1), after the hydrolysis is complete, continue to stir and reflux for 2h. The reaction solution was transferred to a 50ml polytetrafluoroethylene-lined hydrothermal kettle, reacted at 80°C for 1 day, centrifuged and precipitated, and washed with distilled water to obtain pure anatase nanorods. Move to a muffle furnace and bake at 600° C. for 8 hours to obtain nanorods with a ratio of anatase and rutile of 20:80. Get 1g anatase and rutile ratio and be that 20:80 nanorod is dispersed in the methanol-water reaction solution of 300mL methanol volume fraction 30%, add 0.4ml chloroauric acid (1g / 10ml) by loading capacity 4%, magnetically stir and Vacuum. After removing the oxygen in the syst...
