摘要

Abstract

A series of oxides (La

CoO

4±y

) with perovskite-like structure were prepared by the Pechini sol-gel method for dry reforming of methane reaction (DRM). The prepared catalysts were characterized by BET

XRD

TGA

-TPR and SEM. Experimental results indicate that the addition of Ce can impact both sample morphology and catalytic performance significantly compared with La

CoO

catalyst

and LaCeCoO

presented the highest catalytic ability among all the samples. The Ce addition tends to increase the specific surface area of La

2-x

CoO

from 0.2 to 8.5 m

suggesting that LaCeCoO

catalyst contained more well-dispersed active sites and more space to reaction. Moreover

the catalytic performance and anti-coking ability were substantially improved after Ce addition during DRM

which may be attributed to the decrease of LaCoO

particle size and growth of oxygen storage capacity

respectively.
