Application of covalent organic frameworks and metal–organic frameworks nanomaterials in organic/inorganic pollutants removal from solutions through sorption-catalysis strategies

Carbon Research, Journal Year: 2023, Volume and Issue: 2(1)

Published: Feb. 9, 2023

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.

Abstract Biochar and biochar-based materials have been studied extensively in multidisciplinary areas because of their outstanding physicochemical properties. In this review article, biochar the removal environmental pollutants, hydrogen generation carbon dioxide capture were summarized compared. The interaction mechanisms discussed from experimental results characterization analysis. high porous structures, active surface sites, (co)doping single metals/nonmetals, incorporation metal oxides or other improved activity applications. However, there are still some challenges such as: (1) fact that H 2 with selectivity produced syngas to meet real application requirement industrial is main challenge production; (2) selective CO stability, adsorption capacity recyclability at low-cost should be considered focused on; (3) sorption-(photo)degradation organic chemicals; (4) sorption-reduction-extraction/solidification metals/radionuclides efficient methods for elimination pollutants. end, perspectives, possible techniques materials’ future described.

Constructing coconut shell biochar/MXenes composites through self-assembly strategy to enhance U(VI) and Cs(I) immobilization capability

Biochar, Journal Year: 2023, Volume and Issue: 5(1)

Published: June 1, 2023

Abstract Herein, a biochar-based composite (Ti 3 C 2 T x @biochar-PDA/PEI) was constructed by decorating Ti and polydopamine on coconut shell biochar via electrostatic self-assembly method. Different characterization techniques were applied to explore the structure, morphology composition of sorbents. It found that higher porosity diverse functional groups conducive for @biochar-PDA/PEI capture radionuclides, water environmental conditions made great contribution adsorption process. The process removing U(VI)/Cs(I) well complied with Langmuir isotherm Pseudo-second-order equations, which indicated single layer chemical occurred solid liquid interface. Meanwhile, this produced exhibited superior removal performance under complex co-existing ion environment, maximum amounts U(VI) Cs(I) reached up 239.7 40.3 mg g −1 . Impressively, adsorbent still good after three cycles regeneration. spectral analysis DFT calculation demonstrated might be process, while should exchange or attraction. This study potential application as an effective remediation strategy radioactive wastewater cleanup. Graphical

Abstract With rapid global industrialization, environmental pollution has become one of the major problems human society. Photocatalysis can be applied to solve problem by using inexhaustible solar energy. As a novel two-dimensional material, graphite carbon nitride (g-C 3 N 4 ) been widely in many photocatalytic reactions. However, terms its practical applications, g-C still limitations, including poor photoexcited charge separation, limited range visible light absorption, and low surface areas. Hence, current research on mainly focuses improving performance.
