Mesoporous g-C₃N₄ nanorods (NRs) are synthesized through the nano-confined thermal condensation of cyanamide in silica nanotubes (NTs) with porous shells. The gas bubbles retained during condensation and the limited cyanamide precursor inside the silica NTs lead to the formation of mesoporous g-C₃N₄. This nano-confined reaction is an alternative method to the traditional templating process for the synthesis of mesoporous materials. The as-prepared mesoporous g-C₃N₄ NRs exhibit remarkably improved photocatalytic activity and high stability in water splitting and degradation of Rhodamine B compared with bulk g-C₃N₄.

纳米管内的受限反应：介孔gC的新方法3ñ4 光触媒

中孔gC ₃ N ₄纳米棒（NRs）是通过氰胺在具有多孔壳的二氧化硅纳米管（NTs）中的纳米约束热缩合而合成的。缩合过程中保留的气泡和二氧化硅NTs内部有限的氰酰胺前体导致形成中孔gC ₃ N ₄。这种纳米限制的反应是合成中孔材料的传统模板工艺的替代方法。与大量gC ₃ N ₄相比，制备的介孔gC ₃ N ₄ NRs在水分解和罗丹明B降解方面显示出显着改善的光催化活性和高稳定性。
