Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Imidazolium Modified UiO‐67 Metal‐Organic Frameworks for CO2 Adsorption

European Journal of Inorganic Chemistry, EarlyView.
CO2 sorption in UiO‐67 and its imidazolium‐functionalized derivatives is examined with emphasis on the role of different counterions. Structural characterization and spectroscopic studies provide insight into how functionalization affects pore environments and CO2 interactions.

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Effect of Tunnel Ventilation on Hydrogen Dispersion From Leaks in Hydrogen Fuel Cell Trucks

Energy Science &Engineering, Volume 14, Issue 8, Page 3608-3624, August 2026.
This study investigates hydrogen leakage scenarios involving hydrogen fuel cell trucks within tunnels. Using computational fluid dynamics methods, it explores the distribution characteristics of hydrogen concentrations and the efficiency of ventilation under different forced ventilation conditions. ABSTRACT The widespread adoption of hydrogen fuel cell
