Method for preparing monatomic catalyst by using bean hydroponic absorption metal complex

The invention discloses a method for preparing a monatomic catalyst by absorbing a metal complex through hydroponic culture of beans, which comprises the following steps: hydroponically culturing bean seeds by using an aqueous solution containing the metal complex to germinate the bean seeds, and preparing the monatomic catalyst by using the bean sprouts which absorb the metal complex after hydroponic culture. According to the method for preparing the monatomic catalyst, raw materials can be efficiently utilized, acidic heavy metal wastewater is not generated, and the preparation cost of the monatomic catalyst can be further reduced. 本发明公开了利用豆子水培吸收金属配合物制备单原子催化剂的方法，通过使用含有金属配合物的水溶液对豆类种子进行水培使其发芽，利用水培后吸收金属配合物的豆芽制备单原子催化剂。本发明制备单原子催化剂的方法可高效利用原料、不产生酸性重金属废水，可进一步降低单原子催化剂的制备成本。
