Recovery of Nickel from Anode Materials of Spent Ni-MH Batteries and its Catalytic Property for CH4 Dry Reforming
Recovery process of Ni from anode materials of spent Ni-MH batteries and application of the resulting Ni to CH4 dry reforming catalyst were investigated, focusing on availability of Ni. NiO, which formed a solid solution with CoO, was successfully prepared from the waste by a series of chemical processes using aqueous solutions of HCl and NH3. The resulting NiO, which was reduced to Ni0, exhibited excellent CH4 conversion in CH4 dry reforming. Fromresults, it was concluded that the Ni recovered from anode materials of spent Ni-MH batteries was available for CH4 dry reforming catalyst.
