文摘
- •
AuPd/TiO2 were synthesized by one-step FSP method and reduced at 40 and 500 °C.
- •
The nanoparticles were AuPd alloy for both FSP-AuPd/TiO2 R40 and R500.
- •
Reduction at 500 °C homogenize the composition of individual AuPd nanoparticles.
- •
Higher reaction rate was obtained on AuPd/TiO2 R40 than on AuPd/TiO2 R500.
- •
The highest yield of 1-heptene was 93% on AuPd/TiO2 R40.
