采用两次水热法成功制备了3D石墨烯支撑的Ag 3 PO 4/BiPO 4纳米棒（3D Ag 3 PO 4/BiPO 4 NR/GA）p-n异质结。将Ag 3 PO 4/BiPO 4 NR固定在片状石墨烯纳米片表面形成3D气凝胶结构后，观察到其结构和尺寸的变化。实验结果表明，在模拟太阳光照射下，所制备的3D Ag 3 PO 4/BiPO 4 NR/GA复合光催化剂对RhB的去除率可达96.8%，高于紫外光照射下的67.7%和可见光照射下的91.5%。所制备的光催化剂也表现出比Ag 3 PO 4/BiPO 4 NR更高的光催化活性。除了3D石墨烯结构和p-n异质结的存在之外，由模拟太阳光照射引起的活性氧化物种的数量增加，而不是UV或可见光驱动，也是这种增强的模拟太阳光光催化活性的原因。此外，在H2 O2的辅助下，3D Ag 3 PO 4/BiPO 4 NR/GA光催化剂在连续5次循环后，其光活性可完全恢复，具有良好的稳定性和光催化循环性能。
3D graphene supported p-n heterojunction of Ag3PO4/BiPO4 nanorods (3D Ag3PO4/BiPO4 NR/GA) were successfully prepared by two successive hydrothermal process. Both the changes of structure and size of Ag3PO4/BiPO4 NR were observed after anchoring them on the surface of flake-like graphene nanosheets to form 3D aerogel structures. Experimental results showed that the removal of RhB could reach 96.8% under simulated sunlight irradiation using the prepared 3D Ag3PO4/BiPO4 NR/GA composite as the photocatalyst, higher than that of 67.7% under UV irradiation and 91.5% under visible light irradiation, respectively. The prepared photocatalyst also exhibited much higher photocatalytic activity than Ag3PO4/BiPO4 NR. Besides the 3D graphene structure and the existence of p-n heterojunction, the increased number of active oxidizing species resulted by simulated sunlight irradiation, neither UV nor visible light driving, were also responsible for such enhanced simulated sunlight photocatalytic activity. Moreover, the photoactivity of the used 3D Ag3PO4/BiPO4 NR/GA photocatalyst can be fully restored after five successive cycles with an aid of H2O2, exhibiting a good stability and photocatalytic cycling performance.
