[18][19][20][21] Recently, MXene (Ti 3 C 2 T x ) has been widely used in triboelectric materials and TENG applications due to its high electronegativity, good conductivity, and high charge capture ability, which greatly improves the output performance of TENG. [22] Additionally, spherical network structure is considered as a promising structure with high specific surface area and good chemical stability.…”

Improving Wastewater Treatment by Triboelectric-Photo/Electric Coupling Effect

“…If the hydropower and other neglected fragment energy during wastewater treatment can be collected and utilized in electrochemical systems, the total energy input for wastewater treatment can be significantly reduced. The triboelectric nanogenerator (TENG), a mechanical-to-electrical energy conversion device, was invented by Wang’s research group, which combines contact electrification and electrostatic induction. − Based on their flexible design (e.g., cross-linked, multilayer-linked, and grating-structured), TENGs have been rapidly developed and widely used. − TENG devices have a contact electrification effect and the advantages of being lightweight, cost-effective and easy to expand, , which allows the fabrication of self-powered environmental protection systems. − Recently, TENGs have been driven by various environmentally friendly energy sources, such as water wave, wind, infrastructural vibration, and human body motions, to produce useful and cost-effective electrical energy. − Electrochemical water treatment systems were combined with TENGS for water splitting, detection, removal of heavy-metal ions, and pollutant degradation. − Figure shows the potential energies of the water, wind, and acoustic energy sources generated in the wastewater treatment facilities (e.g., pump house, blower room, oxidation ditch, ultrafiltration process, sedimentation basin, aeration tank, anaerobic reactor), which can be utilized by TENGs.…”

“…The TENG-photo/electric coupling applied bias potential prevented the recombination of electrons and holes produced by photocatalysis, which improved the efficiency of photocatalytic oxidation. The coupling of TENGs and photo/electric catalysis includes anodic oxidation, electro-Fenton and electroassisted photocatalysis, and photoassisted electrocatalysis. , In contrast to adsorption, ion exchange and other technologies in traditional wastewater treatment, TENG-photo/electrical coupling is not selective for certain contaminants and reuses materials, which reduces the cost of treatment. , Particularly with regard to antibiotic contaminants, the free radicals produced by TENG-photo/electric coupling have strong oxidation potentials . The electricity generation by TENGs enhances photocatalytic oxidation to remove pollutants, making this technology feasible for broad applications.…”
