Application of COFs in capture/conversion of CO2 and elimination of organic/inorganic pollutants

Environmental Functional Materials, Journal Year: 2023, Volume and Issue: 2(1), P. 76 - 92

Published: March 1, 2023

Large amounts of various (in)organic pollutants and CO2 are released into the environment with fast development agriculture industry, which results in environmental pollution climate change, thereby causes great threat to human society. The efficient capture conversion critical against greenhouse effect, whereas elimination from is important health ecosystem. COFs (covalent organic frameworks) have attracted multidisciplinary research interests because their outstanding physicochemical properties such as high surface areas, tunable porous structures, abundant active sites functional groups. Herein application conversion, sorption-photocatalytic degradation pollutants, sorption-catalytic reduction-solidification heavy metals/radionuclides were reviewed compared. interaction mechanisms pollutant molecules discussed macroscopic sorption results, microscopic spectroscopy analysis, theoretical calculations. adsorption capacity was mainly related groups sites, photocatalytic activity dominated by •O2− •OH species. exhibited catalytic removal pollutants. However, there still some main challenges real applications: 1) selective low cost reusability; 2) visible light absorption for molecule degradation; 3) target selectivity 4) reduction ability in-situ solidification under complex conditions; 5) extraction radionuclides complicated solutions seawater or salt lake. In end, perspectives difficulties applications described.

Efficient removal of hexavalent chromium from wastewater using a novel magnetic biochar composite adsorbent

Journal of Water Process Engineering, Journal Year: 2024, Volume and Issue: 66, P. 105908 - 105908

Published: Aug. 7, 2024

Hexavalent chromium (Cr(VI)) in wastewater poses serious environmental and ecological risks. A novel Fe3O4-loaded magnetic biochar (MBC) using Acacia falcata leaf powder was synthesized via one-step hydrothermal carbonization for efficient Cr(VI) removal. FESEM images revealed porous, irregular structures, EDS analysis confirmed Fe, O, C, Cr presence, validating adsorption. XRD indicated a lattice parameter of 0.8407 nm, characteristic magnetite nanoparticles, with an average crystallite size 11.29 nm. MBC exhibited superparamagnetic behavior facilitating easy separation. The deconvolution XPS spectra distinct peaks at 575.6 585.7 eV, corresponding to Cr(III), 577.3 587.8 Cr(VI), thereby confirming the dual roles reduction Batch adsorption followed pseudo-second-order Hill models, highlighting physisorption mechanisms.
