The adsorption of propylene oxide (PO) onto MgO, ZnO and Al2O3was investigated by usingin situ-IR measurements. Detailed mechanisms for PO adsorption onto these metal oxides are proposed. It was found that the PO epoxide ring exhibits two opening tendencies, depending on the acid-base properties of the metal oxide. PO adsorbed onto MgO is preferentially opened at the O-C (1) bond. The epoxide ring provides two ways to open, at the O-C (1) or the O-C(2) bond on Al2O3. PO adsorbed onto ZnO showed no chemical adsorption on its surface.

In this paper, the PET depolymerization catalyzed by metal oxides (MgO, CdO, Cu2O,Sb2O3, MnO2, V2O5, SiO2,MoO3) under microwave irradiation were investigated, and the effects of acid-base on PET depolymerization was studied by acid-base scale method. The results indicated that the stronger the acidity or basicity of metal oxide was, the better the effects of catalytic depolymerization of PET appeared. Compared with alkali metal oxide, the catalytic effect of acid metal oxide to PET depolymerization was better.
