摘要
采用炭化法制备三维石墨烯(3DG)载体,采用共沉淀法制备了LaCuOδ/3DG,LaCu0.5Mn0.5Oδ/3DG和LaCu0.5MO0.5Oδ/3DG催化剂。利用XRD、SEM和TEM对催化剂和载体进行了表征。脱硝性能测试结果显示,催化活性的顺序为LaCu0.5Mo0.5Oδ/3DG>LaCu0.5Mn0.5Oδ/3DG>LaCuOδ/3DG,表明三元活性组分比二元活性组分具有更好的催化活性,引入Mo元素比Mn元素更有助于提高LaCuOδ/3DG双金属氧化物的催化性能。
The three dimensional graphene (3DG) support and LaCuOδ/3DG、LaCu0.5Mn0.5Oδ/3DG and LaCu0.5MO0.5Oδ/3DG catalysts were prepared by carbonization and coprecipitation. The support and catalysts were characterized by XRD, SEM and TEM. The results of denitrification test showed that the order of catalytic activity was LaCuOδ/3DG < LaCu0.5Mn0.5Oδ/3DG< LaCu0.5Mo0.5Oδ/3DG. The results indicated that the active ternary component had better catalytic activity than the active binary component, and the introduction of Mo element was more helpful to improve the catalytic performance of LaCuOδ/3DG bimetallic oxygenate.
