| 英文摘要 | direct conversion of syngas into hydrocarbons with high selectivity remains a challenge. herein, we report the synthesis of a core-shell-structured catalyst constituting cr-zn oxide as the core and sapo-34 as the shell for the conversion of syngas into hydrocarbons with high selectivity. a sio2 layer was sandwiched between the core and the shell to prevent damage to the core during shell synthesis. furthermore, the intermediate sio2 layer acted as a si source for the formation of the shell. the prepared catalyst displayed considerably higher selectivity toward the production of c-2-c-4 hydrocarbons (66.9%) than that of methanol and methane. the findings show the potential of the prepared core-shell-structured catalyst in the one-step production of hydrocarbons, such as liquefied petroleum gas, from syngas. however, further optimization of the catalyst is necessary to achieve higher performance.
