基于石墨烯优异的电子传输特点，本文以石墨烯为载体，醋酸锌为半导体前驱体，通过水热法制备了氧化锌／石墨烯复合材料。对所合成的复合材料进行了 X 射线衍射（XRD）、红外光谱（FT-IR）、扫描电子显微镜（SEM）、拉曼光谱（Raman）、氮气吸脱附等温曲线及光催化性能测试。结果表明：氧化锌均匀复合在石墨烯表面，两者形成了有效的界面耦合。得益于氧化锌在水热反应过程中形成的高结晶度及与石墨烯之间的界面耦合作用，电子可从氧化锌的价带直接传向石墨烯，因此该复合材料的光降解效率达到了89．84％，相比于商用二氧化钛有了显著提高（47．68％），其光降解一级反应速率常数达到0．012 min－1。这种新颖的、具有优异光催化性能的氧化锌／石墨烯复合材料在光催化领域具有较高的潜在应用价值，为构筑其他石墨烯基半导体复合材料提供了新的思路。

Due to its excellent electron transport property,graphene-based materials have been explored in a wide range of applica-tions.The zinc oxide/graphene (ZnO/graphene)composite photocatalyst,where ZnO was wrapped by graphene nanoshells,was prepared via a rapid hydrothermal method,by the precursor solution of Zn(CH3 COO)2 and graphene.The ZnO/graphene com-posite material was characterized in detail by X-ray diffraction (XRD),FT-IR,scanning electron microscopy (SEM),Raman spectra,N2 adsorption-desorption and the photodegradation of Rhodamine B.The results show that the surface of graphene is covered uniformly by ZnO,and ZnO can stably disperse due to the interfacial interactions in graphene.The interfacial couplings benefit the hole-electron separation and the charge transport,allowing more opportunities for electrons to participate to form ac-tive oxygen species,which are capable of photodegradation RhB.The photocatalytic experiments indicate that the photodegrada-tion efficiency on RhB shows much higher compared to that of TiO2 and the first-order kinetics value is 0.012 min-1 .This novel high photocatalytic performance ZnO/graphene composite will potential applications in photocatalysis and the strategy offers new ideas for fabricating other graphene-based semiconductor composite materials.
