Degradation of tetracycline by nitrogen-doped biochar as a peroxydisulfate activator: Nitrogen doping pattern and non-radical mechanism

Sustainable Horizons, Journal Year: 2024, Volume and Issue: 10, P. 100091 - 100091

Recently, nitrogen-doped biochar (NBC) has attracted a great deal of attention in the field advanced oxidation processes (AOPs) for treatment various pollutants. However, effect nitrogen doping method on catalyst efficiency NBC not been fully understood. In this study, was prepared using two different methods: carbonization urea mixed with maize straw (NBC1) and pristine obtained from (NBC2). Catalytic degradation tetracycline (TC) presence peroxydisulfate (PDS) examined, process factors reaction mechanism were explored. Characterizations revealed that NBC1 had higher content (6.86 %) carbon defects compared to NBC2. Under optimum conditions 0.4 g L−1, PDS 3 mM, TC 15 mg solution pH 4.6, reached over 86.55 % within 120 min, which than NBC2 (57.10 %). Moreover, catalytic system showed resistance anions dissolved organic matter, by remained 82.47 after secondary carbonization. Radical quenching electron spin resonance spectroscopy verified co-existence ·OH, SO4·−, O2·−, 1O2 system, made significant contribution degradation. More importantly, quantitative structure-activity relationships (QSAR) density functional theory (DFT) calculations displayed graphitic N, as primary active site, played an important role activation This work provides evidence preparation efficient biochar, elucidation mechanism, its feasibility wastewater treatment.

Metal oxides-based photocatalyst for the efficient degradation of organic pollutants for a sustainable environment: a review

Nanoscale Advances, Journal Year: 2024, Volume and Issue: 6(19), P. 4781 - 4803

Published: Jan. 1, 2024

Photocatalytic degradation is a highly efficient technique for eliminating organic pollutants such as antibiotics, dyes, toluene, nitrobenzene, cyclohexane, and refinery oil from the environment. The effects of operating conditions, concentrations contaminants catalysts, their impact on rate deterioration are key focuses this review. This method utilizes light-activated semiconductor catalysts to generate reactive oxygen species that break down contaminants. Modified photocatalysts, metal oxides, doped composite materials, enhance effectiveness photocatalytic by improving light absorption charge separation. Furthermore, operational conditions pH, temperature, intensity also play crucial role in enhancing process. results indicated both high pollutant catalyst improve up threshold, beyond which no significant benefits observed. optimal were found significantly efficiency, with marked increase rates under ideal settings. Antibiotics dyes generally follow intricate pathways, resulting breakdown these substances into smaller, less detrimental compounds. On other hand, hydrocarbons toluene along may necessitate many stages achieve complete mineralization. Several factors affect efficiency characteristics photocatalyst, concentration, intensity, existence co-catalysts. approach offers sustainable alternative minimizing amount present environment, contributing cleaner air water. hence holds tremendous potential remediation
