Metal oxides such as TiO2 and SnO2 are important candidates for many applications including fuel cells, lithium-ion batteries, solar cells, water splitting and gas sensing. By combining these materials with graphene, researchers from the Nanomaterials and Energy group at the University of Western Ontario, Canada, hope to create structures with exceptional properties. A recent success is the controlled synthesis of graphene-based TiO2 nanocompsites with tunable structures by atomic layer deposition (ALD).
