摘　　要：低温等离子体技术在化学生产中的用途越来越广泛 ,它在催化剂领域的应用主要表现在以下几个方面 :超细颗粒催化剂合成 ,催化剂再生 ,催化剂表面处理 ,活性组分沉淀到基体以及低温等离子体系统中添加催化剂。经过低温等离子体制备或处理过的催化剂 ,其催化活性有显著提高。在等离子体反应系统中加入适当的催化剂 ,可以降低等离子体击穿电压 ,减少能量消耗 。Low temperature plasma has been extensively investigated for catalyst preparation, including plasma chemical synthesis of ultra-fine particle catalysts, plasma regeneration or plasma treatment of catalysts, plasma-assisted deposition of catalytically active compounds on carriers and combination of plasma and catalyst in reaction system. The plasma-prepared catalysts or catalysts modified by plasma exhibit higher catalytic reactivity. Combined with catalyst, plasma could be generated easily at lower voltage,which decreases the energy consumption and promotes the reactions.
