Separation and reusability had been main problems for the using of polyethylene glycol (PEG) as phase transfer catalysts (PTCs). To solve these problems, PEG was firstly and successfully grafted on graphene oxide (GO) using BF3·C2H5OC2H5 as Lewis acid catalyst. The solid GO-PEG composites were systemically investigated by characterization techniques (TG, FT-IR, XPS, ICP-AES etc.) and then applied...
