Preparation method of boron nitride-based monatomic catalyst for selectively generating < 1 > O2

The invention discloses a preparation method of a catalyst, and particularly relates to a universal preparation method of a boron nitride-based monatomic catalyst capable of realizing selective generation of < 1 > O2. The boron nitride loaded metal monatomic catalyst is constructed on the basis of vacancy regulation and control and metal anchoring strategies of boron nitride. The method has the advantages that the strategy is generally suitable for preparation of different metal monoatoms including cobalt, iron, copper, nickel and manganese, the prepared catalyst can achieve efficient generation of < 1 > O2 in a Fenton-like system, and a new strategy is provided for preparation of the < 1 > O2 regulation and control generation catalyst. 本发明公开了一种催化剂的制备方法，具体是指一种可实现1O2选择性生成的氮化硼基单原子催化剂的普适性制备方法。本发明是基于氮化硼的空位调控与金属锚定策略，构筑了氮化硼负载金属单原子催化剂。本发明的优点是：这一策略普适于不同金属单原子的制备，包括钴、铁、铜、镍、锰，并且所制备的催化剂均可在类芬顿体系中实现1O2的高效生成，为1O2的调控生成催化剂的制备提供了新策略。
