| 英文摘要 | The development of catalysts with high thermal stability, high catalytic activity and high cycling performance has been an important challenge in PET alcoholysis research. PET degradation is a surface interface controlled process, but PET as a dense solid with lower specific surface area severely reduces its degradation rate. Here, the high specific surface area (0.4-3.3 m(2)/g) and the large number of pores (0-17.5 nm) formed by the swelling of PET at high temperature were used to break the interfacial confinement between the reactants; then the rapid and complete degradation of PET was achieved under the multi-hydrogen bonding microenvironment formed by the multi-active site polyoxometalate (POM) catalysts K-10[M-4(H2O)(2)(PW9O34)(2)]-H2O (M = Zn, Mn, Cu, Ni, Co) and EG. Finally, accompanied by the attack of the transition metal active site on C= O of PET, 1.0 g of PET could be completely degraded in 5 min under the optimal reaction conditions (2.0 wt% of catalyst to PET, 240 C) and the bis(hydroxyethyl) terephthalate (BHET) yield of 92.8% was achieved within 8 min. Moreover, the catalyst could be recycled more than 30 times, which is very meaningful. In the same time, the mechanism of PET alcoholysis was investigated and proposed a mechanism of PET alcoholysis. |
