The invention relates to a process for preparing a heterogeneous catalyst. The method comprises the steps of: (a) combining (i) a support, (ii) an aqueous solution of a noble metal compound and (iii) a C2-C18 thiol comprising at least one hydroxyl or carboxylic acid substituent for forming a wet particle and (b) removing water from the wet particle by drying followed by calcination to produce the catalyst. |
