我们报道了通过简单的自下而上的方法，使用乙醇铌的水热合成，在三乙醇胺作为结构改性剂的帮助下制备的单分子片：这些分子实体对自身的高动力学稳定性组装允许它们与其他胶体良好混合，并促进它们广泛的电子相互作用，因此从水中的光催化析氢活性比单一组装的复合物增强得多。由于有效的电子转移和电荷分离，用石墨烯和MoS2取代薄片。
We report single molecular sheets of niobate prepared by a simple bottom-up approach using hydrothermal synthesis of niobium ethoxide with the aid of triethanolamine as a structural modifier: the high kinetic stability of these molecular entities against self-assembly allows them to mix well with other colloids and facilitates their extensive electronic interactions and thus photocatalytic hydrogen evolution activity from water is much enhanced over composite of single niobate sheets with graphene and MoS2 due to efficient electron transfer and charge separation.
