We employed a strategy combining static and dynamic combination strategy to enhance both product selectivity and catalyst stability during propane dehydrogenation. Static Bi doping facilitates electron transfer from Bi to Co, promoting C₃H₈ conversion to C₃H₆ and mitigating undesired side reactions. CO₂ acts as a dynamic decarburizing agent that efficiently inhibits coking while prolonging catalyst lifespan.

在丙烷脱氢过程中通过静态双掺杂和动态痕量 CO2 共进料提高负载型钴催化剂的选择性和稳定性

我们采用了静态和动态相结合的策略来提高丙烷脱氢过程中的产品选择性和催化剂稳定性。静态 Bi 掺杂促进电子从 Bi 到 Co 的转移，促进 C₃H₈ 转化为 C₃H₆ 并减轻不需要的副反应。CO₂ 作为一种动态脱碳剂，可有效抑制焦化，同时延长催化剂的使用寿命。
