Scalable and Integrated Photocatalytic Reactor Systems for Solar‐to‐Fuel Production: Photoredox and Photoreforming Processes

open access: yesAdvanced Energy Materials, EarlyView.
Solar fuels and other value‐added chemicals derived from light‐driven reactions are highly desirable. Although advanced photoactive materials have been reported, demonstrations of their feasibility in large‐scale production are needed. Hence, strategies and recent efforts in scaling up photocatalytic reactors and integrating them into comprehensive ...

Decoupling Membrane Electrode Assembly Materials Complexity from Fuel Cell Performance through Image‐Based Multiphase and Multiphysics Modelling

open access: yesAdvanced Energy Materials, EarlyView.
A high‐resolution image‐based multiphase and multi‐physics modelling framework is developed to decouple structural changes in the membrane electrode assemblies of high‐temperature proton exchange membrane fuel cells. These changes are then digitally combined to show how morphological defects such as membrane pores, catalyst cracks, and phase migration ...

Alternative Solid‐State Synthesis Route for Highly Fluorinated Disordered Rock‐Salt Cathode Materials for High‐Energy Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work presents a tailored solid‐state route to enhance DRX fluorination and electrochemical performance. Using unconventional precursors, Li6MnO4, MnF2, and TiO2, prevents Mn‐based intermediates, which do not accommodate fluorines, enabling the formation of highly fluorinated DRX with a composition of Li1.23Mn0.40Ti0.37O2−yFy (y = 0.29–0.34 ...

Comparative Analysis of Hydrogen Production and Economic Feasibility: Direct versus Indirect Coupling of Photovoltaic Systems with Electrolyzers

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This article examines the efficiency and cost‐effectiveness of green hydrogen production strategies: direct and indirect, with and without battery. Results show that the indirect configuration with battery yields the highest hydrogen production and profitability. The study discusses technical, energetic, and economic trade‐offs, providing insights into

Mitigating Green Oil Deactivation in Acetylene Hydrogenation Using Carbon‐Supported Pd Catalysts

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study reveals that carbon‐supported palladium catalysts outperform alumina‐supported ones in resisting deactivation during acetylene hydrogenation. Carbon nanotubes prove exceptionally stable, while graphite deactivates rapidly. Catalyst surface area, not green oil formation, emerges as the key factor in deactivation rates.
