A method for electrogenesis, the method comprising:
- a) sonicating a PTFE using ultrasonic waves under a frequency of 20 kHz to 15 megahertz;
- b) connecting a positive electrode and a negative electrode to two opposite surfaces of the PTFE sonicated in a), respectively;
- and c) applying an external pressure on the positive electrode and the negative electrode.
A method for wastewater treatment, the method comprising:
- placing a PTFE in a wastewater, and sonicating the PTFE using ultrasonic waves under a frequency of 20 kHz to 15 megahertz, where an oxide and a reducer are produced, and the oxide oxidizes the pollutants and the reducer reduces the pollutants in the wastewater.
