Problems solved by technology

The preparation process is relatively cumbersome, and the reaction requires a high-temperature environment. The most important thing is that there are safety hazards in the process; in addition, this method only prepares composite powder materials, which does not address the shortcomings of pure powder materials in photocatalysis. solution, which greatly limits the properties and applications of the material

Embodiment 1

[0049] First, in this experiment, tin tetrachloride (SnCl 4 ·5H 2 O) and sodium hydroxide (NaOH) as reaction source materials to prepare SnO on a flexible substrate carbon cloth 2 . The specific operation process is as follows: use an electronic balance to weigh a certain amount of tin tetrachloride (SnCl 4 ·5H 2 O) and sodium hydroxide (NaOH), respectively configure 0.04mol / L tin tetrachloride solution and 0.56mol / L NaOH solution, and then slowly titrate the prepared NaOH solution into the tin tetrachloride solution to make it Mix well and finally form a stable and uniform precursor solution. Slowly pour the solution into a 50ml autoclave containing carbon cloth, place it in an oven, and react at 200°C for 16 hours. After the reaction is over, take out the carbon cloth and wash it with deionized water several times. Arrange the carbon to dry at 60℃ to obtain SnO 2 Coated carbon fiber composite material.
