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.

A critical review of biochar-based nitrogen fertilizers and their effects on crop production and the environment

Biochar, Journal Year: 2022, Volume and Issue: 4(1)

Published: June 13, 2022

Abstract Globally, nitrogen (N) fertilizer demand is expected to reach 112 million tonnes support food production for about 8 billion people. However, more than half of the N lost environment with impacts on air, water and soil quality, biodiversity. Importantly, loss contributes greenhouse gas emissions climate change. Nevertheless, where application limited, severe depletion fertility has become a major constraint sustainable agriculture. To address issues low use efficiency (NUE), biochar-based fertilizers (BBNFs) have been developed reduce off-site maximize crop uptake. These products are generally made through physical mixing biochar or via coating chemical such as prilled urea biochar. This review aims describe manufacturing processes BBNFs, critically assess effects properties, yield pathways. Graphical
