摘要:
以Ta2O5为原料,研究高温固相氮化法合成TaON。考察煅烧时间、煅烧温度及NH3流速对TaON合成的影响,并通过光还原法制备Pt担载的Pt/TaON,利用X线衍射仪(XRD)、场发射扫描电子显微镜(FESEM)、紫外-可见分光光度计(UV-vis)、透射电子显微镜(TEM)和N2吸附-脱附分析仪等测试技术对样品进行表征。结果表明:煅烧温度为900 ℃、NH3流速为100 mL/min时,煅烧3 h获得纯相的TaON具有较高的比表面(10.9 m2/g)。担载Pt(3%)纳米颗粒后,2 h内对于罗丹明-B的降解达到60.8%。
Abstract:
TaON was prepared by Ta2O5 using solid state nitridation at high temperature.The effects of reaction conditions, such as calcination time,calcination temperature and ammonia gas flow rate, were investigated.Pt/TaON was obtained by a photo reduction method.The prepared photocatalysts were characterized by X-ray diffraction(XRD),field emission scanning electron microscopy(FESEM),ultraviolet-visible spectrophotometer(UV-vis),transmission electron microscopy(TEM), and N2 adsorption-desorption analysis.Results showed that pure TaON with large specific surface of 10.9 m2/g could be synthesized within 3 h when the calcination temperature was 900 ℃ and the ammonia gas flow rate was 100 mL/min.The degradation of Rhodamine-B on Pt/TaON reached 60.8% within 2 h.
