Abstract

A method for producing silver nanowires, wherein silver is precipitated in the form of wires by reduction in an alcohol solvent into which a silver compound is dissolved. The precipitation is carried out in an alcohol solvent into which a chloride, a bromide, an alkali metal hydroxide, an aluminum salt and an organic protection agent, which is a copolymer having a polymer composition of vinyl pyrrolidone and a diallyldimethylammonium salt monomer, are dissolved. The molar ratio of the total amount of Al in the aluminum slat to be dissolved in the solvent to the total amount of hydroxide ions in the alkali metal hydroxide to be dissolved in the solvent, namely Al/OH is set to 0.01-0.40. The molar ratio of the amount of hydroxide ions in the alkali metal hydroxide to be dissolved in the solvent to the total amount of Ag in the silver compound to be dissolved in the solvent, namely OH/Ag is set to 0.005-0.50. Consequently, thin and long silver nanowires, which have an average diameter of 50 nm or less and an average length of 10 μm or more and are suitable for the production of a transparent conductor, are stably produced by this method for producing silver nanowires.

Abstract

The purpose of the present invention is to provide a catalyst, etc. having a low reaction start temperature at which a self-heating function appears, and whereby carbon accumulation is suppressed even when reaction is repeated. This catalyst comprises a CeZr-based oxide, silicon, and a catalytically active metal, and is characterized in that the CeZr-based oxide satisfies the formula CexZryO2 (x + y = 1), and the silicon satisfies the mole ratios 0.02 ≤ Si/Zr and 0.01 < Si/(Ce + Zr + Si) < 0.2. This catalyst is capable of lowering the initial reduction temperature for causing oxygen vacancies, and, according to the catalytically active metal, enables reductive activation even at approximately 20°C, at which there is no need for heating. In repeated hydrogen generation reactions, since deposition of generated carbon on the catalyst surface can also be suppressed, and catalytic activity can be prevented from decreasing, the performance of the catalyst can be maintained for a long time.

Abstract

A method wherein a metal film composed of Cu, In and Ga is formed and then the metal film is selenized is known as a method for obtaining a film-like crystal of a chalcogen compound. This method, however, involves problems of film uniformity and productivity. Although a film-like crystal of a chalcogen compound with high uniformity can be obtained by a low-cost method for obtaining nanoparticles containing Cu, In, Ga and Se, the resistivity of the film-like crystal of a chalcogen compound is high since a large amount of carbon is contained in the chalcogen compound and thus the film-like crystal of the chalcogen compound does not have characteristics sufficient for applications such as solar cells. Specifically disclosed is a chalcogen compound powder which contains Cu, In, Se and optionally Ga, has an average particle diameter (D50) of less than 0.5 μm, and has a carbon content in the powder of 0.2% or less. The chalcogen compound powder is obtained by heating a metal hydroxide powder having an average primary particle diameter of 0.3 μm or less and one or more substances selected from among selenium and selenium compounds to a temperature not less than 220˚C in a reducing gas.
