Many recent advances in constructing green metal-free materials have opened new possibilities in catalysis. To explore and enhance the photocatalytic performance of g-C₃N₄ quantum dots (CN QDs), the metal-free materials of CN QDs embedded in the h-BN was successfully synthesized by calcination the mixture of melamine and h-BN. The studies proved the CNBN has appeared red-shift due to the quantum size effect and 2D h-BN. The CN QDs were embedded into the h-BN could not only facilitate the separation and transfer, but also the h-BN terminated with OH groups could act as active sites, thus enhanced the photocatalytic performance. Moreover, this work may pave the way for the application of CN QDs and fabricate 2D h-BN composites for green metal-free materials in another field.

在构造不含金属的绿色材料方面的许多最新进展为催化开辟了新的可能性。为了探索和增强gC ₃ N ₄量子点（CN QDs）的光催化性能，通过煅烧三聚氰胺和h-BN的混合物成功地合成了嵌入h-BN中的CN QDs的无金属材料。研究证明，由于量子尺寸效应和2D h-BN，CNBN出现了红移。将CN QD嵌入h-BN中不仅可以促进分离和转移，还可以将h-BN终止于OH基团可以作为活性位点，从而增强了光催化性能。而且，这项工作可以为CN QD的应用铺平道路，并为另一个领域的绿色无金属材料制造2D h-BN复合材料铺平道路。
