Periana catalyst (the Catalytica system-(bpym)PtCl2) is known as the best homogeneous catalyst for methane functionalization so far; methane is converted with 90% conversion and 81% selectivity into methyl bisulfate. However, until now, many arguments still remain about not only the reaction mechanism, but also the role of the ligands. Recent research, (bpym) ligand is proved not to be mandatory for high activity; even it actually seems to be detrimental for the catalytic activity under the reaction conditions. Moreover, simple platinum salts are concluded be stable, selective and unprecedented active under reaction conditions superior to Periana catalyst. In our research, we synthesized successfully a new and efficient Pt-based homogeneous catalyst system having DMSO as a ligand. The catalytic activity of the new catalyst was investigated by performing the oxidation of methane (25bar) in the presence of fuming sulfuric acid. |
