Synthesis of Carbon Nitride Nanosheet/Bismuth Titanate Nanorod Hybrid and Its Photocatalytic Performance
以硝酸铋和钛酯为原料，结合氮化碳纳米片，通过液相溶液化学工艺，成功制备了具有一维纳米棒钛酸铋/二维氮化碳纳米片光催化复合材料。利用X射线衍射(XRD)、透射电子显微镜(TEM)、紫外-可见光吸收光谱(UV-Vis)等技术对样品的晶体结构、形貌及光吸收性能等进行了表征分析。以RhB为目标化合物，评价了其可见光催化活性。研究结果表明，通过液相溶液化学工艺制备了一维钛酸铋纳米棒均匀分散于二维氮化碳纳米片上, 其氮化碳/钛酸铋复合催化材料对光的吸收边为400-500nm。在可见光条件下，照射120min，其氮化碳/钛酸铋复合催化材料对RhB溶液的降解效率达到了92%。
In this work, the two-dimentional (2D) carbon nitride nanosheet/one-dimentional (1D) bismuth titanate nanorod hybrids as photocatalysts were fabricated by the solution-phase chemical process using bimuth nitrate and titanium t-butoxide as well as 2D carbon nitride nanosheet. XRD, TEM and UV-Vis spectra were employed to characterize the phase structure, morphology and optical property of the sample. Using the degradation of RhB, the photocatalytic performance of the carbon nitride/bismuth titanate photocatalysts with the absorption edge of 400-500nm were investigated. The obtained results presented that the decolorization efficiency of RhB solution reached about 92% under the visible-light irridiation for 120 min.
