Novel synthetic route to Ce-Cu-W-O microspheres for efficient catalytic oxidation of vinyl chloride emissions[J].

用于氯乙烯废气高效催化氧化的Ce-Cu-W-O微球的新颖合成
通过扫描电子显微镜,X射线能谱和X射线衍射分析,我们解析了Ce-Cu-W-O微球上不同元素组分在水热过程中的生长阶段和物相状态.NH3程序升温脱附分析验证了W物种的添加将提高Ce-Cu氧化物的酸性.H2程序升温还原分析表明,共沉淀方式引入W会降低Ce-Cu氧化物的氧化还原性,而水热一步法制备Ce-Cu-W-O微球的氧化还原性却得到了改善,归因细小晶粒尺寸CuO物种的生成.此外,拉曼光谱和XPS分析表明,HW-CeCuW催化剂具有更多的氧空位,有利于活性氧物种的迁移.因此,Ce-Cu-W-O微球表现出优异的低温氧化活性(250℃时的反应速率为2.01×10-7mol/(gcat·s))和较高的HCl选择性.同时,Ce-Cu-W-O微球经三次循环测试后性能仅略微下降,且在300℃下进行72h的耐久性实验中保持稳定的VC转化率和矿化率,表明其良好的热稳定性.本合成策略可以为高效的CVOC催化氧化的金属氧化物催化剂的设计和合成提供一些新思路.
