摘要：

采用介质阻挡放电（DBD）低温N₂、O₂等离子体技术对黏胶基活性炭纤维（V-ACF）进行表面改性，运用BET、SEM、NH₃-TPD和 FT-IR对催化剂进行表征，并对催化剂低温选择性催化还原（SCR）NO性能进行了研究。结果表明，N₂、O₂等离子体最佳改性时间分别为5 min与10 min，最佳反应温度为100 ℃，低温等离子体改性能明显提高ACF上NO转化率，且N₂等离子体改性ACF催化效率高于O₂等离子体改性ACF。

Abstract:

Viscose-activated carbon fiber（V-ACF）modified by low-temperature N₂ and O₂ plasma with dielectric barrier discharge（DBD）was studied for low-temperature selective catalytic reduction（SCR）of NO. Structure of the plasma modified V-ACF was characterized by BET，SEM，NH₃-TPD and FT-IR. Experimental results showed that the optimal surface modification time was 5 and 10 minutes for N₂and O₂plasma，respectively. The optimal reaction temperature was 100℃. Surface modification of V-ACF by low-temperature plasma technology could greatly improve the NO removal rate. V-ACF modified by N₂ plasma showed higher NO removal rate than that modified by O₂ plasma.
