A novel method for fast and continuous preparation of superfine titanium dioxide nanoparticles in microfluidic system
文献摘要：
Previously we had developed a microfluidic system that can be easily fabricated by bending a stainless-steel tube into large circular loops.In this study,a fast and continuous preparation method for superfine TiO2 nanoparticles(TiO2-NPs)was developed for the aforementioned microfluidic system.The pro-posed method can yield anatase TiO2 in 3.5 min,in contrast to the traditional hydrothermal reaction method,which requires hours or even days.Different reaction conditions,such as reaction temperature(120-200℃),urea concentration(20-100 g/L),and tube length(5-20 m)were investigated.X-ray diffrac-tion and Brunauer-Emmett-Teller analysis indicate that the as-prepared TiO2-NPs have crystalline sizes of 4.1-5.8 nm and specific surface areas of 250.7-330.7 m2/g.Transmission electron microscopy images show that these TiO2-NPs have an even diameter of approximately 5 nm.Moreover,because of their small crystalline sizes and large specific surface areas,most of these as-prepared TiO2-NPs exhibit considerably better absorption and photocatalytic performance with methylene blue than commercial P5 TiO2 does.
