摘要： A method for preparing a COF-protected electrode and an electrode are provided. The method includes mixing an organic framework, a small molecular organic acid and a solvent, adding a polar aqueous solution containing a substrate thereto, mixing the above uniformly and heating the system at a low temperature under an inert atmosphere, filtering the solution to obtain precipitates, washing and drying the precipitates to obtain a COF film grown on a surface of the substrate; coating a protective layer on the COF film to obtain a substrate/COF/protective layer film; etching off the substrate to obtain a COF/protective layer film; and transferring the COF/protective layer film to a surface of the electrode, and removing the protective layer.

摘要： An electrolyzer system has a first half cell with a first electrode and a separator disposed adjacent a side of the first half cell. The separator is configured to separate the first half cell from an adjacent second half cell, and the first electrode is in contact with a face of the separator. The first electrode has a mesh, and portions of the mesh that are in contact with the separator are flattened.

摘要： Catalyst ink formulas for the preparation of CCMs are described. The catalyst ink formulas comprise a catalyst, an ionomer, a solvent, and a porogen soluble in the solvent. The catalyst ink formula may also comprise an additive, such as an electron conductive polymer. The anode catalyst coating layer or both the anode and the cathode catalyst coating layers prepared from the catalyst ink formula comprises uniformly distributed nanopores that allow easy gas removal and uniform water feed distribution, which will avoid or reduce the direct energy losses for the electrolyzers. Catalyst coated membranes and methods of making a catalyst coated membranes are also described.

摘要： The present invention relates to a one-step process for preparation of “in-situ” or “ex-situ” self-organized and electrically conducting polymer nanocomposites using thermally initiated polymerization of a halogenated 3,4-ethylenedioxythiophene monomer or its derivatives. This approach does not require additional polymerization initiators or catalysts, produce gaseous products that are naturally removed without affecting the polymer matrix, and do not leave by-product contaminants. It is demonstrated that self-polymerization of halogenated 3,4-ethylenedioxythiophene monomer is not affected by the presence of a solid-state phase in the form of nanoparticles and results in formation of 3,4-polyethylenedioxythiophene (PEDOT) nanocomposites.

摘要： A cathode catalyst layer includes a cathode catalyst to hydrogenate a substance to be hydrogenated, a porous catalyst support supporting the cathode catalyst, and a non-porous body including an aggregate of arbitrary primary particles. A volume fraction of the non-porous body in the cathode catalyst layer is higher than 10 vol % with respect to the volume of the total solid content of the cathode catalyst layer.

摘要： An electrode for a reaction in a chemical cell includes a substrate having a surface, an array of nanostructures supported by the substrate and extending outward from the surface of the substrate, each nanostructure of the array of nanostructures having a semiconductor composition, and a catalyst arrangement disposed along each nanostructure of the array of nanostructures, the catalyst arrangement comprising a metal-based catalyst for the reaction in the chemical cell. The semiconductor composition of each nanostructure of the array of nanostructures establishes sites at which the metal-based catalyst is anchored to the nanostructure. The array of nanostructures and the catalyst arrangement are configured such that the metal-based catalyst is distributed along sidewalls of each nanostructure of the array of nanostructures at an atomic scale.

摘要： A zinc-based metal organic framework and method of making is described. The zinc-based metal organic framework is in the form of an interpenetrating diamondoid framework where each Zn2+ ion center is linked with four other Zn2+ ion centers in a distorted tetrahedral geometry. The linking occurs through diamine and dicarboxylic acid linkers. The zinc-based metal organic framework may be deposited on a transparent conducting film and used as a photoelectrode for photoelectrochemical water splitting.
