摘要

通过合理控制洗涤程度，采用熔盐路线合成了含有 Li+ 和 Cl- 离子的聚三嗪酰亚胺（PTI/Li + Cl-）。基于 XRD、紫外拉曼、原子力显微镜和 XPS 测量的系统分析证实了彻底洗涤导致的相纯 PTI 框架的表面转变。铀离子吸附实验进一步支持了从三嗪单元 PTI 到七嗪基石墨氮化碳的表面结构转变。对 PTI 材料应用的探索应主要针对无水领域，以获得良好的可重复性。

Surface structural transformation and adsorption performance of Poly(triazine imide)

Poly(triazine imide) synthesized by the molten salt route with incorporation of Li+ and Cl‒ ions (PTI/Li + Cl-) was prepared by rational controlling the washing extent. The surface transformation of the phase-pure PTI framework incurred by thorough washing has been confirmed by a systematic analysis based on XRD, UV Raman, AFM and XPS measurements. Uranyl ion adsorption experiments further support the surface structural transformation from triazine-unit PTI to heptazine-based graphitic carbon nitride. Efforts on the exploration of PTI material application should be mainly directed to the waterless fields to give good repeatability.
