CO2 Methanation Of Co/CeO2 Prepared by Wetness Impregnation of Co on Flame‐Synthesized CeO2
ChemCatChem, Volume 17, Issue 17, September 5, 2025.Tailoring the interaction between cobalt (Co) species and flame‐synthesized cerium oxide (CeO2) influences selectivity in CO and CO2 hydrogenation. The chemical state of Co in catalysts with varying loadings was analyzed. Correlations between chemical state, particle size, and catalytic performance offer insights for designing more selective and stable

Chemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.Heme proteins are important biomolecules. Proximal cysteine thiolate ligation is found both in heme enzymes such as cytochromes P450 (CYP) and regulatory proteins such as CooA, a CO sensor. The role of H‐bonding to this cysteine is explored in CooA, including variants, and CYP119 using optical and paramagnetic resonance spectroscopies, which highlight ...
