Cover Feature: Precursor Nuclearity and Ligand Effects in Atomically‐Dispersed Heterogeneous Iron Catalysts for Alkyne Semi‐Hydrogenation (ChemCatChem 14/2021)

The Cover Feature depicts different single‐atom species stabilized from iron pentacarbonyl on graphitic carbon nitride and their distinct selective hydrogenation activity (shown by the color of the light stream). In their Full Paper, D. Faust Akl et al. investigate the effect of precursor nuclearity on iron alkyne semi‐hydrogenation catalysts. A complex interplay is identified between residual carbonyl ligands (gray and red balls), the interaction with the host, and the metal nuclearity governs the resulting performance. More information can be found in the Full Paper by D. Faust Akl et al.
