摘要
以农业废弃物花生壳衍生少层石墨烯(PS-FLG)为载体,采用水热法制备负载型催化剂,对其NH3-SCR脱硝性能进行了测试。通过XRD,FTIR,SEM等测试手段初步探明了活性组分Ce在A位进行掺杂增强催化活性的内在机制。结果表明,在250℃-350℃时催化剂活性都能达到90%以上并保持稳定,且催化剂5%La0.5Ce0.5MnO3/PS-FLG表现出最好的低温催化活性。金属氧化物更均匀地分散在少层石墨烯表面,使其表现出更好的脱硝活性。
The catalysts were prepared by the hydrothermal method using agricultural waste biomass peanut shell-derived few-layer graphene (PS-FLG) as the support. The intrinsic mechanism of Ce-doping at the A site in active components to enhance the catalytic activity has been explored by using characterization methods of XRD, FTIR, SEM and the denitration performance test of NH3-SCR. The results showed that the activities of the catalyst were over 90% and kept stable at 250℃-350℃, 5% La0.5Ce0.5MnO3/PS-FLG has the best denitration performance, and the metal oxide is more evenly dispersed on the surface of the few-layer graphene which makes it show better denitration activity.
