摘要
通过调控钛酸四丁酯的浓度,制备了两种形貌的Cu_2O/TiO_2复合物。利用X射线衍射(XRD)、傅里叶变换红外(FTIR)光谱、扫描电镜(SEM)和透射电镜(TEM)对样品进行了表征,并将复合材料的抗菌性能和除氨气性能与Cu_2O进行了详细比较。结果表明,钛酸四丁酯的浓度由0.04%变为0.12%时,TiO_2在Cu_2O表面由膜状变为粒状。性能测试结果表明,与纯相Cu_2O相比,膜状表面的Cu_2O/TiO_2复合物的抗菌性能有所提高,而粒状表面的Cu_2O/TiO_2复合物的抗菌性能略有降低。两种形貌的Cu_2O/TiO_2复合物对氨气的去除性能均好于纯相Cu_2O,但粒状表面的Cu_2O/TiO_2复合物的除氨气性能优于膜状表面的复合物。
The Cu 2O/TiO 2 composites with two different morphologies were synthesized through adjusting the concentration of tetra-n-butyl titanate(TBOT),and were subsequently characterized by means of X-ray diffraction(XRD),fourier transform infrared(FTIR)spectroscopy,scanning electron microscopy(SEM)and transmission electron microscopy(TEM).The resultant composites’antibacterial properties and ammonia removal performances were also determined by the experiment.It has been observed that the membranous TiO 2 turns to granuliform on the surface of Cu 2O nanoparticles while the TBOT concentration increased from 0.04%to 0.12%.On the other hand,compared with the pure Cu 2O,the Cu 2O/TiO 2 composite with membranous surface exhibited better antibacterial properties,and the antibacterial properties of the sample with granuliform surface slightly reduction.Moreover,compared to pure Cu 2O,the Cu 2O/TiO 2 composites with either membranous or granuliform surface performed more actively in ammonia removal,but the latter had a better removal performance than the former.
