Step 7: the Zn of 0.3mmol is taken0.2Cd0.8S powder is added in mixed solution D, and magnetic agitation forms mixed solution E；
Step 8: mixed solution E being added in the liner of polytetrafluoroethylene (PTFE), and control packing ratio is 40%, is reacted at 180 DEG C
20h；
Step 9: to after the reaction was completed, distinguish centrifuge washing 5 times through deionized water and ethyl alcohol, in 70 DEG C of vacuum drying 10h
By grinding up to Zn0.2Cd0.8S/rGO material powder.
