Two-dimensional atomically thin boron nitride (BN) nanosheets possess many distinctive properties but their applications are still being hindered by the technical difficulties in their synthesis methods, due to the strong lip-lip interactions between their basal planes. In this paper, we reported a facile and scalable bottom-up approach to synthsizing atomically thin BN nanosheets in a molten salt medium. As-prepared BN nanosheets can be used as an effective co-catalyst to improve the catalytic performance of carbon nitride photocatalyst, owing to the interfacial effect induced by their addition. In the case of photodegradation of rhodamine B, for example, the photodegradation rate of carbon nitride could be approximately doubled when 5 wt% as-prepared BN nanosheets were added.
二维原子级薄的氮化硼（BN）纳米片具有许多独特的性质，但由于其基面之间的强范德华相互作用，其合成方法的技术困难仍然阻碍了它们的应用。在本文中，我们报道了一种在熔融盐介质中合成原子级薄 BN 纳米片的简便、可扩展的自上而下的方法。所制备的 BN 纳米片可以作为一种有效的共催化剂，提高氮化碳光催化剂的催化性能，这归因于它们的添加所引起的界面效应。例如，在罗丹明 B 的光降解中，当添加 5wt%的所制备的 BN 纳米片时，氮化碳的光降解速率可以提高近两倍。
