文摘
- •
Palladium catalysts supported on hydrogen titanate nanotubes (NT) were prepared.
- •
Pd(II) acetate was adsorbed onto dried and calcined NT supports from CH2Cl2 solutions.
- •
Supported Pd catalysts showed high activity in the Heck cross-coupling reaction.
- •
Stability of the catalysts depended on the Pd loading and the support water content.
- •
Leaching and readsorption of Pd species was observed during the Heck reaction.
