以纳米片（S）和纳米片（P）γ-Al_2O_3为载体，制备了Ni/γ-Al_2O_3催化剂。Ni/Al_2O_3-S催化剂具有较好的活性和稳定性，而Ni/Al_2O_3-P催化剂活性略低，稳定性差。Ni/Al_2O_3-S催化剂中Ni纳米颗粒的尺寸要小得多，这可能是催化剂活性差异的原因。Ni/Al_2O_3-S催化剂具有较好的抗烧结和抗积炭性能，提高了催化剂的稳定性。
Ni catalysts supported on nanosheet (S) and nanoplate (P) γ-Al2O3have been successfully synthesized for carbon dioxide (CO2) reforming of methane. The Ni/Al2O3-S catalyst possessed excellent activity and stability whereas the Ni/Al2O3-P catalyst exhibited slightly lower activity and much worse stability. The Ni/Al2O3-S catalyst displayed much smaller size of Ni nanoparticles, which may explain the difference in activity. The Ni/Al2O3-S catalyst possessed enhanced anti-sintering and anti-coke properties, which would lead to an improved stability.
