      Building better catalysts from the bottom-up The cover picture shows how mesoporous catalysts can now be fabricated using building blocks containing a wide variety of chemical functionalities. In their Review on p. 844 ff., E. Serrano et al. describe the use of silicon alkoxide-terminated nanoparticles and metal complexes as building blocks in the preparation of functional mesoporous materials containing these moieties in their pore walls and their catalytic performance. In their Editorial of this Special Issue, R. Luque and J. Garcia Martinez expand on this idea and the potential of bottom-up strategies in the synthesis of better catalysts (p. 827 ff.).

      Food for thought! The cover picture shows the selective transformation of cinnamyl alcohol into cinnamaldehyde on passage through a mesoporous Pd silica catalyst. In their Full Paper on p. 939 ff., C. M. A. Parlett and A. F. Lee et al. reveal how tuning the architecture of porous silica supports controls the dispersion and oxidation state of entrained palladium nanoparticles, and, consequently, their activity towards aerobic selective alcohol oxidation. Through a combination of HRTEM, X-ray and in situ DRIFT spectroscopies, they identify surface PdO as the catalytically active phase. Silica supports comprising three dimensional, interconnected pore networks offer enhanced activity in palladium catalyzed selective oxidations.

      Faster Bi itself! The cover picture illustrates the formation of active BixOy nanoparticles from bismuth impregnated mesoporous silicas (Bi-TUD-1) in the presence of light and hydrogen peroxide and the fascinating autocatalysis observed from the application of these particles to the decomposition of methylene blue. In their Full Paper on p. 959 ff., A. J. Ward et al. describe the mechanism and kinetics of methylene blue decomposition over these catalysts, with increasing photochemical oxidation activity observed with decreasing bismuth loadings. It was determined that singlet oxygen was responsible for the oxidation and proposed that lower bismuth concentrations favoured the formation of smaller bismuth species in the silica framework.

      Driving the wheel! This cover picture shows the schematic framework of mesoporous silica foam (MCF) that is used for the immobilization of glucose-6-phosphate dehydrogenase (G6PDH) a cofactorregenerating enzyme. In their Full Paper on p  931 ff., M. Fröba et al. focused on the functionalization of the MCF to tailor this support according to the needs of G6PDH. The 3-dimensional connected spherical pores appeared an ideal host for the enzyme in terms of substrate diffusion and enzyme stabilization. These results prove that this biocatalyst can be used to efficiently drive the wheel of cofactor regeneration.

      Bottoms-up! Sol–gel coordination chemistry enables the production of the so-called mesoporous metal complex-silica materials by use of a coordination complex with ligands containing terminal trialkoxysilane groups, which can be hydrolyzed with or without the presence of other silica sources.

      Suits you sir! Ordered inorganic porous materials can be tailored to optimally host and protect proteins. In the early years of enzyme adsorption in ordered porous materials, mesoporous silicas were the prominent supports, but today there exists a variety of porous materials that can be designed efficiently for the uptake of proteins. Periodic mesoporous organosilicas (PMOs), metal-organic frameworks (MOFs) or magnetic porous materials are only some of them.
