Methane dry reforming catalytic performance of Ce-based oxide recovered from spent Ni-MH batteries.

Abstract

We have studied resource recovery of anode materials of spent Ni-MH batteries. In this work, CH4 dry reforming catalytic properties of Ce-based oxide recovered from the anode materials were investigated. It was observed that the Ce-based oxide exhibited high CH4 conversion in CH4 dry reforming. This was attributable to metallic Ni formed by reduction of NiAl2O4 which co-existed with the Ce-based oxide samples.
