| 摘 要： | 用溶胶-凝胶法合成双钙钛矿氧化物Sr2CaWO6,用半湿法合成Sr2CaWO6和Sr2CaMoO6样品.对制得的Sr2CaWO6和Sr2CaMoO6样品进行X射线衍射(XRD)和扫描电镜(SEM)分析,并测试其光催化分解水制氢和光催化降解酸性红B的活性.考察半湿法合成Sr2CaWO6和Sr2CaMoO6前驱体时草酸铵加入量对样品性能的影响.结果表明,Sr2CaWO6在紫外光的照射下既可以分解水产生氢气,也可以降解酸性红B,且不同方法制得的样品活性相近,而Sr2CaMoO6在紫外光照射下不具有光催化活性.半湿法合成Sr2CaWO6和Sr2CaMoO6时加入一定量的草酸铵可提高样品的纯度和结晶完整性.
