Catalyst formed by spraying a titanium hydroxide material

Abstract

A catalyst includes a catalytically active composition produced by thermal spraying of a spraying material onto a support body. The spraying material includes a titanium hydroxide reactive precursor of at least one component of the catalytically active composition, and the titanium hydroxide reactive precursor converts to form the at least one component.

We claim:  
     
         1 . A catalyst, comprising: 
 a catalytically active composition produced by thermal spraying of a spraying material onto a support body;    said spraying material including a titanium hydroxide reactive precursor of at least one component of said catalytically active composition; and    said titanium hydroxide reactive precursor converted to form said at least one component.    
     
     
         2 . The catalyst according to    claim 1   , wherein said titanium hydroxide reactive precursor is converted before spraying to form said at least one component.  
     
     
         3 . The catalyst according to    claim 1   , wherein said titanium hydroxide reactive precursor is converted after spraying to form said at least one component.  
     
     
         4 . The catalyst according to    claim 1   , wherein said catalytically active composition includes multinary compounds.  
     
     
         5 . The catalyst according to    claim 1   , wherein said catalytically active composition includes ternary metal oxides.  
     
     
         6 . The catalyst according to    claim 1   , wherein said catalytically active composition has a BET surface area of from 40 to 100 m 2 /g.  
     
     
         7 . The catalyst according to    claim 1   , wherein said catalytically active composition has a BET surface area of from 50 to 70 m 2 /g.  
     
     
         8 . The catalyst according to    claim 1   , wherein said support body has a thickness of less than 1 mm.  
     
     
         9 . The catalyst according to    claim 1   , wherein said support body has a thickness of less than 100 μm.  
     
     
         10 . The catalyst according to    claim 1   , wherein said support body is formed of a chromium-aluminum steel.
