    Preparation of wood-based g-C3N4/TiO2 composite coating and characterization of its photocatalytic properties

    • 摘要: 为改善木材易污染,易霉变的缺点,采用真空浸渍和液相沉淀法,将g-C3N4/TiO2复合涂层负载于木材表面,对木材进行功能化改良,赋予木材光催化自清洁功能。使用扫描电镜、能谱仪、X射线衍射、傅里叶红外光谱表征样品的表观形貌、相结构等。以罗丹明B为目标污染物,利用UV-VIS分光光度计测量降解效率,检测负载g-C3N4/TiO2复合涂层的木质基材光催化性能。结果表明: g-C3N4/TiO2复合涂层成功负载于木材表面,g-C3N4与TiO2相互掺杂有效地提高了两者的光催化活性,负载g-C3N4/TiO2复合涂层的木质基材具有一定的光催化功能。

       

      Abstract: To improve the drawback of wood that is easily polluted and mildewed and impart self-cleaning property to the wood products, we made functional improvements to wood. The g-C3N4/TiO2 composite coating was grown on wood surface via vacuum impregnation and liquid phase precipitation method. The g-C3N4/TiO2 composite coating was characterized by scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR). The photocatalytic activity of g-C3N4/TiO2 composite coated wood was measured by UV-VIS spectrophotometer with Rhodamine B as a target pollutant. The results indicated that g-C3N4/TiO2 composite coating was successfully immobilized on the surface of wood and the doping of g-C3N4 and TiO2 effectively improved its photocatalytic activity. The wood surface is successfully endowed with self-cleaning properties.
