SrCoO_x的制备方法及光催化活性研究

Study on Preparation and Photocatalytic Activity of SrCoO_x

用XRD、TEM等分析技术对样品进行表征,并且催化剂对碱性藏花红染料的降解实验研究了制备方法对钙钛矿型氧化物SrCoOx及其光催化活性的影响,结果表明,用柠檬酸络合法制备的光催化活性比研磨法好。在含SrCoOx催化剂悬浮液中进行碱性藏花红染料光催化降解实验,结果表明:SrCoOx粉体具有较好的催化性,阳光照射4 h,可将碱性藏花红基本分解完全。

The sample was characterized with the analysis technologies of XRD,TEM and so on. The effect of preparation method on SrCoOx and photocatalytic activity was studied by the experiment of safranine dye degeneration.The results showed that the photochemical catalysis activity was better using citric acid than grinding method. In contains in the SrCoOx catalyst suspending liquid to carry on the safranine dye photochemical catalysis degeneration experiment,the result indicated that SrCoOx powder body had good catalysis,the sunlight shining 4 h,the safranine may be completely decomposed.
