In this study, a simple technique combining conventional electrospinning and facile gas–solid reaction for fabricating PAN/Ag2S nanofibers was presented and tested. The obtained fibers would have excellent properties such as the flexibility of PAN nanofibers and efficient photocatalysis of the Ag2S nanoshells under visible light. The photocatalytic elimination of RhB in water was used to evaluate the activity and application of the synthesized material under visible light irradiation.

In ebook "Catalysis with supported size-selected Pt clusters: Fundamental UHV and applied ambient experiments" Florian Schweinberger investigates the influence of the precise size of catalytically active species on reactivity. In order to do this he carries out studies both in UHV and under ambient conditions for supported, size-selected Platium clusters (8-68 atoms). Schweinberger probed the electronic structure, adsorption properties and reactivity of two olefins on surfaces and Pt clusters in the submonolayer range.
