This invention provides a catalytic composite for decomposing fats and oils, and a heating cooker having the catalytic composite mounted therein. The catalytic composite comprises a porous sheet made of ceramic fibers and/or metal fibers, and a catalyst. The catalytic composite is capable of decomposing oil grease or stains deposited on the inner wall of a heating cooker and cooking exhausts emitted in the process of cooking by oxidation, at relatively low temperatures.

Catalytic composite and a cooker having the same

A mixed oxide comprising oxides of Ce, Cu and Mn wherein an atomic ratio of Ce to a total atom number of Cu and Mn is from 1:2 to 2:1 and the metals are present in the mixed oxide in the oxide forms of CeO.sub.2 and Cu.sub.x Mn.sub.3-x O.sub.4 wherein x is a number larger than 0 (zero) and less than 3, which can catalyze the oxidation of organic materials.

Mixed oxide catalyst and coating or porous material comprising the same

An IR radiation heating element comprising a substrate and a coating film formed thereon from a coating composition for IR radiation heating which comprises an oxide of a transition metal or a mixed oxide of transition metals, ZrO.sub.2 and polyborosiloxane, which element has improved IR radiation efficiency when heated.

Nitrogen oxides removal method wherein nitrogen oxides are removed from a gas by bringing the gas into contact with a granulated material containing an alkali and cement material, active carbon and a binder. The active carbon promotes an absorption reaction between the alkali material and nitrogen oxides, the cement material provides a porous but strong structure to the material, and the binder permits longer use of the material in a wide range of conditions.
