摘要

研究了以α-Fe

、β-Fe

和γ-Fe

为催化剂的类Fenton试剂溶液氧化吸收NO的过程，分析了3种Fe

的晶相结构和表面性质对NO脱除效率的影响机理。脱硝性能测试结果表明：γ-Fe

的活性最好，在H

浓度为1.5 mol/L、催化剂浓度为20 mmol/L、pH值为5以及反应温度为55℃等条件下，γ-Fe

的脱硝率可达87.5%。机理研究表明：3种Fe

催化H

分解湿法脱除NO的反应发生在催化剂表面，反应过程中存在氧化还原循环，H

催化分解的主要产物是·OH。活性差异分析结果表明：Fe

的晶相结构和表面性质对NO的脱除效果具有显著的影响，γ-Fe

的活性最高是由于比表面积大、分散性高和表面的Fe

含量更多，而β-Fe

的活性高于α-Fe

是由于表面的氧空位含量更多。

Abstract

The process of oxidative absorption of NO by Fenton-like reagents using α-Fe

β-Fe

and γ-Fe

as catalysts was studied

and the impact mechanisms of crystal structure and surface property of three Fe

on the NO removal efficiency were also analyzed. It is found that the denitration performance of γ-Fe

is the best and the NO removal efficiency could reach 87.5% with the H

concentration of 1.5 mol/L

catalyst concentration of 20 mmol/L

pH value of 5 and reaction temperature of 55℃. The mechanism investigation indicates that the reactions of H

decomposition catalyzed by three Fe

for NO removal occur on the surface of catalysts

the redox cycle exists in the reaction process and the main product of H

decomposition is ·OH. Activity difference analysis indicates that the influence of crystal structure and surface property of Fe

on the NO removal is obvious. The highest activity of γ-Fe

can be attributed to its large specific surface area

high dispersion and abundant Fe

on the surface and the activity of β-Fe

is higher than α-Fe

due to more oxygen vacancies on the surface.
