Embodiment 1
[0026] 1. Dry the discarded cigarette butts at 40°C for 12 hours;
[0027] 2. Put the dried cigarette butts into the tube furnace, feed nitrogen gas for 10 minutes, set the temperature of the tube furnace to 500°C, and anneal for 2 hours to obtain carbon fibers;
[0028] 3. Soak the carbon fiber obtained above in cadmium acetate aqueous solution for 30 seconds, then soak it in sodium sulfide aqueous solution for another 30 seconds after natural air drying, put it in a tube furnace after air drying, and calcinate at 400°C under a nitrogen atmosphere, and then cool to room temperature to obtain Carbon fibers loaded with cadmium sulfide particles.
