A new carbon quantum dots/porous InVO 4 (CQDs/p‐InVO 4 ) microsphere composite was synthesized by a facile reflux method. The relationship of structure and property of CQDs/p‐InVO 4 was studied in detail. The results show that the as‐prepared composite samples maintain the porous structure of the p‐InVO 4 microspheres, while CQDs are uniformly loaded on the surface of the p‐InVO 4 microspheres with an intimate interface. With this unique structure, the as‐obtained samples exhibit enhanced photocatalytic degradation ability towards Rhodamine B (RhB) under visible‐light irradiation. The synergistic effect of more active sites, increased visible‐light absorption, and high separation efficiency of photogenerated electron–hole pairs is believed to be the reason for the enhanced photocatalytic activity.
