  • Publication number: 20180229227
    Abstract: Disclosed is a catalytic system for the reduction of carbon dioxide to carbon monoxide. The catalytic system includes an iridium (Ir) photosensitizer and a TiO2/Re(I) complex catalyst. No additional process is required to anchor the molecule-based dye compound on TiO2 in the synthesis of the catalytic system. This enables the synthesis of the catalytic system in a relatively easy manner for groups of photosensitizer candidates. In addition, the catalytic system can be utilized as a platform for more easily evaluating the abilities of photosensitizers. Furthermore, the catalytic system can find application in various fields due to its ability to selectively produce carbon monoxide gas with high efficiency.

  • Patent number: 9236194
    Abstract: Dye-sensitized semiconducting metal oxide films for photoanodes, photoanodes incorporating the films and DSCs incorporating the photoanodes are provided. Also provided are methods for making the dye sensitized semiconducting metal oxide films. The methods of making the films are based on the deposition of an encapsulating layer of a semiconducting metal oxide around the molecular anchoring groups of photosensitizing dye molecules adsorbed to a porous film of the semiconducting metal oxide. The encapsulating layer of semiconducting metal oxide is formed in such a way that it is not coated over the chromophores of the adsorbed dye molecules and, therefore, allows the dye molecules to remain electrochemically addressable.
