Abstract

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.
