摘　　要：为了提高光催化室内空气净化效率,将催化技术与低温等离子体(NTP)技术相结合,通过实验分析了NTP协同作用下室内污染物甲醛的光催化去除效果.结果表明,NTP协同光催化技术可以大幅提高污染物去除效率,且污染物去除率随着等离子体激发电压的增加而增大,在最大激发电压下,污染物去除率达到最大值.因此,将光催化技术与NTP技术相结合是光催化技术实际应用的一个研究方向.In order to enhance the photocatalytic indoor air purifying efficiency,the photocatalytic technology was combined with non-thermal plasma to improve the removal of indoor air contaminants.The experimental results show that the removal rate of formaldehyde is improved sharply by plasma and photocatalysis.The removal rate of formaldehyde is increased with the increasing of excited voltage for plasma and the removal of contaminants has the maximal value under the optimal excited voltage in this paper.So the combination of photocatalysis with plasma is an applying direction of photocatalytic technology for air purification.
