摘要： Photocatalysts for reduction of carbon dioxide and water are provided that can be tuned to produce certain reaction products, including hydrogen, alcohol, aldehyde, and/or hydrocarbon products. These photocatalysts can form artificial photosystems and can be incorporated into devices that reduce carbon dioxide and water for production of various fuels. Doped wide-bandgap semiconductor nanotubes are provided along with synthesis methods. A variety of optical, electronic and magnetic dopants (substitutional and interstitial, energetically shallow and deep) are incorporated into hollow nanotubes, ranging from a few dopants to heavily-doped semiconductors. The resulting wide-bandgap nanotubes, with desired electronic (p- or n-doped), optical (ultraviolet bandgap to infrared absorption in co-doped nanotubes), and magnetic (from paramagnetic to ferromagnetic) properties, can be used in photovoltaics, display technologies, photocatalysis, and spintronic applications.

摘要： The invention relates to a nano-biohybrid organism (or nanorg) comprising one of at least seven different core-shell quantum dots (QDs) or gold nanoparticle clusters, with excitations ranging from ultraviolet to near-infrared energies, couple with targeted enzyme sites in bacteria. When illuminated by light, these QDs drive the renewable production of biofuel molecules and chemicals using carbon-dioxide (CO2), water, and nitrogen (from air) as substrates. Nanorgs catalyze light-induced air-water-CO2 reduction with a high turnover number (TON) of approximately 106-108 (mols of product per mol of cells) to biofuels such as isopropanol (IPA), butane diol, gasoline additives, gasoline substitutes, 2,3-butanediol (BDO), C11-C15 methyl ketones (MKs), and hydrogen (H2); Sand chemicals such as formic acid (FA), ammonia (NH3), ethylene (C2H4), and degradable bioplastics, e.g. polyhydroxybutyrate (PHB). These nanorg cells function as nano-microbial factories powered by light.
