Graphene oxide (GO) was utilized as an amphiphilic support to immobilize functionalized ionic liquid containing phosphotungstatic imidazolium (Im-PW) by an anion-exchange method. The physicochemical properties of the synthesized Im-PW/GO material were characterized by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, atomic force microscopy, scanning electron microscopy, transmission electron microscope, thermogravimetric analysis and contact angle measurements. In selective oxidation of benzyl alcohol to benzaldehyde, Im-PW/GO was determined to be an efficient triphase transfer catalyst, affording a high conversion (>90%) of benzyl alcohol and excellent selectivity (>99%) to benzaldehyde. Owing to the unique amphiphilic nature of GO support, the Im-PW/GO catalyst facilitated the contact between hydrophilic H₂O₂ and hydrophobic benzyl alcohol, therefore demonstrated superior catalytic activity to the similar catalyst supported on conventional SBA-15. Moreover, it was readily recovered and reused up to four times without any significant loss in terms of its activity.

氧化石墨烯（GO）被用作两亲载体，通过阴离子交换法固定化含磷钨酸咪唑鎓（Im-PW）的功能化离子液体。合成的Im-PW / GO材料的理化性质通过傅里叶变换红外光谱，X射线光电子能谱，原子力显微镜，扫描电子显微镜，透射电子显微镜，热重分析和接触角测量来表征。在苯甲醇选择性氧化为苯甲醛中，Im-PW / GO被确定为有效的三相转移催化剂，可提供高转化率（> 90％）的苯甲醇和出色的选择性（> 99％）转化为苯甲醛。由于GO载体具有独特的两亲性质，因此Im-PW / GO催化剂促进了亲水性H因此，与传统的SBA-15负载的相似催化剂相比，₂ O ₂和疏水性苄醇表现出优异的催化活性。而且，它很容易被回收并重复使用多达四次，而不会对其活性造成任何重大损失。
