Regeneration of sintered Rh/ZrO 2 catalysts via Rh re-disper

发布时间：2021-01-04 14:39

　　Rh/ZrO₂ catalyst was prepared by the impregnation method and then aged in N2 atmosphere with 10% steam at 1050°C for 12 h. The regeneration of the aged catalyst was examined by slow cooling the catalyst in O₂ following preheating at 950°C. The as-prepared, aged, and regenerated catalysts were characterized by X-ray diffraction, Brunauer–Emmett–Teller specific surface area analysis, and（CO+NO） reaction activity tests, CO chemisorption, and transmission electron microscopy.
