Bifunctional Europium for Operando Catalyst Thermometry in an Exothermic Chemical Reaction.
Angew Chem Int Ed Engl

Article Synopsis
- The temperature reported in heterogeneous catalysis often doesn't accurately reflect the actual temperature of the catalyst itself, which can impact catalytic performance.
- EuOCl is used as a solid catalyst and thermometer to measure the catalyst temperature in real-time during the methane oxychlorination reaction, revealing a temperature difference of up to +16 °C between the catalyst and the oven.
- Understanding the temperature dynamics using operando thermometry could enhance our knowledge of catalysts and contribute to safer operations in chemical processes.
Polyolefin catalysts are characterized by their hierarchically complex nature, which complicates studies on the interplay between the catalyst and formed polymer phases. Here, the missing link in the morphology gap between planar model systems and industrially relevant spherical catalyst particles is introduced through the use of a spherical cap Ziegler-type catalyst model system for the polymerization of ethylene. More specifically, a moisture-stable LaOCl framework with enhanced imaging contrast has been designed to support the TiCl pre-active site, which could mimic the behaviour of the highly hygroscopic and industrially used MgCl framework.
