| مستخلص: | A methane–benzene reaction was performed over Co/MFI prepared with an aqueous solution of Co(OAc)2and MFI zeolite. Co(OH)2was deposited on the MFI zeolite when the Co(OAc)2solution was stirred at 343 K in the presence of MFI. A decline of the h-peak in NH3TPD occurred during the loading of Co on MFI. Further thermal treatment at 573–773 K caused the spontaneous formation of the atomically dispersed Co species, which was observed with Co K-edge XAFS. The toluene formation rate of the catalyst prepared with Co(OAc)2was proportional to the Co loading and was higher than that prepared with Co(NO3)2due to the large amount of supported Co. |
