In-situ self-assembly of graphene supported MnO2 nanowires for enhanced water oxidation in both alkaline and neutral solutions
MetadataShow full item record
The sluggish water oxidation reaction represents a significant challenge in water splitting for energy storage using hydrogen. We herein reported a graphene supported MnO2 nanowires with an ultrasmall diameter and ultrahigh aspect ratio using a novel in-situ self-assembly approach. This nanostructure was investigated as water oxidation catalysts, showing an ultrahigh catalytic activity and good durability in both alkaline and neutral conditions. © The Electrochemical Society.
