Cover Story (view full-size image): The cover illustrates a metal–semiconductor/polyaniline nanocomposite with spectacular catalytic properties. The nanocomposites catalyze the decomposition of methyl orange (MO) in darkness. Indeed, the RuO2–TiO2 mixed oxide is an excellent photocatalyst under visible light, while the nanocomposite RuO2–TiO2/aryl/polyaniline exhibits unique, fast catalytic performance in the dark. Total discoloration of MO was noted without any spectral evidence for organic products, thus suggesting complete mineralization of the dye. This activity does not only depend on the components that constitute these materials but also on the subtle interface chemical composition which is driven by diazonium modification of RuO2–TiO2.
