Electrodeposition of Inorganic Oxide/Nanocarbon Composites: Opportunities and Challenges

Carbon nanomaterials, especially carbon nanotubes and graphene (either alone, or as building blocks of organized 3D superstructures), are attracting significant attention as large‐surface‐area electrode support materials. Their composites with inorganic oxides represent an interesting class of new functional materials. This Minireview critically focuses on the use of electrosynthetic (and photoelectrosynthetic) methods for preparing oxide nanoparticles on nanocarbon‐modified electrode surfaces. We focus on how electrodeposition can be used to tune composition, crystal structure, and morphology of the nanocomposites for targeted applications. Finally, selected examples will be given for how these electrosynthesized hybrid assemblies can be deployed in various application avenues.
