摘要：
Ir catalysts supported on Ce0.9La0.1O2 nanorods and nanoparticles were comparatively investigated for syngas production from methane dry reforming reaction. The exposure of active {110} and {100} crystal planes in the Ir/Ceo Ce0.9La0.1O2- nanorods catalysts contributed to the stronger redox property and more oxygen vacancy than those in the Ir/Ce0.9La0.1O2-nanoparticles catalysts. These advantages facilitated activation and transformation of methane and carbon dioxide, giving an enhanced performance of methane dry reforming reaction over the Ir/Ce0.9La0.1O2-nanorods catalysts. The work demonstrated significant influences of support morphologies in obtaining stable catalysts for methane dry reforming reaction.
