    Abstract: A three-dimensional non-noble-metal-based electrocatalysis electrode structure is provided. The electrode structure includes one or more layers of fused and approximately aligned elongated electrocatalyst nanoparticles that include a non-noble metal alloy or non-noble metal compound. Anisotropic nanochannels are positioned between the fused and approximately aligned elongated electrocatalyst nanoparticles that are configured to transfer generated gas bubbles therethrough. The elongated electrocatalyst nanoparticles may be nanorods that may have a diameter of approximately 20 to 50 nanometers and a length of approximately 80 to 300 nanometers. The anisotropic nanochannels may have a channel width of approximately 50-150 nanometers. The non-noble metal may be one or more of iron, cobalt, nickel, copper, molybdenum, or tungsten. The one or more layers of fused and approximately aligned elongated electrocatalyst nanoparticles may be 3-D printed elongated electrocatalyst nanoparticles, and each layer has a thickness of approximately 50 to 200 microns.

    Abstract: An electrode of a chemical cell includes a substrate having a surface, an array of conductive projections supported by the substrate and extending outward from the surface of the substrate, each conductive projection of the array of conductive projections having a semiconductor composition for catalytic conversion of carbon dioxide (CO2) in the chemical cell, and a plurality of nanoparticles disposed over the array of nanowires, each nanoparticle of the plurality of nanoparticles having a metallic composition for the catalytic conversion of CO2 in the chemical cell. Each nanoparticle of the plurality of nanoparticles has a size at least an order of magnitude smaller than a lateral dimension of each conductive projection of the array of conductive projections.

    Abstract: Improvements in an electrolysis electrode structure where fluid or gas enters a chamber with cathode and anode charged conductors to polarize and separate the flow into two separate paths for electrolysis of the fluid or gas. The conductors wrap around magnets to extend the range of the polarizing field beyond the range of the electrode conductors. Iron particles fan-out from the conductors and magnets to further extend the polarizing field from the magnets as well as creating increased surface area for gas or liquids to flow within and around the conductors, magnet and iron particles. Noble metal provides a thin plating that locks the position of the particles and provides an open structure to allow for the flow of gas or fluids at a high rate of flow and prevents the iron particles from being eroded by the flow.

    Abstract: The present invention discloses a bismuth-copper single-atom alloy catalyst, a preparation method and an application thereof. The catalyst includes copper nanoparticles and bismuth atoms. The copper nanoparticles are of a polycrystalline structure, and the bismuth atoms are dispersed in the copper nanoparticles in a single-atom form. The catalyst is prepared by means of thermal decomposing the metal complex and the followed in-situ electroreduction. The preparation method of the bismuth-copper single-atom alloy catalyst of the present invention is simple to operate, and the single-atom bismuth content is adjustable. The single-atom bismuth content can be adjusted by changing reaction conditions. By means of loading mutually isolated bismuth atoms on the copper nanoparticles, the electronic state of copper atoms is adjusted, such that an ability of bismuth-copper single-atom alloy to catalyze carbon-carbon coupling is improved, so as to obtain a higher selectivity of electrocatalytically reducing carbon dioxide to a multi-carbon product, providing a new way for efficient conversion of carbon dioxide.
