Abstract: There is disclosed a method for producing a metal oxide, which comprises the steps of: dissolving a metal organic compound (e.g. a metal organic acid salt, a metal acetylacetonato complex, and a metal alkoxide having an organic group with 6 or more carbon atoms) in a solvent to provide a state of solution, applying the solution onto a substrate, drying the solution, and subjecting the resultant substrate to irradiation with a laser light of a 400 nm or less wavelength, to form a metal oxide on the substrate. According to that method, a metal oxide can be produced without applying a heat treatment at a high temperature of the degree adopted in the conventionally known application thermal decomposition method.

Abstract: A method for producing a metal oxide, comprises the steps of: dissolving a metal organic compound (e.g. a metal organic acid salt, a metal acetylacetonato complex, or a metal alkoxide having an organic group with 6 or more carbon atoms) in a solvent to provide a state of solution, applying the solution onto a substrate, drying the solution, and subjecting the resultant substrate to irradiation with a laser light of a 400 nm or shorter wavelength, to form a metal oxide on the substrate. According to this method a metal oxide can be produced without applying a heat treatment at a high temperature to the degree adopted in the conventionally known application thermal decomposition method. A minute pattern can be obtained by irradiation with a laser light according to a pattern shape or through a mask pattern.

Abstract: PURPOSE:To enable production of a long-life electrode which is dense, has high adhesiveness and has decreases internal stress of electrodeposition by coating an underlying layer contg. Pt and Pd oxide, intermediate layer consisting of alpha-PbO2 and coating layer of beta-PbO2 contg. a fibrous material successively on a corrosion resistant metallic substrate. CONSTITUTION:A sheet, perforated sheet, etc., consisting of Ti, Zr, Nb, Ta, or the alloys thereof, etc., are used as the substrate and the sticking area is preferably increased by subjecting the surface thereof to a ruggedness forming treatment. The underlying layer contg. the Pt and/or Pd oxide for protecting the substrate and improving the adhesiveness to the intermediate layer is formed on the surface of such substrate. The intermediate layer consisting of the alpha-PbO2 to play mainly the role of connection is the formed thereon. Further, the beta-PbO2 coating layer contg. the granular or fibrous material which is electrochemically inert and has corrosion resistance is formed on the surface thereof. The effect of dispersing the internal stress of electrodeposition of the beta-PbO2 layer is obtd. by incorporating the above-mentioned granular or other material into the coating layer.

Abstract: PURPOSE:When a gas diffusion electrode is manufactured by coating a reaction layer containing a catalyst laminatedly on a hydrophobic porous gas transmission layer provided with a collector, to make the manufacture of the electrode easy by using lead dioxide as the catalyst in the reaction layer. CONSTITUTION:A gas diffusion electrode is constructed with a hydrophobic porous gas transmission layer 1, a reaction layer 2 containing a material consisting of lead dioxide carried on carbon black, and a collector 3. As for the collector 3, a copper mesh of 32 in mesh number is used, and as for raw materials of the hydrophobic porous gas transmission layer 1 a mixture of powder composed of hydrophobic acetylene black mixed with 40wt.% of PTFE is used. As for raw materials of the reaction material containing a catalyst to be contacted to an electrolyte, a mixture of respective equal amounts of extra pure reagent lead dioxide powder containing 20wt.% of PTFE and hydrophobic acetylene black powder containing 30wt.% of PTFE is used. Thereby a gas diffusion electrode of high oxidation efficiency and hard to generate deactivation due to poison can be obtained.
