  • Publication number: 20210163685
    Abstract: An improved photosensitizer for a photocathode comprises an oligomeric or polymeric chromphore absorbing, as an ensemble, light at (a) wavelengths at or greater than 420 nm that includes at least 3 identical or different suitable monomeric chromophore units carrying at least two substituents each comprising at least one alkylene, alkenylene and/or alkynylene chain having a chain length of at least 3 carbon atoms, those substituents being terminated by thiol groups, wherein the oligomeric or polymeric chromphore has a disulfide bond between each of the chromophores. A photocathode comprising the photosensitzer is useful for the reduction of water-soluble chemicals in oxidized forms, including protons, with the aid of visible light in a system comprising the photocathode and a photoanode or any other anode or source of electrons. A method for reducing chemicals soluble in aqueous media in oxidized forms, including protons, in aqueous solutions by means of the photocathode is also disclosed.

  • Patent number: 8883671
    Abstract: A monolithic catalyst system for the cleavage of water into hydrogen and oxygen comprises a first photoactive material capable by itself or together with an auxiliary material and/or an auxiliary catalyst when irradiated with light having a wavelength?420 nm of generating oxygen and protons from water, and a second photoactive material capable by itself or together with an auxiliary material and/or an auxiliary catalyst when irradiated with light having a wavelength?420 nm of reducing protons in water to hydrogen. The first and second photoactive materials are in electrical contact via an electron-conducting material.

  • Publication number: 20130164265
    Abstract: This invention provides compositions and methods of manufacturing such compositions that employ GRAS compounds which can act to promote the generation of stem, epidermal or other skin cells in the epidermis, activation of collagen synthesis, activation of hyaluronic acid synthesis, enhanced skin hydration, and dermal healing by stimulating stem cell and fibroblast migration to sites of needed repair. These compositions and methods are useful for rejuvenating the skin and for treating some skin-related aging or other dermal damaging conditions, including wrinkle reduction and treatment of minor dermal wounds.

  • Publication number: 20130037414
    Abstract: A monolithic catalyst system for the cleavage of water into hydrogen and oxygen with the aid of light comprises a first photoactive material capable by itself or together with one or more of an auxiliary material and an auxiliary catalyst of generating oxygen and protons from water, when irradiated with light having a wavelength ?420 nm of generating oxygen and protons from water, and a second photoactive material selected from gallium arsenide, copper indium disulphide/selenide, copper indium gallium disulphide/selenide and cadmium sulphide/selenide/telluride and having a water resistant coating transparent to visible light capable of the reducing protons in water to hydrogen, when irradiated with visible light. The first photoactive material and the second photoactive material are supported on at least one substrate and are in electrical contact, particularly in direct electrical contact, exclusively via one or more electron-conducting materials.

  • Publication number: 20120247946
    Abstract: Described is a monolithic catalyst system (1) for the cleavage of water into hydrogen and oxygen with the aid of light, comprising a first photoactive material (50) capable by itself or together with one or more auxiliary catalysts when irradiated with light having a wavelength ?420 nm of generating oxygen and protons from water, and a second photoactive material (60) capable by itself or together one or more auxiliary catalysts (92) when irradiated with light having a wavelength ?420 nm of reducing protons in water to hydrogen, the first photoactive material (50) and second photoactive material (60) being in electrical contact via one or more electron-conducting materials (30, 20, 40, 60a) the system being in that characterized in that a load or an electric consumer is interposed in between at least one electron-conducting material. Likewise described is a method of generating oxygen, hydrogen and electricity from water using the catalyst system.
