摘要：

A hybrid electrocatalyst for the oxygen reduction reaction (ORR), consisting of Co1-xS nanoparticles directly nucleated and grown on sheets of reduced graphene oxide (RGO; see SEM image), was prepared by a mild solution-phase reaction followed by an annealing step. The Co1-xS-RGO hybrid has the highest catalytic performance of all cobalt chalcogenide based ORR catalysts, as revealed inter alia by measurements with a rotating-disk electrode (see picture; RHE = reversible hydrogen electrode). © 2011 Wiley-VCH Verlag GmbH & Co.
