A niobium (Nb) mesh electrode was coated with boron-doped diamond (BDD) using chemical vapor deposition in a custom-built hot-filament reactor. The BDD-functionalized mesh was tested in a zero-gap electrolysis configuration and evaluated for the anodic formation of HO by selective oxidation of water, including the analysis of the effects on Faradaic efficiency towards HO (FEH2O2) induced by pulsed electrolysis. A low electrolyte flow rate (V⋅) was found to result in a relatively high concentration of HO in single-pass electrolysis experiments.

Light interacts with gas bubbles in various ways, potentially leading to photon losses in gas-liquid photochemical applications. Given that light is a valuable 'reagent', understanding these losses is crucial for optimizing reactor efficiency. In this study, we address the challenge of quantifying these interactions by implementing a method that separately determines the photon flux and utilizes actinometric experiments to determine the effective optical path length, a key descriptor of photon absorption.

The pulp and paper industry, a major global sector, supports economies and jobs while contributing to various products. While providing valuable products, and despite Best Available Techniques (BAT) being used, managing wastewater effectively remains a key area for developing technologies and alternatives for environmental protection. Activated sludge (AS) systems are commonly used for effluent treatment, where microorganisms composition influences reactor efficiency.

Defluorination reactions are increasingly vital due to the extensive use of organofluorine compounds with robust carbon-fluorine (C-F) bonds; particularly, the efficient defluorination of widespread and persistent per- and polyfluoroalkyl substances under mild conditions is crucial due to their accumulation in the environment and human body. Herein, we demonstrate that surface-modified silicate of pronounced proton affinity can confine active hydrogen (•H) onto nanoscale zerovalent iron (nZVI) by withdrawing electrons from nZVI to react with bound protons, generating confined active hydrogen (•H) for efficient defluorination under ambient conditions. The exposed silicon cation (Si) of silicate functions as a Lewis acid site to activate the C-F bond by forming Si.
