在常温下，在二氧化钛光催化剂上，NH3在O2存在下进行了光辅助选择性催化还原NO。从不同类型的TiO2光催化SCR反应的结果可以看出，JRC-TiO11表现出了最好的活性。反应活性与二氧化钛的酸中心数量有关，而不依赖于比表面积和晶体直径。金红石和锐钛矿的混合物比相应的任何一种二氧化钛单相催化剂都具有更高的活性。(C)2005 Elsevier B.V.保留所有权利。
Photoassisted selective catalytic reduction (photo-SCR) of NO with NH3 in the presence of O-2 takes place at room temperature over TiO2 photocatalyst. From the results of photo-SCR reaction over various TiO2, we found that JRC-TIO-11 exhibited the best activity. The reaction activity correlated to the amount of acid sites of TiO2, but did not depend on the specific surface area and crystal diameter. The mixture of rutile and anatase shows higher activity than any of the corresponding TiO2 single phase catalyst. (c) 2005 Elsevier B.V. All rights reserved.
