Ir-MnOx catalysts for cyclooctene epoxidation. (A) Faradaic efficiency for cyclooctene epoxidation vs potentials. (B) Comparison of average epoxidation current between Irsingle-MnOx, Ircluster-MnOx, and MnOx. (C) Cyclooctene concentration (at 5 M H2O) and (D) water concentration (at 100 mM cyclooctene) dependences of average epoxide partial current at 1.4 V vs Fc/Fc+. Acetonitrile (ACN) was used as the solvent.
