Sources, environmental fate, and impacts of microplastic contamination in agricultural soils: A comprehensive review.

The pervasive presence of microplastics has emerged as a pressing global environmental concern, posing threats to food security and human health upon infiltrating agricultural soils. These microplastics primarily originate from agricultural activities, including fertilizer inputs, compost-based soil remediation, irrigation, and atmospheric deposition. Their remarkable durability and resistance to biodegradation contribute to their persistent presence in the environment.

Promoted Hydrogen Peroxide Production from Pure Water on g-CN with Nitrogen Defects Constructed through Solvent-Precursor Interactions: Exploring a Complex Story in Piezo-Photocatalysis.

Hydrogen peroxide (HO) production via oxygen (O) reduction reaction (ORR) in pure water (HO) through graphitic carbon nitrides (g-CN)-based piezo-photocatalysts is an exciting approach in many current studies. However, the low Lewis-acid properties of g-CN limited the catalytic performance because of the low O adsorption efficacy. To overcome this challenge, the interaction of g-CN precursors with various solvents are utilized to synthesize g-CN, possessing multiple nitrogen-vacant species via thermal shocking polymerization.

Simultaneously Utilizing Excited Holes and Electrons for Piezoelectric-Enhanced Photoproduction of HO from S-Scheme 2D S-Doped VO/g-CN Nanostructures.

2D/2D step-scheme (S-scheme) piezo-photocatalysts for the production of fine chemicals, such as hydrogen peroxide (HO), have attracted significant attention of global scientists owing to the efficiency in utilizing surface piezoelectric effects from 2D materials to overcome rapid charge recombination in photocatalytic processes. In this research, we reported the fabrication of 2D S-doped VO deposited on 2D g-CN to produce HO via the piezo-photocatalytic process with high production yields at 20.19 mmol g h, which was 1.

Rapid fabrication of MgO@g-CN heterojunctions for photocatalytic nitric oxide removal.

Nitric oxide (NO) is an air pollutant impacting the environment, human health, and other biotas. Among the technologies to treat NO pollution, photocatalytic oxidation under visible light is considered an effective means. This study describes photocatalytic oxidation to degrade NO under visible light with the support of a photocatalyst.

Revisiting the Key Optical and Electrical Characteristics in Reporting the Photocatalysis of Semiconductors.

Photocatalysis has been studied and considered as a green and practical approach in addressing environmental pollution. However, factors that affect photocatalytic performance have not been systematically studied. In this work, we have presented a comprehensive roadmap for characterizing, interpreting, and reporting semiconductors' electrical and optical properties through routinely used techniques such as diffuse reflectance spectroscopy, electrochemical techniques (Mott-Schottky plots), photoluminescence, X-ray photoelectron spectroscopy, and ultraviolet photoelectron spectroscopy in the context of photocatalysis.
