Abstract With the fast development of agriculture, industrialization and urbanization, large amounts different (in)organic pollutants are inevitably discharged into ecosystems. The efficient decontamination contaminants is crucial to human health ecosystem pollution remediation. Covalent organic frameworks (COFs) metal–organic (MOFs) have attracted multidisciplinary research interests because their outstanding physicochemical properties like high stability, surface areas, sorption capacity or catalytic activity. In this review, we summarized recent works about elimination/extraction pollutants, heavy metal ions, radionuclides by MOFs COFs nanomaterials through sorption-catalytic degradation for chemicals reduction-precipitation-extraction metals radionuclides. interactions between COFs/MOFs at molecular level were discussed from density functional theory calculation spectroscopy analysis. was mainly dominated electrostatic attraction, π-π interaction, complexation H-bonding whereas ions attributed complexation, ion exchange, reduction incorporation reactions. porous structures, groups, active sites important ability selectivity. doping co-doping metal/nonmetal, with other materials could change visible light harvest generation/separation electrons/holes (e − /h + ) pairs, thereby enhanced photocatalytic challenges possible application in elimination water described end.

Pioneering Piezoelectric-Driven Atomic Hydrogen for Efficient Dehalogenation of Halogenated Organic Pollutants

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(8), P. 4008 - 4018

Published: Feb. 13, 2024

The electrocatalytic hydrodehalogenation (EHDH) process mediated by atomic hydrogen (H*) is recognized as an efficient method for degrading halogenated organic pollutants (HOPs). However, a significant challenge the excessive energy consumption resulting from recombination of H* to H2 production in EHDH process. In this study, promising strategy was proposed generate piezo-induced H*, without external input or chemical consumption, degradation and dehalogenation HOPs. Specifically, sub-5 nm Ni nanoparticles were subtly dotted on N-doped carbon layer coating BaTiO3 cube, resulted hybrid nanocomposite (Ni-NC@BTO) can effectively break C-X (X = Cl F) bonds under ultrasonic vibration mechanical stirring, demonstrating high piezoelectric driven efficiencies toward various Mechanistic studies revealed that efficiently capture form Ni–H* (Habs) drive lower toxicity intermediates. COMSOL simulations confirmed "chimney effect" interface nanoparticle, which facilitated accumulation H+ enhanced electron transfer formation improving surface charge piezocatalyst strengthening interfacial electric field. Our work introduces environmentally friendly HOPs using independent consumption.
