The paper reveals synthesis and investigation of thin films based on composite materials BiFeO3/La2NiMnO6 where BiFeO3 is a multiferroic compound and La2NiMnO6 is a double perovskite. Using these materials photoanodes for "green" hydrogen production by photoelectrochemical water splitting were fabricated. The BiFeO3/La2NiMnO6 composites with La2NiMnO6 content of 50 mass% demonstrated the improved photocatalytic properties in comparison with BiFeO3 material and its use as photoanode allowed to increase the efficiency of hydrogen production by water electrolysis. Keywords: green hydrogen, water electrolysis, electrodes, composite materials.
