The invention discloses highly self-cleaning hydrophilic glass. The structure of the glass comprises a common glass layer, wherein a highly self-cleaning hydrophilic layer is pasted on the common glass layer. A preparation method of the highly self-cleaning hydrophilic glass comprises the following steps of: A, preparation of titanium tetrachloride solution; B, hydrolysis: dropping the titanium tetrachloride solution obtained in the step A into ammonia solution to obtain a titanium dioxide deposit; C, complexation: pulping the filter cake obtained in the step B, and adding tartaric acid or propane diacid into the pulp to obtain colorless transparent solution; D, heating, refluxing and hydrolysis: heating, refluxing and hydrolyzing the colorless transparent solution to obtain a nano titanium dioxide colorless transparent hydrosol; and E, preparation of the highly self-cleaning hydrophilic layer: uniformly spraying the colorless transparent hydrosol obtained in the step D to the surfaceof the common glass, and naturally drying the glass at room temperature. The highly self-cleaning hydrophilic glass can ensure that organic wastes on the surface of the glass are automatically decomposed into harmless gases under an illumination condition to achieve highly self-cleaning of a glass surface layer; and simultaneously, the highly self-cleaning hydrophilic glass has high hydrophilicity and stability.
