快速合成taon及其催化性能
DOI: 10.3969/j.issn.1671-7627.2015.06.009, PP. 44-48
Keywords: taon,降解,可见光,光催化活性
Abstract:
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100ml/min时,煅烧3h获得纯相的taon具有较高的比表面(10.9m2/g)。担载pt(3%)纳米颗粒后,2h内对于罗丹明-b的降解达到60.8%。
