Electrolysis Device Having Two Boron Doped Diamond Layers

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention is an electrolysis device featuring a substrate onto which both an anode and cathode are formed from boron-doped diamond layers. The use of boron-doped diamond enables high electrical conductivity and robust chemical resistance. The architecture allows the device to be compact, potentially chip-sized, while being suitable for efficient electrolysis processes, including the production of strong oxidants like ozone and hydroxyl radicals, and the removal or precipitation of metals from solutions.

• Generation of ozone and hydroxyl radicals for water purification, disinfection, or industrial oxidation processes
• Electrolytic precipitation or removal of metals, including heavy metals and valuable metals, from water and industrial effluents
• Descaling and removal of calcium deposits in water systems
• Miniaturized electrolysis chips for embedded water treatment in appliances such as washing machines or dishwashers
• On-site generation of oxidants for environmental cleanup or sanitization
• Production of hydrogen and oxygen gases from water splitting processes
• Industrial or laboratory use in the synthesis of oxidized chemicals or for electrochemical testing

BenefitsContent extracted from patent full text and abstract with AI.

• High durability and chemical resistance due to boron-doped diamond electrodes
• Capability to fabricate miniaturized (chip-scale) electrolytic devices, enabling integration into various systems and appliances
• Efficient and selective production of strong oxidants (ozone, OH radicals) without undesirable by-products like toxic nitrogen oxides
• Supports low working voltages, reducing energy consumption and increasing safety
• Flexible construction allows adaptation for various electrolytes (aqueous or non-aqueous) and target products
• Improved longevity of electrodes compared to conventional materials, leading to lower maintenance and replacement costs
• Potential for higher purity of generated gases or oxidants due to the inert nature of diamond electrodes
