在以四氧化三钴为载体的金催化剂上,进行了一氧化氮还原反应的研究,催化剂采用共沉淀法制备。在固定床反应器中进行了催化剂活性与温度,活性随时间的变化及金担载量。硫、铅中毒实验。在5wt%金催化剂上进行了还原反应的表现动力学研究,得到了还原反应动力学模型。提出了金催化剂反应机理—金超细微粒子与载体作用,自身d轨道电子向s轨道跃迁。从而形成与铂相似的电子层构造的假说。
In the cobalt oxide as the carrier of the gold catalyst, a study of the reduction of nitrogen monoxide, the catalyst prepared by coprecipitation. Catalyst activity and temperature, activity over time, and gold loading were carried out in a fixed bed reactor. Sulfur, lead poisoning experiment. The kinetics of the reduction reaction was studied on a 5wt% gold catalyst. The kinetic model of the reduction reaction was obtained. The gold catalyst reaction mechanism was proposed - the effect of the ultrafine particles of Au on the carrier and the transition of the d orbital electrons to the s orbital. Thus forming a hypothesis that the structure of the electron layer is similar to that of platinum.
