The high surface energy of nanomaterials endows them a metastable nature, which greatly limits their application. However, in some cases, the degradation process derived from the poor stability of nanomaterials offers an unconventional approach to design and obtain functional nanomaterials. Herein, based on the poor stability of ZnSe-[DETA]_0.5 hybrid nanobelts, we developed a new strategy to chemically graphitize and functionalize graphene oxide (GO). When ZnSe[DETA]_0.5 hybrid nanobelts encountered a strong acid, they were attacked by H⁺ cations and could release highly reactive Se²⁻ anions into the reaction solution. Like other common reductants (such as N₂H₄·H₂O), these Se²⁻ anions exhibited an excellent ability to restore the structure of GO. The structural restoration of GO was greatly affected by the reaction time, the volume of HCl, and the mass ratio between GO and ZnSe[DETA]_0.5 nanobelts. By carefully controlling the reaction process and the post-processing process, we finally obtained several Se-based reduced GO (RGO) nanocomposites (such as ZnSe/Se-RGO, ZnSe-RGO, and Se-RGO) and various selenide/metal-RGO nanocomposites (such as Ag₂Se-RGO, Cu₂Se-RGO, and Pt-RGO). Although the original structure and composition of ZnSe[DETA]_0.5 nanobelts are destroyed, the procedure presents an unconventional way to chemically graphitize and functionalize GO and thus provides a new material synthesis platform for nanocomposites.

纳米材料的高表面能赋予它们亚稳态的性质，这极大地限制了它们的应用。然而，在某些情况下，源自纳米材料稳定性差的降解过程为设计和获得功能纳米材料提供了一种非常规的方法。在此，基于ZnSe- [DETA] _0.5杂化纳米带的不良稳定性，我们开发了一种新的策略来化学石墨化和功能化氧化石墨烯（GO）。当ZnSe [DETA] _0.5杂合纳米带遇到强酸时，它们会受到H ⁺阳离子的攻击，并会向反应溶液中释放高反应性的Se ^2-阴离子。像其他常见的还原剂（例如N ₂ H ₄ ·H ₂O），这些Se ^2-阴离子显示出极好的恢复GO结构的能力。GO的结构恢复受反应时间，HCl的体积以及GO与ZnSeDETA _0.5纳米带之间的质量比的影响很大。通过仔细控制反应过程和后处理过程，我们最终获得了几种基于硒的还原GO（RGO）纳米复合材料（例如ZnSe / Se-RGO，ZnSe-RGO和Se-RGO）以及各种硒化物/金属- RGO纳米复合材料（例如Ag ₂ Se-RGO，Cu ₂ Se-RGO和Pt-RGO）。虽然ZnSe [DETA] _0.5的原始结构和组成 纳米带被破坏，该程序提供了一种化学方法将GO化学石墨化和功能化的方法，从而为纳米复合材料提供了新的材料合成平台。
