Embodiment 1
[0018] (1) Preparation of titanium carbide: 1 g of titanium aluminum carbide was added to 30 mL of 40% hydrofluoric acid, and etched in an oil bath at 50 °C for 24 h to obtain accordion-shaped aluminum carbide (Ti 3 C 2 ).
[0019] (2) Preparation of titanium carbide / indium zinc sulfide composite visible light catalyst: First, mix 10 mmol sulfur powder with 10 mL oleic acid, take an oil bath at 115 °C for 20 min, heat it up to 150 °C, and continue the oil bath for 10-20 min. A 1 mol / L OA-S solution was obtained. Then, 1 mmol of zinc acetate, 2 mmol of indium trichloride, 10 mL of oleylamine and 4 g of tri-n-zinc-based phosphine oxide were added to the three-necked round-bottomed flask. ℃, 4 mL of OA-S solution was rapidly injected after 5 min, 20-30 mL of ethanol was injected immediately after 30 min, cooled to room temperature, and centrifuged at 9000 r / min for 2 min to obtain indium zinc sulfide nanoparticles, which were then dissolved in trichloride In methane, 60 mg of ...
