| Abstract: | Two new water-soluble metal complex ionic compounds [Pt(NH3)4](OH)2.2H2O and [Pd(NH3)4](OH)2 were synthesized. The structure of the product was characterized by elemental analysis, infrared spectroscopy and 1H-NMR. The thermal decomposition characteristics were tested by thermogravimetric-differential thermal (TG-TDA) to investigate thermal stability of the complex. The thermal stability performance of the compound and the comparative evaluation of the performance of the prepared DOC catalyst were carried out. The results showed that the TG-DTA test showed that the decomposition temperature of the two complexes was in the range of 200~400°C, the thermal stability was good, and the prepared DOC catalyst had good catalytic activity. |
