Beschreibung
Zusammenfassung:	The invention relates to a catalyst for catalytic production of perhalogenated ethylene, which at least comprises nitride and/or carbide of VIII group and/or VIB group and/or IIB group metals as catalyst active components, and a preparation method of the catalyst comprises the following steps: (1) preparing a metal oxide precursor; (2) carrying out temperature programming reduction nitridation and/or carbonization; and (3) passivating to obtain the catalyst. 本发明涉及一种用于催化生产全卤代乙烯的催化剂，至少包括以VIII族和/或VIB族和/或IIB族金属的氮化物和/或碳化物为催化剂活性组分，其制备方法包括步骤(1)制备金属氧化物前驱体；步骤(2)程序升温还原氮化和/或碳化；步骤(3)钝化，即制得该催化剂。
