- Novel electrodes are needed for direct ethanol fuel cells with improved quality. Hierarchical engineering can produce catalysts composed of mesocrystals with many exposed active planes and multi-diffused voids. The paper reports a one-pot, hydrothermal method for fabricating Co3O4/carbon/substrate electrodes, with novel morphological architectures, that provide control over the catalyst mesocrystal morphology. Atomic-scale surface architectures that were continuously ribbed and had grooves oriented along the longitudinal axis were found to improve the efficiency of ethanol electrooxidation. A new approach for the fabrication of multifunctional electrodes was demonstrated to be feasible for application in fuel cells, lithium-ion batteries, and solar cells.
