High-surface-area CeO2 materials have been well known as promoters for noble metals (Pd, Pt, and Au). CeO2 is now being deployed as a low-temperature catalyst in the decomposition of VOCs. This is because of the increase in metal dispersion and CeO2 participation in the reaction [147]....
The methanation catalysts generally consist of two parts: (1) transition/noble metal, i.e., Ni, Fe, Co, Ru or Pd, acts as an active site [2]; and (2) (mixed) metal oxide, i.e., Al2O3, SiO2, ZrO2, CeO2, La2O3, MgO, TiO2, carbon materials and zeolites, act as a suppor...
