Abstract
Abstract The thermal decomposition courses of rhodium acetate, Rh(CH3COO)2, and chloride, RhCl3.3H2O, have been studied in hydrogen and nitrogen atmospheres, using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and infrared spectroscopy (IR). It was found that Rh acetate and chloride are similarly reduced to Rh° metal particles on heating near 120°C in H2 atmosphere. In N2 atmosphere, however, Rh acetate is reductively decomposed at 300–400°C to give Rh° metal particles, whereas Rh chloride is not decomposed into metal particles until the temperature is well above 800°C. Therefore, Rh acetate could be a better precursor compound for Rh metal catalysts, for its lower demand of heat supply than Rh chloride.
