Inside Back Cover: State-of-the-Art Aluminum Porphyrin-based Heterogeneous Catalysts for the Chemical Fixation of CO2 into Cyclic Carbonates at Ambient Conditions (ChemCatChem 5/2017).

The Cover shows a state‐of‐the‐art aluminum porphyrin‐based hyper‐crosslinked polymer for the chemical fixation of CO2 into cyclic carbonates under mild conditions.In their Full Paper, Y. J. Chen et al. demonstrate the outstanding catalytic activity and excellent reusability of aluminum porphyrin‐based heterogeneous catalysts in the solvent‐free synthesis of cyclic carbonates from epoxides and CO2 in the presence of tetrabutylammonium bromide as cocatalyst.
