  • Patent number: 8142898
    Abstract: The present invention relates to an electrocatalytic coating and an electrode having the coating thereon, wherein the coating is a mixed metal oxide coating, preferably ruthenium, titanium and tin or antimony oxides. The coating uses water as a solvent that provides for a smoother surface than alcohol based solvents. The electrocatalytic coating can be used especially as an anode component of an electrolysis cell and in particular a cell for the electrolysis of aqueous chlor-alkali solutions.

  • Publication number: 20120037512
    Abstract: Electrodes for electrolysis of water, for encouraging growth of algae and aerobic bacteria, for removing suspended solids from wastewater during treatment, or for rendering water sterile and potable have a concrete coating over a metallic or carbon fibre core. The coating is from 2 to 50 mm thick; preferably 5 to 25 mm thick. Preferably, a DC current passed between the immersed electrodes periodically reversed but there is no visible “rusting” at the anode if the DC current is steady. The resistive nature of the concrete tends to suppress concentrations of current upon the electrode surface.

  • Publication number: 20110315551
    Abstract: An electrode for active oxygen species comprising a conductive component with a polymer membrane of a metal porphyrin complex formed on the surface is disclosed. The electrode for active oxygen species can detect active oxygen species such as superoxide anion radicals, hydrogen peroxide, and .OH and other active radical species (NO, ONOO—, etc.) in any environment including in vivo environment as well as in vitro environment. The electrode thus can be used for specifying various diseases and examining active oxygen species in food or in water such as tap water and sewage water.

  • Publication number: 20110308939
    Abstract: The present invention relates to an electrode that includes an electrically conducting substrate based on a valve metal having a main proportion of titanium, tantalum or niobium, and an electrocatalytically active coating comprising up to 50 mol % of a noble metal oxide or noble metal oxide mixture and at least 50 mol % of titanium oxide. The coating includes a minimum proportion of oxides of anatase structure determined by a ratio of the signal height of the most intensive anatase reflection in an x-ray diffractogram (CuK? radiation) after subtraction of a linear background to the signal height of the most intensive rutile reflection in the same diffractogram, wherein the ratio is at least 0.6.
