We report a unique route that creatively harnessed β-cyclodextrin enhanced triboelectrification for self-powered phenol detection as well as electrochemical degradation. A detection sensitivity of 0.01 μM −1 was demonstrated in the sensing range of 10 μM to 100 μM. In addition, β-cyclodextrin enhanced triboelectrification was designed to harvest kinetic impact energy from wastewater waves to electrochemically degrade the phenol in a self-powered manner without using an external power source.
