| 中文摘要: |
| 通过调控钛酸四丁酯的浓度,制备了两种形貌的Cu2O/TiO2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Cu2O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,TiO2在Cu2O表面由膜状变为粒状。性能测试结果表明,与纯相Cu2O相比,膜状表面的Cu2O/TiO2复合物的抗菌性能有所提高,而粒状表面的Cu2O/TiO2复合物的抗菌性能略有降低。两种形貌的Cu2O/TiO2复合物对氨气的去除性能均好于纯相Cu2O,但粒状表面的Cu2O/TiO2复合物的除氨气性能优于膜状表面的复合物。 |
| 英文摘要: |
| The Cu2O/TiO2 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 TiO2 turns to granuliform on the surface of Cu2O nanoparticles while the TBOT concentration increased from 0.04% to 0.12%. On the other hand, compared with the pure Cu2O, the Cu2O/TiO2 composite with membranous surface exhibited better antibacterial properties, and the antibacterial properties of the sample with granuliform surface slightly reduction. Moreover, compared to pure Cu2O, the Cu2O/TiO2 composites with either membranous or granuliform surface performed more actively in ammonia removal, but the latter had a better removal performance than the former. |
