Graphitic nanomaterials with unique and interesting optical, electrical and mechanical properties are excellent candidates for a wide range of applications including energy storage, nano-electronics and medicine.[1],[2],[3] However, synthesis of structures with specific morphologies and properties is essential for successful development of new multifunctional devices. This presentation will highlight the role of growth conditions on the morphological properties of carbon nanomaterials and their diverse applications. Synthesis conditions, such as catalyst composition, heating method, temperature, and hydrocarbon source were found to strongly affect the morphologies of carbon nanotubes and graphene. Various type of catalyst systems were extensively researched for synthesis of one- and two-dimensional carbon nanomaterials. The critical role of the size-dependent catalytic activity of nanoparticles on nanotube synthesis temperature will also be presented. In the second part of this presentation, I will discuss our collaborative efforts on the development of graphene-based systems for multidisciplinary applications including opto-electronic devices, high-performance battery anodes, selective membranes for ion transport studies and sensors (e.g. for circulating tumor cells detection in blood). Development of three-dimensional nanostructures for catalysis and super-capacitor applications will also be discussed.
