The invention provides controllable synthesis of a carbon nitride-bismuth tungstate compound nano-material. The method comprises the following steps: firstly, combining carbon nitride into a bismuth tungstate material by adopting a one-step hydrothermal synthesis method; and then, further combining bismuth tungstate with the carbon nitride-bismuth tungstate compound material by a high-energy ball milling method. The compound nano-material has a sheet structure and is formed by interlacing ultrathin nano-plates having thickness of 18-24nm, the specific surface area of the material is 240-280m /g, the pore volume is 0.24-0.30cm /g, and the performance is very excellent. Furthermore, the compound nano-material has the advantages of simple process, low cost, short cycle, environment friendliness and the like, is applicable to industrial large-scale production, and has excellent photocatalytic activity when being applied to photocatalytic reactions. 本发明提供了种氮化碳-钨酸铋复合纳米材料的可控合成，本发明方法首先在采取步水热合成的方法将氮化碳复合进钨酸铋材料中，随后通过高能球
