Title: ZnO structures and methods of use
Usefulness: ZnO structures and methods of use
Summary: The zinc oxide structure is useful: for decomposing methanol; for hydrogenation of carbon dioxide (all claimed); as catalyst for methanol formation at low temperature, dimethyl carbonate formation and photocatalysis; in solar cells, fuel cells, electrochemical cells, direct methanol fuel cells, electric vehicle propulsion and in alternative energy technologies including hydrogen generation or storage; and in high density magnetic data storage and as a component or interconnect in nanodevices.
Novelty: Zinc oxide structure, useful e.g. for decomposing methanol, for hydrogenation of carbon dioxide, in solar cells, fuel cells, electrochemical cells and in direct methanol fuel cells, comprises microrods or nanorods

*Abstract

This invention takes advantage of the unique surface chemistry of a ZnO crystalline nanostructure to catalyze a variety of chemical reactions. One such reaction is the hydrogenation of carbon dioxide to methanol. Alcohols interacts both molecularly and dissociatively with the single-crystalline ZnO surfaces at room temperature and can be partially oxidized by increasing the temperature.
