文章摘要
Abstract: Propylene is a significant basic material for petrochemicals such as polypropylene, propylene oxide, etc. With abundant propane supply from shale gas, propane dehydrogenation (PDH) becomes extensively attractive as an on-purpose propylene production route in recent years. Nitrogen-doped carbon (NC) nanopolyhedra supported cobalt catalysts were synthesized in one-step of ZIF-67 pyrolysis and investigated further in PDH. XPS, TEM and N2 adsorption-desorption were used to study the influence of carbonization temperature on as-prepared NC supported cobalt catalysts. The temperature is found to affect the cobalt phase and nitrogen species of the catalysts. And 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.
