In the natural environment, mechanical energy is widely available as a sustainable and green source. this paper, we successfully convert on ZnO ZnO/Eu2O3 tribocatalysts via friction route. Electrons were transferred across contact interface when catalyst particles polytetrafluoroethylene (PTFE)-sealed magnetic bar rubbed against each other under stirring. At same time, holes left while PTFE absorbed electrons. Similar to photocatalysis, organic pollutants can be effectively oxidized by in valence band of sol-gel catalysts due their strong oxidative ability. The tribocatalytic tests demonstrated that could eliminate analgesics (paracetamol) stirring dark. By controlling quantity rare earth elements (1, 2, 3 mol%), speed, number rods, further enhance performance. addition developing tribocatalysis approach for purification pollutants, work offers potential route converting environmental into chemical energy, which used remediation.

Dichlorvos (2,2-dichlorovinyl dimethyl phosphate, DDVP) is a highly toxic organophosphorus insecticide, and its persistence in air, water, soil poses potential threats to human health ecosystems. Covalent triazine frameworks (CTFs), with their sufficient visible-light harvesting capacity, ameliorated charge separation, exceptional redox ability, have emerged as promising candidates for the photocatalytic degradation of DDVP. Nevertheless, pure CTFs lack effective oxidative active sites, resulting elevated reaction energy barriers during photodegradation In this work, density functional theory (DFT) calculations were employed investigate impact various oxygen-containing acid groups (-COOH, -HSO3, -H2PO3) on DDVP performance. First, simulations structure optical properties modified reveal that induce surface distortion result redshift absorption edge. Subsequently, analysis states, frontier molecular orbitals, electrostatic potential, work function, dipole moment demonstrates enhance CTF polarization, facilitate ameliorate capability. Additionally, free-energy diagram uncovers lower barrier by elevating adsorption activation capability Notably, -H2PO3 presents optimal unique electronic This offers valuable reference development CTF-based photocatalysts applied degrading organophosphate pesticides.
