In this work, defective BiPO 4 with surface phase junction (BPJ) was synthesised using a facile ball‐milling method. The phase composition of BPJ was found to include monazite monoclinic BiPO 4 and monoclinic BiPO 4 . Surface defects on BPJ could be controlled by changing ball‐milling conditions. The optimal sample exhibited significantly enhanced photocatalytic performance compared with BiPO 4 and BPJ under ultraviolet light irradiation. The enhancement of photocatalytic performance was due to the synergistic effect of the surface phase junction and surface defects, which significantly improved the separation and transfer efficiency of photogenerated charges.
