摘要:
为解决介质阻挡放电等离子体催化氨合成效率低下问题 ,采用焙烧法对 MgO表面反应位点进行调控 , 制备出具有高活性的MgO催化剂 ;通过 XRD、XPS、BET、CO2-TPD技术对 MgO理化性质进行表征 ,评估等离子体 放电特性和催化氨合成性能 ,并结合光学发射光谱和原位漫反射红外光谱阐释介质阻挡放电等离子体催化氨合成 的机理 。结果表明:填充 MgO提升氨合成性能 ,主要归因于放电特性的改变:填充 MgO可增强 E/N值 ,进而提升 电子能量 ,有利于氮气和氢气碰撞解离;MgO催化氨合成性能受焙烧温度影响 ,主要归因于反应位点的改变 :改变焙 烧温度会引起表面吸附氧、碱性位点、比表面积变化 ,从而显著影响催化性能;500℃焙烧 MgO样品(MgO-500)催化 性能最佳 ,氨气产量为 7143ppm,能量效率为 0.65g/(kW·h) 。MgO-500表面吸附氧减少、碱性位点最多、比表面 积最大 ,有利于碰撞解离的物种在其表面吸附 ,进而促进 E-R和 L-H反应 ,从而提升氨合成性能 。该研究可为设计 和开发高性能的氨合成催化剂提供理论依据和技术支持。
