摘要(Abstract)：

为了解不同整体构件钙钛矿催化剂的VOCs催化燃烧特性,以不锈钢316L丝网和堇青石蜂窝陶瓷为基材,通过电泳沉积和浸涂技术在基材表面均匀涂覆γ-Al2O3粘合层,再在涂层表面负载钙钛矿型2.0%(wt)的La0.8Sr0.2MnO3活性组分。SEM表征发现100nm左右的La0.8Sr0.2MnO3颗粒可以均匀、牢固地分散在不锈钢丝网和蜂窝陶瓷表面,经过550℃焙烧后无龟裂现象。超声振荡30min后,活性组分损失率均小于5.0%(wt)。甲苯催化燃烧测试表明,金属丝网型、蜂窝陶瓷型和颗粒型La0.8Sr0.2MnO3催化剂表现出相似的催化性能,但金属丝网具有更好的传质效果和热响应速率,更适合处理高空速、温度和浓度波动较大的有机废气。
