采用水热法以TiO2和石墨烯为原料制备了石墨烯杂化的钛酸纳米管复合光催化材料。首次将石墨烯修饰的钛酸纳米管涂布在电极上,研究了其在可见光照射下电化学方法降解罗丹明-B的性能。结果表明,制备的该系列复合光催化剂都具有良好的可见光响应和杰出的电化学降解罗丹明-B表现。其中,石墨烯含量为5%的样品具有最优的活性。另外通过实验发现,较低的水热反应温度制备的光催化剂的催化性能更佳。
Hydrothermal method using TiO2 and graphene as raw materials prepared graphene hybrid titanate nanotube composite photocatalytic materials. The graphene modified titanate nanotubes were coated on the electrodes for the first time and their properties of electrochemical degradation of rhodamine-B under visible light irradiation were studied. The results show that the prepared composite photocatalyst has good visible light response and excellent electrochemical degradation of rhodamine-B. Among them, samples with graphene content of 5% had the best activity. In addition, it was found through experiment that the photocatalyst prepared by the lower hydrothermal reaction temperature has better catalytic performance.
