Summary: The Pb-free Cs2AgBiBr6 double perovskite nanoplates and their heterostructure with Cu-loaded reduced graphene oxide exhibit significant photocatalytic activity and high quantum efficiency for gas-phase CO2 reduction. The enhanced performance compared to traditional Pb-based perovskites is attributed to improved charge separation, suppressed electron-hole recombination, and extended visible light absorption.

Summary: Textile effluents are harmful to human health and the environment. To mitigate these hazards, researchers have been developing environmentally friendly technologies to degrade synthetic dyes. This study prepared a Montmorillonite (MMT) supported BiVO4 nanocomposite using the sol-gel method for photocatalytic degradation of Brilliant Red 80 dye. The composite showed a narrow bandgap and strong light absorption in the visible range, resulting in significantly higher degradation efficiency compared to conventional BiVO4.

Summary: The deterioration of water systems necessitates new wastewater treatment technologies for environmental protection. Conventional treatments are ineffective against emerging contaminants and may produce toxic byproducts. Heterogeneous photocatalytic ozonation shows promise for organic compound degradation. Studies suggest that photocatalytic ozonation can efficiently remove organic compounds without increasing effluent toxicity. Future research should focus on comprehensive toxicity assessments and explore immobilized catalysts and energy efficient radiation sources for industrial applications.

Summary: A Fe3O4@L-arginine magnetic nanoparticle was synthesized and used to adsorb humic acid from aqueous solution. The results showed that increasing the adsorbent dose, contact time, and temperature improved the efficiency of humic acid removal, while increasing the initial concentration of humic acid, ionic strength, and pH decreased the efficiency of removal. Under optimal conditions, the highest removal efficiency of humic acid was 67.23% at a 0.5 g/L adsorbent dose and 96.4% at a 2 g/L adsorbent dose. The adsorption of humic acid on Fe3O4@L-arginine followed Langmuir isotherm and pseudo-second-order kinetics.

A high-performance liquid chromatography method was developed to identify the pesticides simultaneously. Quadratic models were developed to investigate the effects of operating parameters and predict the degradation efficiencies. The maximum degradation efficiencies obtained were 99.7%, 100%, and 100% for fenitrothion, trifluralin, and chlorothalonil, respectively.

Summary: Non-thermal plasma (NTP) is a novel oxidation method for water and wastewater treatment, involving the interaction among oxidative species, ultraviolet light, and synthetic organic pollutants (SOPs). Previous reviews have mainly focused on the chemical interaction, performance efficiency, and environmental applications of NTP, neglecting the assessment of energy yield as a crucial determinant. This comprehensive review summarizes recent research findings and compares different systems. Factors influencing NTP oxidation systems, including voltage, frequency, initial pollutant concentration, output power, pH, conductivity, discharge time, and removal efficiency, are discussed. The coupling of NTP with catalytic processes can significantly improve performance and energy yield, with the catalytic NTP technique showing synergistic effects up to 600 times greater.
