四、穆斯堡尔谱学在催化研究中的应用 1.催化剂制备和催化剂特征方面的研究 (1)制备条件对催化活性的影响众所周知,催化剂活性的高低与原料的选择和制备条件密切相关。通常做为催化剂不管是单粗份、多组份或是负载型,其制备条件总是先得到半成品,例如先形成沉淀或先经过浸渍或离子交换,而后再经一定的处理例如煅烧、还原等等,使催化组份达到所要求的状态。而一个高活化状态催化剂的获得,往往决定于在这一系列制备过程中适宜的时间、温度、酸碱度等条件的选
Fourth, the application of Mossbauer spectroscopy in catalytic research 1 catalyst preparation and catalyst characteristics (1) the preparation conditions on the catalytic activity is well known, the level of catalyst activity and raw material selection and preparation conditions are closely related. Usually as a catalyst, whether it is single crude, multi-component or load type, the preparation conditions are always obtained first semi-finished products, such as precipitation or first after impregnation or ion exchange, and then after certain treatment such as calcination, reduction, etc. Etc., to bring the catalytic component to the desired state. The acquisition of a catalyst with a high activation state often depends on the selection of suitable conditions such as time, temperature, pH, etc. during the series of production processes
