Catalyst carrier, catalyst and process for producing the same |
摘要 |
The present invention provides a catalyst carrier having excellent durability and capable of attaining high catalytic ability without increasing the specific surface area thereof, and a catalyst obtainable by using the catalyst carrier. The catalyst carrier of the present invention comprises a metal oxycarbonitride, preferably the metal contained in the metal oxycarbonitride comprises at least one selected from the group consisting of niobium, tin, indium, platinum, tantalum, zirconium, copper, iron, tungsten, chromium, molybdenum, hafnium, titanium, vanadium, cobalt, manganese, cerium, mercury, plutonium, gold, silver, iridium, palladium, yttrium, ruthenium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, and nickel. Moreover, the catalyst of the present invention comprises the catalyst carrier and a catalyst metal supported on the catalyst carrier. |
