dc.description.abstract | In this work, we evaluated the oxygen evolution performance of cobalt oxide (CoOx)-coated carbon fiber paper in electrochemical water splitting. For a uniform coating of CoOx layers along the carbon fiber paper, the atomic layer deposition (ALD) technique was applied. We achieved a uniform and conformal coating of atomic-layer deposited CoOx (ALD-CoOx) on the carbon fiber paper. The overpotential for oxygen evolution measured for the optimized ALD-coated carbon fiber paper was as low as 343 mV at 10 mA cm(-2), which is competitive with the activity of state-of-the-art CoOx prepared on electrodes with large surface areas. Oxygen evolution is not enhanced after a critical thickness, about 28 nm in our study, is reached. The optimal thickness of the ALD-CoOx film is dependent on two competing effects: the high oxidation state of cobalt ions in thicker CoOx helps the oxygen evolution, whereas the introduction of a thick oxide coating decelerates the rate of charge transfer at the surface. | - |
