The present invention is an organoruthenium compound for a chemical vapor deposition raw material, including dodecacarbonyl triruthenium represented by the following chemical formula, wherein the iron (Fe) concentration is 1 ppm or less. The DCR in the present invention can be produced by obtaining crude DCR by directly carbonylating ruthenium through allowing a ruthenium salt and carbon monoxide to react with each other and by purifying the crude DCR by a sublimation method. In the synthesis step, the concentration of Fe in the obtained crude DCR is preferably set at 10 ppm or less.

The present invention is a hydrogen combustion catalyst including a catalyst metal supported on a carrier composed of an inorganic oxide, wherein a functional group having at the end thereof at least an alkyl group having three or less carbon atoms is bonded by substitution to each of a certain fraction or the whole of the hydroxyl groups on the surface of the carrier. The functional group bonded to each of a certain fraction or the whole of the hydroxyl groups on the surface of the carrier is preferably an organic silane. The hydrogen combustion catalyst according to the present invention is capable of maintaining the activity thereof even when a hydrogen-containing gas, a treatment object, contains a water content equal to or less than the saturated water vapor content and the reaction temperature is set at or around room temperature, namely, at 0 to 40° C.

摘要:
A method for supporting a catalytic metal on the surface of a carrier by bringing an aqueous catalytic metal salt solution into contact a porous carrier. The method includes the steps of: impregnating the carrier with a liquid hydrophobic organic compound before bringing the aqueous catalytic metal salt solution into contact with the carrier, and drying the impregnated carrier to volatilize the hydrophobic organic compound on the surface of the carrier, followed by bringing the carrier into contact with the aqueous catalytic metal salt solution; and then bringing a reducing agent into contact with the catalytic metal salt on the surface of the carrier to reduce the catalytic metal salt to undergo insolubilization treatment. The catalytic component is supported in a region from the surface of the carrier to a depth of 50 μm or more and 500 μm or less. The supported state of the catalytic component is made controllable, and the catalytic component can be supported in the inner part of the carrier with a suitable depth.
