Abstract
In general, methyl orange (MO) can be degraded by an
electrocatalytic oxidation process driven by a power source due to
the generation of superoxidative hydroxyl radical on the anode. Here,
we report a hybrid energy cell that is used for a self-powered electrocatalytic
process for the degradation of MO without using an external power
source. The hybrid energy cell can simultaneously or individually
harvest mechanical and thermal energies. The mechanical energy was
harvested by the triboelectric nanogenerator (TENG) fabricated at
the top by using a flexible polydimethysiloxane (PDMS) nanowire array
with diameters of about 200 nm. A pyroelectric nanogenerator (PENG)
was fabricated below the TENG to harvest thermal energy. The power
output of the device can be directly used for electrodegradation of
MO, demonstrating a self-powered electrocatalytic oxidation process
