The invention provides a method for oxidizing carbon monoxide present in an oxygen-containing gas phase to carbon dioxide which comprises: adsorbing the carbon monoxide onto porous silica; and irradiating the porous silica with ultraviolet ray. In the invention, mesoporous silica or amorphous silica is used as the porous silica. In particular, silica gel that is amorphous silica is preferably used.

Lithium ion secondary battery, cathode active material therefor and production thereof

A process for producing a lithium manganese oxide with a spinel structure for use as a cathode material of an organic electrolyte lithium ion secondary battery, which comprises: mixing at least one lithium compound selected from the group consisting of lithium hydroxide and lithium carbonate with manganese dioxide in a solvent consisting essentially of water or an aliphatic lower alcohol having from 1 to 3 carbon atoms or a mixture thereof, optionally in the presence of at least one organic acid selected from the group consisting of formic acid and acetic acid; allowing the resultant mixture to form a gel-like mixture; and drying the gel-like mixture as required; and calcining the resulting product.

Process for producing lithium manganese oxide with spinel structure

A process for producing a lithium manganese oxide which has a formula of Li.sub.x MnO.sub.2 in which x is between 0.1 and 1 and which is suitable for use as a 3 volt cathode material, which comprises mixing at least one lithium compound with at least one manganese compound at a Li/Mn atomic ratio of 0.1-1 in a solvent selected from an aliphatic lower alcohol having from 1 to 3 carbon atoms, water and a mixture of the alcohol and water, allowing the resultant mixture to form a gel-like mixture, drying the gel-like mixture as required, and calcining the resulting product in an oxidative atmosphere at a temperature of 200-350.degree. C.

Process for producing lithium manganese oxide suitable for use as

A process for production of a glass substrate coated with a patterned Nesa glass membrane which comprises, in sequence:

Process for production of glass substrate coated with finely patterned

There is disclosed a method of producing a transparent zinc oxide film having an even thickness especially useful as a ultraviolet rays cut off. The method comprises applying a solution of an organic zinc compound selected from the group consisting of a zinc salt of a fatty acid of 3-7 carbons and a chelate compound of a diketone of 5-8 carbons in an organic solution on a substrate, and then baking the resultant coating at temperatures of 300.degree.-600.degree. C. It is preferred that the solution of an organic zinc compound further contains at least one organometallic compound of a metal selected from the group consisting of aluminum, indium, tin and titanium.
