Optimization of Active Manganese Oxide Electrodeposits Using Graphenated Carbon Nanotube Electrodes for Supercapacitors ... (14) In contrast, thin graphitic and graphene nanosheets have proven to be an ideal substrate for electrodeposition of thin, uniform, and conformal MnO2 coatings(9) given the greater reactivity and electrochemical activity of graphene edge-planes. ... The electrode performance could be tuned by optimizing the density of graphene foliates on the g-CNTs, which served as electrochemically active nucleation sites and enabled control of the morphological properties (e.g., density, size, location, thickness, and nanostructure) of MnO2 electrodeposits. ...
