Embodiment 1
[0043] At room temperature, dissolve 0.75g of cetyltrimethylammonium bromide in 32ml of isopropanol solution, stir until completely dissolved, add 5g of tetra-n-butyl titanate, 1ml of glacial acetic acid, and stir for 0.5h A uniform light yellow solution A is formed; add 1.5ml of deionized water to 2ml of isopropanol to form a dropwise solution B; slowly drop B into solution A, stir and react at 30°C in a closed state for a certain period of time to obtain a uniform milky white TiO 2 Gel; aged for more than 48h, the obtained mesoporous TiO 2 The precursor gel was placed in a petri dish and dried at 100 °C, as image 3 As shown, the xerogel was calcined at 400 °C for 3 h to obtain white mesoporous TiO 2 Powder, its SEM picture is as follows figure 1 -b shown.
[0044] Then TiO 2 Immersed in a nickel nitrate solution with a concentration of 0.2wt%, dried the impregnated catalyst at 100°C for 2h, and calcined at 500°C for 5h to obtain Ni-mesoporous TiO with a pore size of 5....
Embodiment 2
[0046] Such as image 3 Shown, with embodiment 1, difference is to control mesoporous TiO 2 The calcination temperature of the precursor gel was 350°C to obtain 4.6nm pore size Ni-mesoporous TiO 2 Photothermal catalyst, its SEM picture is as follows figure 1 -a shown.
Embodiment 3
[0048] Such as image 3 Shown, with embodiment 1, difference is to control mesoporous TiO 2 The calcination temperature of the precursor gel was 450°C to obtain 8.4nm pore size Ni-mesoporous TiO 2 Photothermal catalyst, its SEM picture is as follows figure 1 -d shown.
