摘要
综述了石墨烯-二氧化钛复合光催化材料的发展进程、合成方法、优点和缺点。通过纳米石墨烯掺杂,添加EDTA和甲醇使纳米木质纤维素基磁性中空材料光催化活性提高,但也有可见光利用率低和定量回收和再利用难的问题。因此,在对磁性中空光催化材料未来发展方向进行展望时,提出应对磁性中空光催化材料进行优化,以提高中空材料对可见光利用率和定量回收和再利用的能力。
The development process,synthesis methods,advantages and disadvantages of graphene-titanium dioxide composite photocatalytic materials are reviewed.The photocatalytic activity of nano-sized lignocellulose-based magnetic hollow materials was improved via doping with nano-graphene and adding EDTA and methanol.However,there were also problems such as low visible light utilization rate and difficult quantitative recovery and reuse.Therefore,when the future development direction of magnetic hollow photocatalytic materials is prospected,it is proposed that the magnetic hollow photocatalytic materials should be further optimized to improve the utilization rate of visible light and the quantitative recovery and reuse ability of photocatalytic materials.
