g-C3N4-based photocatalysts for organic pollutant removal: a critical review

Carbon Research, Год журнала: 2023, Номер 2(1)

Опубликована: Апрель 6, 2023

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. In this review, we summarize various methods improve ’s absorption photo-induced transfer, vacancy engineering, morphology control, heteroatom doping, forming heterostructure. The applications derivatives photodegradation organic pollutants are also discussed detail. Finally, challenges future directions photocatalysts summarized promote their applications. Graphical

A comprehensive and global evaluation of residual antibiotics in agricultural soils: Accumulation, potential ecological risks, and attenuation strategies

Ecotoxicology and Environmental Safety, Год журнала: 2023, Номер 262, С. 115175 - 115175

Опубликована: Июнь 26, 2023

The occurrence of antibiotics in agricultural soils has raised concerns due to their potential risks ecosystems and human health. However, a comprehensive understanding antibiotic accumulation, distribution, terrestrial on global scale is still limited. Therefore, this study, we evaluated the accumulation soil microorganisms plants, highlighted driving factors based 134 peer-reviewed studies (between 2000 2022). results indicated that 56 types were detected at least once with concentrations ranging from undetectable over 7000 µg/kg. Doxycycline, tylosin, sulfamethoxazole, enrofloxacin, belonging tetracyclines, macrolides, sulfonamides, fluoroquinolones, respectively, most accumulated soil. TCs, SAs, FQs was found pose greater (average 29.3%, 15.4%, 21.8%) plants (42.4%, 26.0%, 38.7%) than other antibiotics. East China identified as hot spot for contamination high levels concentration ecological risk plants. Antibiotic be higher vegetable fields (245.5 µg/kg) orchards (212.4 compared croplands (137.2 µg/kg). Furthermore, direct land application manure resulted compost fertilization. level decreased increasing pH organic matter content, attributed decreasing adsorption enhancing degradation In conclusion, study highlights need further research impacts function interaction mechanisms. Additionally, whole-chain approach, consisting consumption reduction, management strategies, remediation technology contaminated antibiotics, needed eliminate environmental sustainable green agriculture.

Synthetic organic dyes, which are resistant to biodegradation, pose a notable health risk, potentially leading cancer and respiratory infections. Researchers have addressed this concern by exploring physicochemical methods remove dyes from wastewater. A particularly promising solution involves modified biochar adsorbents, demonstrate high efficiency in dye removal. Biochar, charcoal-like material derived biomass pyrolysis, offers advantages such as low cost, eco-friendliness, reusability. Beyond its role sustainable soil remediation, proves effective removing wastewater after undergoing physical or chemical modification. Acid–base activation metal–heteroatom impregnation enhances biochar's adsorption capacity. This comprehensive review examines the attributes of biochar, common for production modification, impacts raw materials, pyrolysis temperature, heating rate residence time.
