The cover picture shows a SEM image of a semiconducting CuTCNQ microrod whose surface is decorated with metal nanoparticles by a simple galvanic replacement process. A. O'Mullane and A. Pearson report on the use of this composite material as a catalyst for reducing Cr VI ions to a less hazardous Cr III state using thiosulfate ions at ambient temperature in their Full Paper on page 1343 . The nature of the semiconducting substrate and metal nanoparticle combination is hypothesized to be highly influential on the reaction rate with the CuTCNQ/Pt composite demonstrating the best results.
