PPS issue 4 is now published online – Solar Chemistry & Photocatalysis: Environmental Applications

The latest issue of PPS is now available to read online!  This month’s issue is a themed issue of contributions from the 7th European Meeting on Solar Chemistry & Photocatalysis: Environmental Applications (SPEA 7), held in Porto from 17th to 20th June 2012.  Read the Editorial by Guest Editors Joaquim Faria and Sixto Malato here.

PPS issue 4, 2013, front coverThe front cover highlights work by Roland Marschall and co-workers from Ruhr-University Bochum, Germany.  They developed barium tantalate composites which showed enhanced photocatalytic hydrogen generation.  After preparing (111)-layered Ba5Ta4O15photocatalysts via a solid-state reaction route and a citrate synthesis route, X-ray powder diffraction and absorption spectroscopy determined the presence of a second phase – Ba3Ta5O15.  The Ba5Ta4O15/Ba3Ta5O15 composites demonstrated up to 160% higher hydrogen evolution rates than for pure Ba5Ta4O15.  In addition, only very small amounts of Rh co-catalyst (0.025%) were needed to achieve these results.
