Summary: In the p-n junction of Co/Cu-ZIF/Fe2O3, electrons flow from n-type Fe2O3 to p-type bimetallic Co/Cu-ZIF, resulting in band bending and an inner electric field. Density function theory calculations showed that this change in electronic properties could enhance water oxidation performance. Experiments demonstrated that the Co/Cu-ZIF(1/1)/Fe2O3 heterojunction achieved a low overpotential and small Tafel slope, outperforming monometallic Co-ZIF and FC substrate. Furthermore, the p-n junction promoted the electrocatalytic degradation of 4-nitrophenol with high removal rate and low energy consumption. Therefore, MOFs-based p-n junctions with electron configuration modulation hold promise for boosting electrochemical water oxidation.

Summary: The removal of p-nitrophenol (PNP) from wastewater was evaluated using different carbon materials and their nitrogen-doped counterparts in the activated persulfate process. The study found that the specific surface area of carbon materials influenced the adsorption process, while the mesoporous area influenced the activation process. Nitrogen groups on the surface of the samples accelerated the degradation and mineralization of PNP. The stability of the nitrogen-doped carbon materials was evaluated, and the Fe/XGM sample showed stable performance without leaching of iron. The activated persulfate process achieved complete PNP oxidation and TOC removal of around 96%, making it more attractive than the Fenton method.

Summary: Fe3O4 nanoparticles decorated on cellulose aerogel (CA) from banana stems (Fe3O4@CA) were synthesized and applied for the Fenton degradation of p-nitrophenol (PNP). The Fe3O4@CA samples were characterized, and the effects of Fe3O4 content and H2O2 concentration on PNP treatment efficiency were investigated. The optimized Fe3O4@CA catalyst content loaded on CA was 0.40 g/g, and the H2O2 concentration was 5.0 g/L. The removal efficiency of Fe3O4@CA reached 87.92% in 100 mins, following the pseudo-first kinetic model with a reaction rate constant of 0.0301 min-1. This study provides a method for creating environmentally friendly catalytic material, offering potential applications in green chemical engineering.

Summary: Recently, biochar has been found to degrade the common organic environmental pollutant p-nitrophenol (PNP). However, the role of biochar-derived dissolved organic matter (BDOM) in PNP degradation remains unclear. In this study, two BDOM samples were prepared and their PNP degradation performance was analyzed. The study found that BDOM5 (prepared at 500 degrees C) showed a higher PNP degradation ratio compared to BDOM7 (prepared at 700 degrees C), and both oxidative and reductive processes contributed to the PNP degradation by BDOM. The higher PNP removal of BDOM5 was attributed to its higher electron exchange capacity, and hydroxyl radicals (•OH) played a critical role in the oxidative degradation process of PNP by BDOM. These findings may contribute to a better understanding of PNP degradation by BDOM and the environmental impact of biochar application.

Summary: We reported a novel electrochemical sensor for the indirect determination of cyanuric acid (CA) using the complex formation between CA and melamine (MEL) for the first time. The sensor utilized the electrochemical conversion of MEL to electroactive polymelamine, with the decline in current intensity upon the addition of CA serving as the sensor response. A calibration curve was constructed using square wave voltammetry, with a limit of detection of 80.28 mu mol L-1. The proposed method showed excellent recovery range (91.2-101.0%) for real sample analysis.
