Our research collaboration with DECHEMA reached the Front Cover of ChemElectroChen journal. The ground-breaking approach illustrates a chimney made of Sn-modified geopolymer-bricks. Functionalized geopolymers can be applied as hybrid material for construction and as an electrode for CO2 electrolysis to formate. The cover was designed by one of the authors Jürgen Schuster and the designer Verena Stöckl. More information can be found in the . Research Article by J.Schuster et al.
