The process for producing a polymer protective material free supported catalyst

An object of the present invention does not use a polymer protective material to reduce the performance of the catalyst, a polymer protective material free supported catalysts which can be sufficiently exhibited the effect of catalyst can be obtained more efficiently than the conventional method of manufacturing it is to provide a method. The process for producing a polymer protective material free supported catalyst according to the present invention, the nanoparticles are supported on the carrier, a method for producing a polymer protective material free supported catalyst containing no polymer protective material, synthesized nanoparticles as well as having a step 1 for supporting the nanoparticles on the carrier, step 1 contains an organic solvent carrier and carbon atoms having 2 or more reducing and containing a polymeric protection material a step 1a for heating the non mixture containing compound and the pure water becomes a raw material for synthesizing nanoparticles, and a step 1b of preparing a mixture containing no polymer protective material, a mixture of a mixture and a step 1b of step 1a and a step 1c of mixing and.
