Nanomaterials play a key role in both academic and industrial research. Nanocatalysis is one of nanotechnology's oldest applications. Catalysis is an important aspect of energy production, chemical manufacturing, and environmental remediation. Catalysis is used in more than half of all chemical products and practically all of the world's chemical processes. These proportions will continue to rise in order to meet our ever-increasing aspirations for sustainable processes with better atom-economic and environmental benefits. Nanocatalysis is a rapidly expanding discipline in which nanomaterials are used as catalysts in a variety of homogeneous and heterogeneous catalysis processes.
