The invention relates to a visible light catalyst for degrading dye in water, a preparation method and application thereof. The visible light catalyst takes lamellar graphite-phase nitrogen carbide as a main body, iron-molybdenum oxide is loaded on the lamellar graphite-phase nitrogen carbide, and the mass fraction of the iron-molybdenum oxide is 10-40% based on the mass of the graphite-phase nitrogen carbide. The preparation method comprises the steps of preparing lamellar graphite-phase nitrogen carbide, and doping the graphite-phase nitrogen carbide with metal oxide-iron-molybdenum oxide. The preparation method overcomes the defects of complex preparation process, long degradation time and the like in the prior art, has simple preparation method, simple and convenient degradation operation, high degradation efficiency, short degradation time and low cost, and can prepare the photocatalyst which has visible light responsiveness and can degrade the dye in the wastewater. |
