発明の名称 (英語) METHOD FOR GENERATING MECHANICAL AND ELECTROCHEMICAL CAVITATION, METHOD FOR CHANGING GEOMETRIC SHAPE AND ELECTROCHEMICAL PROPERTIES OF SUBSTANCE SURFACE, METHOD FOR PEELING OFF RARE METAL, MECHANICAL AND ELECTROCHEMICAL CAVITATION GENERATOR, AND METHOD FOR GENERATING NUCLEAR FUSION REACTION OF DEUTERIUM
発明の概要(英語) Provided are: a method for generating mechanical and electrochemical cavitation; a method for changing the geometric shape and electrochemical properties of the surface of a substance; a method for peeling off a rare metal using the mechanical and electrochemical cavitation thus generated; and a method for causing a mechanical and electrochemical cavitation generator to perform generation. The method for generating mechanical and electrochemical cavitation comprises: jetting water jet from a jet nozzle (20) having been immersed in water (W1); irradiating with ultrasonic waves (U1) a position at which, for flow cavitation generated accompanying the jetting of the water jet, the flow cavitation is expandable and the flow velocity of the flow cavitation reaches to a preset moving velocity or less; and thus generating multifunction cavitation (MFC) having both mechanical and electrochemical functions.
従来技術、競合技術の概要(英語) BACKGROUND ART
After an earthquake, particularly nuclear power utility and safety, such as a radioactive contamination problem has attracted attention. The emission of carbon dioxide in the thermal power generation is suppressed, does not depend on fossil resources in order to construct a sustainable society, effective use of renewable energy is required. In particular renewable energy devices are a large amount of utilizing the solar energy is very important, an applied technology is limited. To use the solar energy, for example, photovoltaic, solar, biomass, photosynthesis population and the like.
Is hydrogen, and carbon dioxide can be converted into a clean energy. The hydrogen reacts with oxygen, water and heat to generate power. Is hydrogen, generating energy efficiency is high, the motor vehicle applications in wide fuel power generation facility. An oxide semiconductor photocatalyst decomposes water directly in the electrode or light, sunlight to produce hydrogen and oxygen hydrogen production technology is lower in cost, aiming at the realization of the future hydrogen society Studies actively promoted.
The photocatalyst in the art, various light catalyst material (oxide semiconductor) is studied. Titanium oxide is low cost, as the material of the photoelectrode or photocatalysts to be applied to a solar energy conversion material has attracted attention. TiO2 is photocatalytic reaction, light having a wavelength of 350 nm (ultraviolet light) is provided with a feature is effective. However, only slightly in the ultraviolet light in sunlight have not been included, efficient energy conversion is, occupy half the solar energy utilize visible light is essential. Titanium oxide to embellish the visible light responsiveness studies have been made to develop a and, further, to modify the surface of metal have also been carried out studies (see Patent Document 1).
