In spite of recent progress in developing hollow micro/nanostructures, the synthesis of three-dimensional adsorbents with high adsorption efficiency and capability on the basis of these structures still remains a great challenge. Herein, we demonstrate a facile hydrothermal strategy to synthesize uniformly dispersed hollow CuWO spheres. The as-prepared CuWO spheres with unique mesoporous structure show favorable selective adsorption for cationic dyes and good recyclability. The adsorption capacity of hollow CuWO towards methylene blue (MB) reaches 59.82 mg g. Furthermore, the hollow CuWO spheres present enhanced photoelectrochemical performance under visible light illumination. This strategy of acquiring specifically functionalized materials from smart design and simple chemical process has opened up wide opportunities on the fabrication of alternative absorbents and photoelectrodes based on CuWO substrate.
尽管最近在开发中空微/纳米结构方面取得了进展，但基于这些结构合成具有高吸附效率和能力的三维吸附剂仍然是一个巨大的挑战。在此，我们展示了一种简便的水热策略，用于合成均匀分散的中空 CuWO 球体。所制备的具有独特介孔结构的 CuWO 球体对阳离子染料表现出良好的选择性吸附和良好的可回收性。中空 CuWO 对亚甲基蓝 (MB) 的吸附容量达到 59.82mg g。此外，中空 CuWO 球体在可见光照射下表现出增强的光电化学性能。这种从智能设计和简单化学过程中获取特定功能化材料的策略为基于 CuWO 基底的替代吸附剂和光电电极的制造开辟了广阔的机会。
