定制的纳米结构提供了一种新的方式来促进电子-空穴分离，并提供额外的机会来产生独特的光催化剂，这些光催化剂表现出新颖的光吸收，热力学和动力学特性。报道了一种简单而有效的合成多种g-C3 N4定制纳米结构的方法。本文中，NH3和H2 O2被用作可控的化学剪刀，以将块状g-C3 N4定制为各种各样的g-C3 N4纳米结构，其包括剥离的多孔、量子点、纳米微粒和纳米纺锤体。在λ> 420 nm波长下，定制的g-C3 N4显示出比本体g-C3 N4高3.0倍（纯水）和4.1倍（饱和KCl溶液）的H-2释放的光反应性。我们相信这一策略为X掺杂（X = N，S，P和O）碳材料的结构调整以及它们在催化，有机合成，纳米医学和能量存储方面的探索提供了新的机会。
Tailored nanostructures offer a new way to facilitate electron-hole separation and offer additional opportunities to generate unique photocatalysts that demonstrate novel light absorption, thermodynamic and kinetic properties. A simple and efficient approach to the synthesis of a large variety of g-C3N4 tailored nanostructures is reported. Herein, NH3 and H2O2 were used as controllable chemical scissors to tailor bulk g-C3N4 to a large variety of g-C3N4 nanostructures, which include exfoliated porous, quantum dot, nanomites and nanospindles. The tailored g-C3N4 shows a photoreactivity of H-2 evolution 3.0 (pure water) and 4.1 (saturated KCl solution) times higher than bulk g-C3N4 under lambda > 420 nm. We believe this strategy affords new opportunities for structural tuning of X-doped (X = N, S, P, and O) carbon materials, as well as their exploration in catalysis, organic synthesis, nanomedicine and energy storage.
