• thermal destruction of the mixture of the rhodium chalcogen halide and carbon carrier
(method #2);
• synthesis of the rhodium chalcogen halide over the carbon surface followed by thermal
destruction (method #3).
XPS and IR-spectroscopy data shows a formation of rhodium chalcogen halides in these
solids prepared by different methods.
We have found that productivity of acetic acid by carbon supported rhodium chalcogen
halides depends significantly on the carbon carrier and the method of the catalyst preparation.
Namely, the catalyst with highest productivity of the acetic acid is prepared by synthesizing
the rhodium chalcogen halide over the carbon support followed by thermal destruction. We
have also found that rhodium chalcogen halides over activated carbons are more active
comparing to fullerene supported catalysts.
