文摘
- •
Y2Zr2O7 pyrochlore supports were successfully synthesized by different methods.
- •
Ni has stronger interaction with a support prepared by glycine-nitrate combustion.
- •
Ni has higher active surface area and smaller crystallite size on this support.
- •
Hence Ni/Y2Zr2O7-GNC exhibits superior activity and coke resistance.
- •
The support structures influence the reforming performance of the catalysts.
