The Ni foil or fluorine‐doped SnO2 transparent conductive glass substrates modified by BiFeO 3 film with a different atomic ratio of Bi to Fe were prepared by the method of spin coating‐calcination at a different temperature. Coupling photo‐catalysis with electro‐catalysis, resourceful treatment of salty organic wastewater containing methyl orange and cadmium ion was proposed and experimentally achieved. Under visible light irradiation, the highest H 2 ‐production rate (5.46 ml/h cm 2 ), degradation efficiency of methyl orange (51.6%), and the recovery precipitation weight of cadmium hydroxide (0.1846 g) were obtained with Ni foil modified by BiFeO 3 (Bi:Fe = 1.10:1.00) film at 550°C of calcination. X‐ray diffraction, ultraviolet–visible diffuse reflectance spectroscopy, scanning electron microscopy, and the resourceful treatment test of salty organic wastewater were used to characterise the catalyst film.
