| 摘 要： | 对光催化转化氮氧化物的研究进展进行了综述.首先介绍了氮氧化物的危害及传统处理方法的缺点以及光催化反应的机理;随后着重介绍了以TiO2为催化剂对NOx去除的研究进展,并对其他用于分解氮氧化物新型光催化进行了介绍;最后对应用前景作出展望.光催化转化氮氧化物的研究分为光催化氧化和光催化还原2种,反应器则主要为固定床反应器和流化床反应器.N原子的搀杂、氧空穴的产生以及表面负载Pt均能有效地利用可见光,炭(AC)、沸石、氧化钙、ZrO2、高岭土等载体也可明显地提高光催化转化氮氧化物的效率.此外,植入过渡金属离子沸石,也可有效地转化氮氧化物. |

| Abstract: | Research advances of photocatalytic conversion of NOx were reviewed.The hazards of NOx,and drawbacks of traditional remove methods,photocatlysis mechanism and progress in NOx removal by TiO2 and other new photocatalysts were introduced.Future development of this technology was presented.There were mainly two different kinds of photocatlytic reaction forms,which were photocatlytic oxidation and photocatlytic deoxidization with two reactors(fixed bed reactor and fluidized bed reactor).Doping with N atoms,O vacancy and loading Pt atom at the surface could make full use of visible light during conversion of NOx.Besides,new kinds of vector,such as activated carbon,zeolite,CaO,ZrO2 and kaolin,enhanced the photocatalytic efficiency notably.Zeolite incorporated with transition metals ions could also improve the conversion of NOx. |
