Method for preparing iron-based catalyst by taking ferrous sulfate as raw material and iron-based catalyst

The invention discloses a method for preparing an iron-based catalyst by using ferrous sulfate as a raw material, and belongs to the field of catalysts and preparation thereof. The method comprises the following steps: dissolving ferrous sulfate by using deionized water to obtain a ferrous sulfate solution, pouring oxalic acid into the ferrous sulfate solution, stirring, and uniformly mixing to obtain a yellow turbid solution; and carrying out centrifugal separation on the yellow turbid liquid to obtain a yellow precipitate, taking out the yellow precipitate, pouring monosaccharide into the precipitate, uniformly stirring, drying, and roasting to obtain a black solid, thereby obtaining the iron-based catalyst. The method can simply and effectively reduce the toxicity of the sulfur elementto the reaction performance of the catalyst, ensures the reaction performance of the catalyst, and is simple to operate and low in wastewater yield. 本发明公开了一种以硫酸亚铁为原料制备铁基催化剂的方法，属于催化剂及其制备领域，包括：利用去离子水溶解硫酸亚铁得到硫酸亚铁溶液，再将草酸倒入硫酸亚铁溶液中
