Embodiment 1
[0022] The preparation method of CoS-Ag-CNFs counter electrode comprises the steps:
[0023] (1) Preparation of CoS;
[0024] Weigh 0.749g CoCl 2 ·6H 2 O with 0.473g CH 3 CSNH 2 , pour them into the reaction kettle, and add 63mL of absolute ethanol into the 90mL polytetrafluoroethylene-lined reaction kettle, then treat the prepared solution with ultrasonic waves in an ultrasonic cleaner for 30min, and after the solution is evenly dissolved, Put the reaction kettle into an electric constant temperature blast drying oven for drying, the drying temperature is 140~160°C, and the drying time is 24 hours; then the reacted solution is repeatedly centrifuged 3 times with a centrifuge, and the gray-black precipitate obtained at last is washed with Dry in a vacuum drying oven at 60°C for 10 hours, the drying temperature is 50-60°C, and the drying time is 10 hours; a gray-black powder is obtained, and then the prepared gray-black powder is stored for later use;
