主 题:Propane dehydrogenation ZIF-67 Nitrogen-doped carbon Cobalt
摘 要:Propylene is a significant basic material for petrochemicals such as polypropylene,propylene oxide,*** abundant propane supply from shale gas,propane dehydrogenation(PDH)becomes extensively attractive as an on-purpose propylene production route in recent ***-doped carbon(NC)nanopolyhedra supported cobalt catalysts were synthesized in one-step of ZIF-67 pyrolysis and investigated further in ***,TEM and N_(2) adsorption-desorption were used to study the influence of carbonization temperature on as-prepared NC supported cobalt *** temperature is found to affect the cobalt phase and nitrogen species of the *** the positive correlation was established between Co0 proportion and space time yield of propylene,indicating that the modulation of carbonization temperature could be important for catalytic performance.
