The invention discloses a houghite photocatalyst based on visible light response and a preparation method thereof, belonging to the technical field of preparation of photocatalysts. A series of houghite photocatalysts with response under visible light are synthesized by adopting a nucleation/crystallization separation method. By adjusting and controlling the composition of metal and interlaminar guest ions, a series of photocatalysts with excellent performance and full spectrum absorption under visible light can be obtained. The series of catalysts have very high absorption, can make full use of visible light part of sunlight, have high dye photocatalysis performance, can be applied to photocatalytic degradation of environmental pollutants, and have photocatalytic performance greatly superior to that of the conventional P25TiO2 photocatalyst. The photocatalyst produced by adopting the preparation method has low cost and simple process, is easy and convenient to operate, and is easy for mass production.
