  • Publication number: 20200070094
    Abstract: A three-dimensional photo/electrodialysis unit includes four compartments. A first compartment holds a three-dimensional electrode and a group of one or more electrochemically active redox species. A first electroactive cation selective membrane couples the first compartment to a second compartment that provides a first feedstock. An electroactive anion selective membrane couples the second compartment to a third compartment that provides a second feedstock.

  • Publication number: 20190249313
    Abstract: A solar fuel production assembly comprises a separation structure including an ion conducting membrane structurally integrated with one or more solar fuel production units that absorb solar energy to drive one or more redox reactions. A reduction half-reaction occurs on a first side of the separation structure to produce one or more reduction products and an associated oxidation half-reaction occurs on an opposite second side of the separation structure to produce one or more oxidation products. The one or more reduction products are collectable from the first side and the one or more oxidation products are collectable from the second side of the separation structure. The ion conducting membrane provides facile transport of ions to reduce ion transfer ohmic losses associated with the one or more redox reactions, and also provides for separation of the one or more reduction products from the one or more oxidation products.

  • Patent number: 10100415
    Abstract: A multi-junction artificial photosynthetic unit includes an active element with a plurality of semiconducting layers, with metal layers deposited between the semiconductor layers appropriately forming Schottky barrier junctions or ohmic junctions with a surface of an adjacent semiconductor layer. The active element is formed within a protective structure formed of porous aluminum oxide. Successive layers of the active element can be formed within the protective structure, and additional layers and junctions can be added until desired photovoltages are achieved. A photoreactor for the production of fuels and chemicals driven by solar-powered redox reactions includes a bag reactor filled with a feedstock solution. A plurality of multi-junction photosynthetic units are placed in the feedstock solution to drive the redox reactions and produce the desired fuels and chemicals.

  • Patent number: 9935234
    Abstract: A photoelectrosynthetically active heterostructure (PAH) is manufactured by forming or providing cavities in an electrically insulating material; forming or providing an electrically conductive layer on a side of the electrically insulating material; depositing an electrocatalyst cathode layer in the cavities; depositing one or more layers of light-absorbing semiconductor material in the cavities; depositing an electrocatalyst anode layer in the cavities; removing the layer of electrically conductive metal; and forming a hydrogen permeable layer over the electrocatalyst cathode layer. The one or more layers of light-absorbing semiconductor material can form a p-n junction or Schottky junction. The PAH can be used in photoelectrosynthetic processes to produce desired products, such as reduction product (e.g., methane gas, methanol, or carbon monoxide) from carbon dioxide and liquid waste streams.

  • Patent number: 9593053
    Abstract: A two-step process, consisting of a photoelectrosynthetic process combined with a thermochemical process, is configured to produce a reduction product (e.g., methane gas, methanol, or carbon monoxide) from carbon dioxide and liquid waste streams. In a first step, photoelectrosynthetically active heterostructures (PAHs) and sunlight are used to drive oxidation/reduction reactions in which one primary product is hydrogen gas. In the second step, hydrogen generated in the first step is thermally catalytically reacted with carbon dioxide to form a reduction product from carbon dioxide (e.g., CO, formaldehyde, methane, or methanol). Synthesis gas (CO and H2) can be further reacted to form alkanes. The methods and systems may employ PAHs known in the art or improved PAHs having lower costs, improved stability, solar energy conversion efficiency, and/or other desired attributes as disclosed herein.
