Description
Scanning electron microscopy image of nanobelts of a material containing gallium nitride and zinc oxide, which might be used as a catalyst to efficiently split water to produce hydrogen for fuel cells. Their flat shape, like plant leaves, is expected to facilitate this photocatalytic reaction. In chemistry, photocatalysis is the acceleration of a photoreaction in the presence of a catalyst. In catalyzed photolysis, light is absorbed by an adsorbed substrate. In photogenerated catalysis, the photocatalytic activity (PCA) depends on the ability of the catalyst to create electron-hole pairs, which generate free radicals able to undergo secondary reactions. Nanotechnology (nanotech) is the manipulation of matter on an atomic, molecular, and supramolecular scale.
