Fabrication of CdS/ZnCr-LDH heterojunctions with enhanced of tetracycline hydrochloride photocatalytic degradation under visible light

Jichao Zhu et al.

Summary: Water pollution caused by antibiotics is a major issue, and this study aims to use photocatalytic degradation as a green and effective method to remove antibiotics from wastewater. A Z-scheme photocatalyst consisting of CdS and ZnCr-LDH was prepared and evaluated for its performance in degrading tetracycline hydrochloride (TCH) under visible light. The CdS/ZnCr-LDH-5 photocatalyst showed significantly higher removal efficiency for TCH compared to its precursors, with a removal rate of 84.9%. The enhanced degradation efficiency can be attributed to its high redox ability and charge separation efficiency. The study also proposed a possible degradation pathway and Z-scheme degradation mechanism. This work provides new insights for designing heterojunctions with a Z-scheme charge transfer mechanism for effective photocatalytic degradation of antibiotics.

Phosphorus adsorption by functionalized biochar: a review

Dan Luo et al.

Summary: Phosphorus is a crucial element for agricultural production but its non-renewable phosphate ore resources are depleting. Phosphate release from wastewater treatment plants and inefficient crop fertilization causes pollution such as water eutrophication. Therefore, phosphorus recovery from wastewater through biochar adsorption is a promising alternative agricultural phosphorus source. Biochar, with its porous structure, large surface area, abundant surface groups, and high mineral content, can effectively adsorb phosphorus. Additionally, functionalization of biochar can improve its adsorption performance.

Ferroelectric polarization-enhanced photocatalytic performance of heterostructured BaTiO3@TiO2 via interface engineering

Fan Bao-yan et al.

Summary: The study successfully enhanced photocatalytic activity by synthesizing ferroelectric-BaTiO3@photoelectric-TiO2 nanohybrids, with a degradation efficiency 1.7 times higher than pure TiO2 and 7.2 times higher than pure BaTiO3. This improvement is attributed to the synergy effect of photoelectric TiO2, ferroelectric-BaTiO3, and the rationally designed interfacial structure, which promotes the separation and transport of photogenerated charge carriers.

Visible-light-induced NiCo2O4@Co3O4 core/shell heterojunction photocatalysts for efficient removal of organic dyes

Wang Huan-wei et al.

Summary: Visible-light-induced NiCo2O4@Co3O4 core/shell heterojunctions were synthesized via a sol-gel method, showing remarkably enhanced removal rate towards congo red. The excellent performance of NiCo2O4@Co3O4 benefits from the effective separation of photogenerated electron-holes and rapid transfer efficiency of photo-generated charge carriers due to the core/shell architectures. A mechanism of degrading CR to harmless inorganic substances by h(+), center dot O-2(-), and center dot OH during the photocatalytic process was proposed.

An overview on engineering the surface area and porosity of biochar

Lijian Leng et al.

Summary: Surface area and porosity are crucial physical properties of biochar that significantly impact its applications, with biomass composition and pyrolysis temperature being major influencing factors. Activation, particularly through chemical means, is the most effective way to enhance biochar surface area and porosity, while other treatment methods like carbonaceous materials coating and ball milling can also contribute to improvement. Future research should focus on developing treatment technologies to simultaneously enhance the functionality and porous structure of biochar.

Summary: This study enhances the catalytic efficiency of pyrite by pre-reaction with hydrogen peroxide to degrade recalcitrant contaminants. By optimizing factors such as pre-reaction time, hydrogen peroxide concentration, solution pH, and dye concentration, efficient degradation of contaminants using natural pyrite was achieved. Enhanced dye degradation was attributed to the production of hydroxyl radicals facilitated by self-regulation of pH, Fe2+ release, and Fe2+/Fe3+ cycle.

Summary: The synthesis of RMBC composite through co-carbonization of red mud and waste sawdust is effective for Rhodamine B (RhB) oxidation, displaying both adsorption and catalytic effects. The activation of hydrogen peroxide by RMBC shows a low activation energy, and the dominant role of hydroxyl radical in solution for RhB oxidation is verified. The limitations of RMBC for heterogeneous catalysis may be overcome by regulating its alkaline feature, making it a green and sustainable approach for wastewater treatment.
