Copolymerization of the cationic water-oxidation catalyst [Ru2II(mu-bpp)(t-trpy)2(H2O)2]3+ (1) with a cobalt cobaltabisdicarbollide monomer (2) generates a new material, FTO/poly-(1-co-2), that is capable of oxidizing water to molecular dioxygen with a turnover number (TN) of 250 (see picture). This represents the best performance ever obtained in a heterogeneous phase using a chemical oxidant.
