Catalyst-aided chemical processing method

Abstract

A catalyst-aided chemical processing method is a novel processing method having a high processing efficiency and suited for processing in a space wavelength range of not less than several tens of μm. The catalyst-aided chemical processing method comprises: immersing a workpiece in a processing solution in which a halogen-containing molecule is dissolved, said workpiece normally being insoluble in said processing solution; and bringing a platinum, gold or ceramic solid catalyst close to or into contact with a processing surface of the workpiece, thereby processing the workpiece through dissolution in the processing solution of a halogenide produced by chemical reaction between a halogen radical generated at the surface of the catalyst and a surface atom of the workpiece.

1 . A processing tool comprising:
 a synthetic resin base; and   a plated or coated film of platinum, gold or ceramic solid catalyst provided on a surface of the synthetic resin base.   
     
     
         2 . A processing tool comprising a mixture of a synthetic resin base and powder of platinum, gold or ceramic solid catalyst, with part of the powder being exposed on a surface of the synthetic resin base. 
     
     
         3 . A processing tool comprising:
 a non-woven fabric; and   powder of platinum, gold or ceramic solid catalyst carried in the interstices of the non-woven fabric.   
     
     
         4 . A processing tool comprising a non-woven fabric of fibers plated or coated with platinum, gold or ceramic solid catalyst.
