Embodiment example 1
[0015] First, 0.2g P123 was added to 10mL cyclohexane, stirred at 60°C for 2h, then 0.6mmol tetrabutyl titanate was added, and stirred at 60°C for 2h to obtain a clear mixed solution (referred to as solution A). Then the above-mentioned mixed solution is slowly added to the reactor containing 5mL of acid solution (referred to as solution B), and the two kinds of solutions appear to be stratified in the reactor. Small solution B. The reaction kettle was sealed, and slowly placed in an oven at 160° C. for 20 h. After the reactor was cooled to room temperature, the product was obtained between the two-phase interface of solution A and solution B. After filtering, washing with water and drying, a two-dimensional carbon film-coated sea urchin-like titanium dioxide composite material is obtained. Scanning electron micrographs and XRD patterns of the product are shown in Figure 1-2 shown.
Embodiment example 3
[0017] Firstly, 0.2 g of P123 was added to 10 mL of cyclohexane, and after stirring at 60° C. for 2 h, 0.6 mmol of titanium isopropoxide was added, and stirring was continued at 60° C. for 2 h to obtain a clear mixed solution (referred to as solution A). Then the above-mentioned mixed solution is slowly added to the reactor containing 5mL of acid solution (referred to as solution B), and the two kinds of solutions appear to be stratified in the reactor. Small solution B. The reaction kettle was sealed, and slowly placed in an oven at 160° C. for 20 h. After the reactor was cooled to room temperature, the product was obtained between the two-phase interface of solution A and solution B. After filtering, washing with water and drying, a two-dimensional carbon film-coated sea urchin-like titanium dioxide composite material is obtained.
[0018] Implementation Case 3
[0019] Firstly, 0.1g of P123 was added to 10mL of n-hexane, stirred at 40°C for 2h, then 1mmol of tetrabutyl t...
