Abstract

original image

Enhanced effective photocatalyst! The cover picture shows the photodegradation of methylene blue by a heterogeneous mixture of highly uniform hollow spheres, assembled from truncated rhomboid anatase TiO2 nanoparticles and conventional micro-sized TiO2. In their Full Paper on p. 1871 ff., C.-Y. Lee et al. reveal the factors that enhanced the photocatalytic performance. The scattering structure enhanced the light harvesting, the heterojunction increased the photo-efficiency, and the active surface, {1 0 1} and {0 0 1}, improved the reaction activity. The rate constant for methylene blue degradation by this catalyst was approximately twice that of commercial P25.
