摘要
选用Zn、Ga、Sn为金属助剂制备了IrZn/SiO_(2)、IrGa/SiO_(2)和IrSn/SiO_(2)三种双金属催化剂,探讨不同金属助剂对Ir位点结构及催化丙烷脱氢性能影响。结果表明,催化剂中Ir位点的分散性极大影响催化性能。
Three bimetallic catalysts,IrZn/SiO2,IrGa/SiO2,and IrSn/SiO2 modified by different metal promoters(Zn,Ga,and Sn)were used to investigate the effects of different metal promoters on the structure of Ir active sites and propane dehydrogenation performance.A series of results showed that the dispersion of Ir sites significantly affected the catalytic performance.
