Patent ID: 7867940

Claim:
A method of preparing a supported catalyst, the method comprising: dissolving a cation exchange polymer in a solvent to prepare a solution containing the cation exchange polymer; mixing the solution with a catalytic metal precursor or a solution containing the catalytic metal precursor, to produce a mixture; heating the mixture to a temperature greater than 70° C. and less than 90° C., after adjusting a pH of the mixture to about 8, using a base, to obtain a resultant; adding a reducing agent selected from the group consisting of formaldehyde, formic acid, polyol, hydrazine, sodium borohydride, hydrogen gas, and mixtures thereof, to the resultant and stirring, to reduce the catalytic metal precursor and to obtain another resultant; mixing the obtained another resultant with a catalyst support; adding a precipitating agent to the mixed another resultant, to form precipitates; and filtering and drying the precipitates.
