Embodiment
[0033] 1.1. Preparation of organic dye photocatalyst
[0034] Add 0.5g Na to the 15mL hydrothermal kettle 2 WO 4 ·H 2 O, 0.05g Co(Ac) 2 4H 2 O, 0.2g Na 2 HPO 4 , 150uL ethylenediamine and 4mL deionized water, stirred with a stirrer at room temperature for 10 minutes, continued to add 450uL phosphoric acid and stirred at room temperature for 10 minutes, then put it into a steel reactor jacket and put it into an electric heating oven. The oven was heated to 180°C with the maximum power and kept at 180°C for 3 days, and then the oven was naturally cooled to room temperature to obtain a purple-black solid, crystalline compound 1 (yield: 0.12 g). Na 2 WO 4 ·H 2 O, Co(Ac) 2 4H 2 O, Na 2 HPO 4 , Ethylenediamine (en) is analytically pure, phosphoric acid (H 3 PO 4 ) mass fraction 85%. Compound (H 8 (H 2 en) 6 [Co(H 2 O)Co(P 4 Mo V 6 o 31 ) 2 ]·6H 2 O) is based on (P 4 Mo V 6 o 31 ) 12- (abbreviated as P 4 Mo V 6 ) is the two-dimensional layered struct...
