Two-dimensional molybdate/molybdenum oxide based composite material as well as preparation method and application thereof

The invention provides a two-dimensional molybdate/molybdenum oxide-based composite material as well as a preparation method and application thereof. The method comprises the following specific steps: uniformly mixing ammonium molybdate, lactic acid, metal chlorate and water according to a certain ratio, and crystallizing the mixture in a drying oven at 180 DEG C for 24 hours to obtain a black solution; and cooling the black solution, centrifuging, washing, and finally roasting the obtained solid at 400 DEG C for 3 hours to obtain the two-dimensional molybdate/molybdenum oxide-based composite material. According to the preparation method, a simple one-step hydrothermal method is adopted, the ratio of raw materials is adjusted, then roasting is performed, metal molybdate particles are successfully and uniformly loaded on the two-dimensional molybdenum oxide nanosheets, the molybdate/molybdenum oxide-based composite material is obtained, and the method has the advantages of being simple in equipment, convenient
