Contact-electro-catalysis (CEC) is a bridging concept between contact-electrification effect (also known as triboelectricity) and mechanochemistry. It was first proposed in 2022 by using dielectric materials (e.g., FEP) to catalyze the degradation of methyl orange (MO) aqueous solution. The definition of CEC refers to a process that exploits the electron transfer during contact-electrification (CE) to promote chemical reactions. The solid to be used in CEC involves pristine polymers (FEP, PTFE), inorganics (SiO2), and matrix composites. The energy source of CEC is mechanical stimuli such as ultrasonication and ball milling. The application fields of CEC include organic pollutants degradation, direct synthesis of H2O2, recycle of spent lithium-ion batteries (LIBs), and continuous synthesis of ammonia.
