Immobilization of a molecular catalyst on carbon nanotubes for highly efficient electro-catalytic water oxidation†
Abstract
Electrochemically driven water oxidation has been performed using a molecular water oxidation catalyst immobilized on hybrid carbon nanotubes and nano-material electrodes. A high turnover frequency (TOF) of 7.6 s−1 together with a high catalytic current density of 2.2 mA cm−2 was successfully obtained at an overpotential of 480 mV after 1 h of bulk electrolysis.
