Electronic and Structural Determinants of Activity and Stability in Noble Metal OER Catalysis

ChemCatChem, Volume 18, Issue 7, 14 April 2026.
Activity and stability in noble metal oxygen evolution reaction (OER) catalysts arise from coupled electronic and structural effects at the catalyst surface. Electronic engineering, crystallographic control, lattice modulation, and surface engineering tune the d‐band structure, oxidation state, strain, and coordination environment of noble metal based ...

Stability and Performance of Sn–Zn/C versus Sn–Cu/C Bimetallic Catalysts for Electrochemical Formic Acid Production Under Realistic Diluted Feed Conditions

ChemElectroChem, Volume 13, Issue 7, 1 April 2026.
Beyond Pure CO2: Sn–Zn/C and Sn–Cu/C show comparable formic acid production under pure CO2 (40.81% vs. 29.17% FE), but only Sn–Zn/C maintains activity under realistic 50% CO2 dilution (42.7% retention) while Sn–Cu/C fails completely. Multimodal characterization reveals that thermodynamic oxide phase compatibility and textural stability are critical ...

Interference of TiO2 in Fricke Dosimetry: Adsorption Mechanisms and Dose Measurement Challenges under Gamma Irradiation

ChemistryOpen, Volume 15, Issue 4, April 2026.
The presence of TiO2 in Fricke dosimetric systems introduces complex interferences under gamma irradiation. Adsorption of Fe2+/Fe3+ ions, coupled with radiolytic and surface‐mediated processes, alters redox equilibria and apparent absorbed dose values, highlighting critical challenges in chemical dosimetry applied to heterogeneous radiolytic ...

High Efficiencies in Gd2Ru2O7 Pyrochlore Oxide Photoanode‐Based Dye‐Sensitized Solar Cells Using Natural Dyes From Anacardium, Baphia nitida, and Lannea kerstingii Barks

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 4, Page 453-464, April 2026.
High performance of Gd2Ru2O7‐based natural dye‐sensitized solar cell using three different dyes (Anacardium, B. nitida, and Lannea kerstingii barks) has been developed. Enhanced energy conversion efficiency values were obtained compared to classical TiO2 P25‐based DSSC. ABSTRACT Natural dye‐sensitized solar cells (DSSC‐N), inspired by the principles of
