The invention discloses a method for preparing chloroethylene carbonate. The method comprises a step of synthesizing chloroethylene carbonate through ethylene carbonate and a chlorination agent in an illumination condition by use of a transition metal nanoparticle photosensitizer. The chloroethylene carbonate comprises monochloroethylene carbonate and dichloroethylene carbonate. The adopted catalyst is a transition metal nanoparticle photosensitizer. The illumination condition is ultraviolet illumination or illumination of visible light including sunlight and ordinary lighting. The chlorination agent comprises chlorine, sulfuryl chloride, thionyl chloride, triphosgene, etc. The preparation method provided by the invention is different from the thermal catalysis and ultraviolet catalysis of traditional technology, the reaction conditions are milder, the reaction is fast, and the production efficiency is high; the synthesis equipment can be made of common glass material, and a reactor of special material such a
