| abstract | SnO (stannic oxide) 2 /α～Bi 2 O 3 /β～Bi 2 O 3 The composite material and the preparation method thereof comprise the following steps: (1) accurately weighing 0.05M SnCl by using an analytical balance 4 ·5H 2 O and 0.025M Bi (NO) 3 ) 3 ·5H 2 Placing the O in a mortar, grinding for 2 minutes, adding 5-15 wt% of polyvinyl alcohol-350, and grinding for 5 minutes; (2) adding 11g of NaOH, and fully grinding for 5 minutes to obtain a precursor; (3) placing the precursor in a high-temperature oven at 150 ℃ for reaction for 1.5 h; (4) taking out, naturally cooling, washing with deionized water, ethanol and vacuum suction filter for several times until no Cl is detected ‑ (ii) a (5) The obtained product is put into a beaker, dried at the temperature of 103-105 ℃ and then put into a muffle furnace for calcination for 2 h. The composite material synthesized by the method has wide photoresponse range, high photocatalytic efficiency and high photocatalytic efficiency, and the light absorption boundary reaches 725nm, and the photocatalytic test shows that: under the irradiation of a metal halide lamp, the rhodamine B can be decolorized for 99% in about 5 minutes, and the decolorization rate still reaches 90% after 10 cycles. |
