Abstract SnO/Graphitic-C3N4 (g-C3N4) photocatalysts were prepared by a simple solid phase grinding-assisted ultrasonic synthesis technology. Results showed that SnO/g-C3N4 composites with moderate g-C3N4 exhibit nanosheet morphology. An intimate interface boundary exists between the g-C3N4 and SnO phases in the composites. The composites possess excellent photocatalytic activity. SnO/g-C3N4 exhibits optimum photocatalytic property (7.66%) and highest photoactivity, which could degrade 98% of methyl orange under visible-light irradiation within 80 min.

通过研磨辅助超声路线合成SnO/gC 3 N 4 可见光驱动的光催化剂

摘要 采用简单的固相研磨辅助超声合成技术制备了SnO/Graphitic-C3N4 (g-C3N4)光催化剂。结果表明，具有中等 g-C3N4 的 SnO/g-C3N4 复合材料表现出纳米片形貌。复合材料中 g-C3N4 和 SnO 相之间存在紧密的界面边界。该复合材料具有优异的光催化活性。SnO/g-C3N4 表现出最佳的光催化性能（7.66%）和最高的光活性，在可见光照射下 80 分钟内可降解 98% 的甲基橙。
