Method for electrolyzing water by using external magnetic field
The invention provides a method for electrolyzing water by using an external magnetic field. The method comprises the following steps: (1) applying a perovskite material serving as a water electrolysis catalyst to an electrode in an electrolytic bath; (2) applying a magnet to the periphery of the electrolytic bath so as to promote the efficiency of electrolyzing water; the chemical formula of the perovskite material is SrFe (1-x) CoxO3, wherein x is more than 0.1 and less than 0.9. The perovskite material SrFe < 1-x > Co < x > O < 3 > provided by the invention is a material with ferromagnetism and metallicity at a temperature close to room temperature, and the magnetism and Curie temperature of the perovskite material can be changed in a range of 100-350K by adjusting a Fe/Co doping ratio. After the perovskite material is applied to electrolyzed water, the perovskite material has excellent electrocatalytic activity. In addition, when the magnet is close to the electrolytic bath, the electro-catalytic reaction efficiency is remarkably improved.
本发明提供一种利用外磁场进行电解水的方法，其包括以下步骤：(1)向电解槽中的电极上施加作为电解水催化剂的钙钛矿材料；(2)向所述电解槽周围施加磁体，以促进电解水的效率；所述钙钛矿材料的化学式为SrFe1‑xCoxO3，其中0.1＜x＜0.9。本发明的钙钛矿材料SrFe1‑xCoxO3是一种在室温附近具有铁磁性和金属性的材料，其磁性和居里温度可通过调节Fe/Co掺杂比例在100‑350K范围变动。本发明的钙钛矿材料应用于电解水后，具有优异的电催化活性。此外，在当磁铁靠近电解槽时，电催化反应效率显著提升。
