After ball milling for 3 h, the activity of 3%-C3N4/TiO2 is 1.2 times as pure TiO2. The UV activity of C3N4/TiO2 is enhanced via mechanochemical milling, indicating the hybrid structure of C3N4/TiO2 materials. With the increase of ball milling time, the number of photocatalytic active sites is also increased. When the ball milling time is
