A novel versatile light-triggered strategy is developed to organize inorganic nanoparticles into nanovesicles based on the photo-oxidation of simple and commercial thiols as described on page 5613(DOI:10.1002/adma.201401182) by T. Zhang, Z. Tang, Z. Nie, and co-workers. Thanks to the vesicular structures, an improved catalytic activity and unprecedented catalytic stability towards solar-driven hydrogen production is found compared to individual nanoparticles, indicating that this approach would lead to new functional nano-architectures with various applications.

Ultrafine metal nanoparticles can be supported on graphene nanosheets and encapsulated by a thin mesoporous silica layer to produce a robust catalyst, as demonstrated by Y. Yin, T. R. Zhang, et al. in their Communication (DOI: 10.1002/anie.201306863). The catalyst exhibits high activity, good stability against sintering under high temperature conditions, and excellent recycling and reusability in both gas- and solution-phase reactions.
