Abstract
A series of γ-Al2O3 modified with different content of polyethylene glycol (PEG) was prepared by a reverse precipitation method. The phase transformation, thermal stabilization and the morphology of PEG-modified γ-Al2O3 was studied by XRD, BET and TEM, respectively. The results showed that the γ-Al2O3 with 1mol% PEG-modified has the excellent thermal stabilization after calcined at 1100°C for 3h. With the content of PEG increasing, the surface area of γ-Al2O3 was reduced gradually. Simultaneity, the γ-Al2O3 phase was transferred to θ-Al2O3 with the surface area 92 m2g-1 and a pore volume of 0.77 cm3g-1. The high surface area maintained at such high treatment temperature shows the 1mol% PEG-modified γ-Al2O3 prepared by reverse precipitation method can be applied in the automotive three-way catalyst support.
