The widespread production and utilization of plastic products have become ingrained in our society, resulting in a staggering amount of plastic waste, severe environmental challenges, and resource depletion.

Heterogeneous catalytic ozonation (HCO) is a promising advanced oxidation process (AOP) that can effectively degrade recalcitrant organic pollutants; but formation of harmful byproducts should be carefully evaluated.

An integrated strategy combining 3D architecture design and chemical doping holds great promise for enhancing the performance of bio-based engineered carbon materials in environmental applications.

Structure activity relationship, density functional theory, catalytic oxidation and mechanism have become the frontier in MnO₂ environmental catalysis.

C1-gas conversion for sustainable synthesis of fatty acids and ethanol: dynamics of CODH/AdhE1 gene expression with biocatalyst selection.

The {010} facets of the decahedron BiVO₄ were selectively etched using sodium hydroxide solution, while keeping the {110} facets intact. This caused a reversal in the distribution of photogenerated electrons and holes.

As catalytic reactions usually occur on the surface of a catalyst, regulating the catalyst morphology may largely affect the photocatalytic properties.

CuS@Cu-CDs composites as Fenton-like photocatalysts for the degradation of tetracycline.

There are currently no studies on the synthesis and fabrication of ZnO-BiOI and ZnO-WO₃ heterojunctions for the photocatalytic destruction of 2-chlorobiphenyl.

We report the use of the aqueous extract of Peltophorum pterocarpum leaves (PPLE) as a source of relatively cheap and readily accessible reducing- and stabilizing agents for the biosynthesis of silver nanoparticles (AgNPs).

PVP promotes 2H phase SiC generation on 3C-SiC nanosheets to form 2H–3C SiC heterophase junction. The tight interface of 2H–3C phase facilitates the separation of charge carriers, and enhances the photocatalytic reduction of CO₂.

Visible-light-activated photochemical degradation against VOCs in indoor air using TiO₂ nanoparticles encapsulated crystal violet.

Rapid and toxic chemical-free usage reduction technique was developed for synthesizing Cu nanosheets. Cu nanosheets show better degradation efficiency in MB dye as compared to hybrid nanosheets synthesized using conventional expensive techniques.

A TiO₂/Ti₃C₂ MXene aerogel composite was synthesised for photocatalytic degradation of palm oil mill effluent.

A green protocol for the preparation of silver nanoparticles using the leaf, fruit and stem extracts of Hyptis capitata, one of the commonly found plants in the tropics.
