Fabrication of Efficient Na, B, and O Codoped g-C₃N₄/Polypyrrole-Carbon Black 3D Beads for Expeditious Degradation of Tetracycline via Percarbonate Activation

Industrial & Engineering Chemistry Research, Journal Year: 2024, Volume and Issue: 63(6), P. 2605 - 2618

Published: Feb. 5, 2024

A hybrid Na, B, and O codoped g-C3N4/polypyrrole carbon black (CCNP) hydrogel is prepared via an in situ cross-linking method for percarbonate activation under visible light irradiation. The structural, morphological, optical characterizations proved the tuned bandgap, enriched utilization of light, minimum recombination ratio, higher separation efficiency. CCNP hydrogels could easily activate leading to abundant production reactive radicals, which aids degradation tetracycline wastewater. About 96% was degraded 15 min at its natural pH. superoxide, carbonate, hydroxyl radicals were important radical species degradation. also exhibited high photostability reusability up six cycles. pathway given a special focus, mechanism highlighted. This study provides new strategy boosting performance g-C3N4-based catalysts wastewater remediation.

Enhanced Generation and Effective Utilization of Cr(V) for Simultaneous Removal of Coexisting Pollutants via MOF@COF Photocatalysts

ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: 4(4), P. 870 - 881

Published: Jan. 16, 2024

Simultaneous removal of coexisting aqueous pollutants is urgently needed in the face higher demands for wastewater purification. Using pollutant intermediates with strong oxidizing ability to degrade other a novel, energy-saving, and environmentally friendly way. Increased generation effective utilization these are vital boost decontamination performance. Here, we fabricated core–shell MOF@COF (MIL-125@PC–COF) heterojunction photocatalyst synergistic Cr(VI) organic tetracycline (TC). The efficiency TC coexistence system was increased by 2.1- 1.1-fold compared that single-pollutant system, respectively. unique structure composite photocatalysts can hinder recombination photogenerated electrons holes, thus promoting production Cr(V) from reduction. Quenching tests, situ variable-temperature electron paramagnetic resonance (EPR) analysis, UV–vis absorbance verified its positive contribution degradation. mechanism key role dual-pollutant were clarified.
