Breathe manganeasy The cover picture features a low-temperature heterogeneous catalysis as an efficient and economically viable technology for formaldehyde removal from indoor air. In their Full Paper on p. 152 ff., J.-F. Lamonier et al. describe noble metal-free materials—mesoporous silica-confined MnO2 nanoparticles—that are highly active and require only limited energy consumption. MnO2 crystallized in confined space under optimized preparation conditions produces the active material to achieve the complete conversion of formaldehyde at temperatures as low as 130 °C.
