Abstract

A series of Ni (10 wt %) supported on commercial yttrium stabilized zirconia (YSZ) catalysts have been prepared by different methods to evaluate the effect of Ni0 particle size on CO2 methanation activity. The reducibility and metal-support interaction were analyzed by H2-temperature programmed reduction (TPR) and in-situ x-ray absorption spectroscopy (XAS). The particle size and morphology were analyzed by TEM. A correlation of the catalytic activity with Ni0 particle size and metal-support interaction was found. The catalyst stability during time of stream (TOS) and under CO2 stream was performed by in-situ XAS. Apparent activation energy and reaction orders are determined for the most performing catalyst.
