以10种不同载体为载体，制备了Fe_2O_3催化剂，并进行了H_2还原NO的研究。在载体氧化物中，SiO2上的Fe_2O_3是最有效的催化剂，SnO_2上的Fe_2O_3活性最低。用红外光谱法研究了NO在负载型Fe_2O_2上的表面状态和吸附状态。和穆斯堡尔谱。i.r.的强度在1810和1735 cm-1的还原铁位上的吸附NO的频带进行了讨论与催化活性。
Catalytic reduction of NO with H2 has been carried out over Fe2O3 dispersed on ten kinds of supports. Among the carrier oxides, Fe2O3 on SiO2 was the most effective catalyst and Fe2O3 on SnO2 was least active. The surface states and adsorption states of NO on supported Fe2O2 were studied by means of i.r. and Mossbauer spectroscopies. The intensities of the i.r. bands at 1810 and 1735 cm-1 of the adsorbed NO on reduced iron sites are discussed in connection with the catalytic activity.
