Highly Dispersed Pd@ZIF‐8 for Photo‐Assisted Cross‐Couplings and CO<sub>2</sub> to Methanol: Activity and Selectivity Insights
Abstract Our study unveils a pioneering methodology that effectively distributes Pd species within a zeolitic imidazolate framework‐8 (ZIF‐8). We demonstrate that Pd can be encapsulated within ZIF‐8 as atomically dispersed Pd species that function as an excited‐state transition metal catalyst for promoting carbon–carbon (C−C) cross‐couplings at room temperature using visible light as the driving force. Furthermore, the same material can be reduced at 250 °C, forming Pd metal nanoparticles encapsulated in ZIF‐8. This catalyst shows high rates and selectivity for carbon dioxide hydrogenation to methanol under industrially relevant conditions (250 °C, 50 bar): 7.46 mol methanol mol metal −1 h −1 and >99 %. Our results demonstrate the correlations of the catalyst structure with the performances at experimental and theoretical levels.
