The present application relates to an electrode holder and a floating device that comprises same for purifying bodies of water. The electrode holder comprises a base, a metal fastener and a cover. A plurality of electrodes are embedded in the metal fastener, housed inside the base and under the cover. The electrodes can be made of copper, zinc, silver, gold, stainless steel or combinations thereof. The metal fastener can be connected to any electric power source. The flow of electric energy towards the electrodes that are in contact with the water generates an oxidation-reduction reaction, releasing ions, which have a purifying effect, into the water. The device which comprises this electrode holder also comprises a photovoltaic module, an energy storage module that serves as an electric power source for the electrodes, a pH meter and an external structure.

Functionalized substrates are provided comprising a substrate and a plurality of transition metal dichalcogenide (TMD) heterostructures on a surface of the substrate, each TMD heterostructure comprising a TMD shell over a heterogeneous nucleation site, thereby providing a core-shell heterostructure, the heterogeneous nucleation site composed of a heterogeneous nucleation material; and a TMD wing extending outwardly from the core-shell heterostructure and non-parallel to and above the substrate surface. Electrocatalytic systems comprising the functionalized substrates are also provided.

Provided in this disclosure is an electrolysis system using voltage in a purely physical process, without resorting to passing current through an electrolyte in a chemical process. The present invention includes a tri-coil design resonant cavity transformer that utilizes the dielectric properties of a material acting as part of a “closed loop” electrical (Resistor, Inductor, Capacitor) RLC circuit. The tri-coil transformer (or TCT) is tuned to the dielectric properties of a suitable material, which can be water, liquid metals, or even ambient air. The TCT can be a tri-coil resonating cavity transformer employing either a Maxwell or Helmholtz tri-coil design. The present invention entails a physical approach to electrolysis based on voltage and not amperage to dissociate a selected dielectric medium, an approach that is 180 degrees out of phase from traditional Faraday electrolysis.

An individual solid oxide cell (SOC) constructed of a sandwich configuration including in the following order: an in oxygen electrode, a solid oxide electrolyte, a fuel electrode, a fuel manifold, and at least one layer of mesh. In one embodiment, the mesh supports a reforming catalyst resulting in a solid oxide fuel cell (SOFC) having a reformer embedded therein. The reformer-modified SOFC functions internally to steam reform or partially oxidize a gaseous hydrocarbon, e.g. methane, to a gaseous reformate of hydrogen and carbon monoxide, which is converted in the SOC to water, carbon dioxide, or a mixture thereof, and an electrical current. In another embodiment, an electrical insulator is disposed between the fuel manifold and the mesh resulting in a solid oxide electrolysis cell (SOEC), which functions to electrolyze water and/or carbon dioxide.
