A condensation polymer (urea-formaldehyde resin) passivated ZnO nanoparticles were used as an efficient photocatalyst for methyl blue degradation in the presence of HO involving a Fenton-like reaction. The formation of OH˙ radicals were attributed to the pivotal factor for the degradation process. The method was easy and recyclable. The dose of photocatalyst, initial dye concentration, pH variation, variations of the composition of the photocatalyst, and the effect of scavengers were gauged. The degraded product was highly fluorescent and fluorometric detection of HO was achieved along with a colorimetric recognition pathway. No other dye could be degraded under similar experimental conditions, implying the novel utility of methyl blue for environmental remediation.

The electrocatalytic conversion of oxygen to hydrogen peroxide offers a promising pathway for sustainable energy production. However, the development of catalysts that are highly active, stable, and cost-effective for hydrogen peroxide synthesis remains a significant challenge. In this study, a novel polyacid-based metal-organic coordination compound (Cu-PW) was synthesized using a hydrothermal approach.

Membrane technology is an important component of resource recovery. Covalent organic frameworks (COFs) with inherent long-range ordered structure and permanent porosity are ideal materials for fabricating advanced membrane. Zwitterionic COFs have unique features beyond single ionic COFs containing anions or cations.

Controlling the redox ability is crucial for optimizing catalytic processes in clean energy, environmental protection, and CO reduction, as it directly influences the reaction efficiency and electron transfer rates, driving sustainable and effective outcomes. Here, we report the plasma-electrified synthesis of composition-controlled FeAu bimetallic nanoparticles, specifically engineered to enhance the redox catalytic performance through precise tuning of their chemical states. Utilizing atmospheric-pressure microplasmas, FeAu nanoparticles were synthesized under ambient conditions without the need for reducing agents or organic solvents, thereby providing a green and sustainable approach.
