The use of various types of multi-walled carbon nanotubes in the synthesis of bismuth oxybromide semiconductors via imidazolium ionic liquid was studied in detail. The effect of the MWCNT shape, specific surface area, and various diameters on the morphology, surface properties and photoactivity of the Bi-based composites has been investigated for the first time. So far, the literature has only shown the enhancement of photocatalytic activity of composites containing MWCNT; however, our research shows a broader view of the issue. The photocatalytic activity of the individual composites under UV–Vis irradiation was assessed by the degradation of various micropollutants, showing the diversity of properties of the obtained composites. It is also significant that in the composite system, the imidazolium ionic liquid played a crucial role in the formation of microspheres and acted as a dispersing agent, leading to an even distribution of MWCNTs on the surface of the spherical bismuth oxybromide.

多壁碳纳米管特性对咪唑鎓离子液体合成铋基复合材料光催化活性的影响



详细研究了各种类型的多壁碳纳米管在咪唑鎓离子液体合成溴氧化铋半导体中的应用。首次研究了多壁碳纳米管的形状、比表面积和不同直径对铋基复合材料的形貌、表面性能和光活性的影响。迄今为止,文献仅显示了含有MWCNT的复合材料光催化活性的增强;然而,我们的研究显示了对这个问题的更广泛的看法。通过各种微污染物的降解来评估单个复合材料在紫外-可见光照射下的光催化活性,显示出所获得的复合材料性能的多样性。同样重要的是,在复合体系中,咪唑鎓离子液体在微球的形成中发挥了至关重要的作用,并充当分散剂,导致多壁碳纳米管均匀分布在球形溴氧化铋的表面。
