Activation of carbon-supported catalysts by ozonized acidic solutions for the direct implementation in (electro-)chemical reactorsElectronic supplementary information (ESI) available. See DOI: 10.1039/c4cc08480b

This work introduces a practical and scalable post-synthesis treatment for carbon-supported catalysts designed to achieve complete activation and, if necessary, simultaneously surface dealloying. The core concept behind the method is to control the potential without utilizing any electrochemical equipment, but rather by applying an appropriate gas mixture to a catalyst suspension. Development of a novel and scalable ex situ technique for the simultaneous activation/dealloying of Pt-based nanocatalysts for energy conversion applications.
