Abstract In this paper, we utilize a two-step solvothermal associated with in-situ ultrasonic precipitation method to construct novel AgCl/g-C3N4 heterostructure nanotube. Thereafter, the structure and morphology of the hybrid was testified by XRD and FE-SEM, indicating that the hybrid was composed of hexagonal phase g-C3N4 and cubic phase AgCl. Furthermore, the AgCl nanoparticles with the average size of 20 nm were completely dispersed on the surface and nozzle of the g-C3N4 nanotube with the average diameter of 100 nm and the average length of 800 nm. Then the decontamination performance of AgCl/g-C3N4 composite was investigated, showing that the AgCl (20%wt)/g-C3N4 composite has higher photocatalytic effect on Rhodamine B (RhB) solution than pure g-C3N4, which has the higher 92% total removal rate of RhB and the larger K value of 0.02827 min−1. The improved photocatalytic performance can be ascribed to the efficient separation and transfer of photo-generated electron-hole at the hybrid interface via a Z-scheme mechanism.

新型 AgCl/g-C3N4 异质结构纳米管：超声波合成、表征和光催化活性

摘要 在本文中，我们利用与原位超声沉淀法相关的两步溶剂热法构建了新型 AgCl/g-C3N4 异质结构纳米管。此后，通过XRD和FE-SEM验证了杂化物的结构和形貌，表明杂化物由六方相g-C3N4和立方相AgCl组成。此外，平均粒径为20 nm的AgCl纳米颗粒完全分散在平均直径为100 nm、平均长度为800 nm的g-C3N4纳米管的表面和喷嘴上。然后考察了 AgCl/g-C3N4 复合物的去污性能,结果表明 AgCl(20%wt)/g-C3N4 复合物对罗丹明 B(RhB)溶液的光催化作用高于纯 g-C3N4,后者具有更高的 92 RhB 的总去除率百分比和较大的 K 值 0.02827 min-1。
