文摘

The incorporation of single cobalt active sites within a graphene matrix leads to a composite material with superior activity and stability when used as a counter electrode for the interconversion of the redox couple I⁻/I₃⁻. In their Communication on page 6708 ff., D. Deng, W.-H. Zhang, and co-workers further show that the use of this material as a counter electrode in a dye-sensitized solar cell (DSSC) leads to a better power conversion efficiency than the use of a platinum counter electrode.
