Utilization of semiconductor photocatalyst materials to degrade pollutants for addressing environmental pollution problems has become a research focus in recent years. In this work, 2D/2D S-scheme crystalline carbon nitride (CCN)/BiOIO3 (BOI) van der Waals heterojunction was successfully constructed effectively enhancing the degradation efficiency antibiotic contaminant. The as-synthesized optimal CCN/BOI-3 sample exhibited highest 80% photo-degradation tetracycline (TC, 20 mg/L) after 120 min visible light irradiation, which significantly higher than that pure CCN and BOI. significant improvement photocatalytic performance is mainly attributed two aspects: (i) can accelerate interface carriers' separation transfer afford sufficient active sites; (ii) elevated redox capacity CCN/BOI, thus providing driving force reaction. pathways TC CCN/BOI composite were investigated detail by liquid chromatography-mass spectrometry (LC-MS) analysis. This work provides design idea development efficient photocatalysts based on heterojunctions.

Polyaniline-derived nitrogen-doped carbon/MoS2 nanocomposites as cathode for efficient hybrid capacitive deionization

Environmental Engineering Research, Journal Year: 2023, Volume and Issue: 29(2), P. 230204 - 0

Published: July 10, 2023

Molybdenum disulfide (MoS2) has become an attractive faradic material for capacitive deionization (CDI) process, but it still suffers from several drawbacks, such as low electrical conductivity, inferior hydrophilicity and easy restacking. Hence, we integrated MoS2 with high nitrogen content carbonized polyaniline (MoS2/CP) intercalation cathode CDI. The disordered entanglement between CP nanosheets enlarged interlayer spacing, improved pore structure surface area which can provide multiple charge transfer routes endow more embedding sites to storage Na+. Mo-N-C bonds improve the conductivity wettability facilitate ions diffusion process well ensure cyclic stability of composites electrode. Moreover, Na+ N-containing functional groups is beneficial forming pseudo-capacitance. Accordingly, MoS2/CP electrode possess a large specific capacitance 99.1 F g-1 at 5 mV s-1, 36% higher than MoS2. hybrid cell AC//MC-2 delivers remarkable desalination capacity (29.14 mg g-1), rapid rate (2.9 min-1) favorable durability 1.2 V in 500 L-1 NaCl solution. superior performance was evaluated based on capacitance-controlled contribution 85.8% diffusion-controlled 14.2%.

Promoting •OH-dominant Fenton-like process over peracetic acid activation by ultrafine FeOx nanoclusters anchored carbonaceous nanosheets

Fundamental Research, Journal Year: 2023, Volume and Issue: unknown

Published: May 1, 2023

Peracetic acid (PAA) has recently been considered a promising oxidant candidate for heterogeneous Fenton-like reactions; however, the main generation and contribution of organic radicals (R-O•) with unsatisfactory oxidation potential compromises wastewater decontamination efficiency. In this study, we demonstrate rational design synthesis ultrafine FeOx nanocluster-anchored carbonaceous nanosheets (UFe-CN) altering PAA activation pathway from R-O• to •OH dominant process via in situ framework collapse carbonization MIL-53(Fe). The constructed UFe-CN/PAA system effectively accelerated refractory micropollutant (e.g., p-nitrophenol (4-NP)) decomposition by enhanced formation (up 65.24 μmol L− 1) under wide pH range (3.0–9.0), outperforming benchmark iron-based catalyst counterparts 4.2–10.8 times. This outstanding catalytic activity UFe-CN is primarily attributed significant improvement electron mitigation, ca. 49 times higher than that its MIL-53(Fe) counterpart, interface catalysis reactions triggered iron species cycling. Furthermore, facilitate adaptive engineering, pollutant removal efficiency could be easily tuned varying several key treatment factors, including initial pH, concentration, dosage. More importantly, excellent practicality was demonstrated systematically evaluating impact water matrix, regeneration capability, Overall, study provides understanding •OH-dominated an effective development paradigm practical application PAA-based oxidation.
