文摘
- •
Ag/BaCO3 catalyst was prepared by the reduction-deposition method.
- •
Ag/BaCO3* catalyst exhibits better catalytic performance and good durability.
- •
Smaller Ag crystallite size is more effective for epoxidation of propylene.
- •
Low reduction temperature and calcination temperature get small Ag crystallite size.
- •
Epoxidation of propylene over Ag/BaCO3* catalyst follows Rideal–Eley mechanism.
