Energy transfer in self-assembled ionic liquids (ILs) and iron oxyhydroxide nanocrystals and the controlled surface chemistry of functionalized nanomaterials for photocatalytic applications are reported. Self-assembled ILs play the role of multifunctional materials in terms of constructing a well-designed nanostructure, controlling the surface chemistry, and triggering the energy transfer of functionalized materials. IL-functionalized beta-FeOOH nanorods show approximately 10-fold higher performances than those of commercial materials due to the synergistic effect of well-defined nanomaterials in diffusion-controlled reactions, specific interactions with target pollutants, and energy transfers in hybrid materials. In particular, the energy transfer in C(4)MimCl-functionalized beta-FeOOH nanorods enhances photocatalytic activity due to the generation of Fe(2+). The strategy described herein provides new insight into the rational design of functionalized inorganic nanomaterials for applications in emerging technologies.
报道了自组装离子液体（ILs）和铁氧氢氧化物纳米晶体中的能量转移，以及用于光催化应用的功能化纳米材料的可控表面化学。自组装的 IL 在构建精心设计的纳米结构、控制表面化学和触发功能材料的能量转移方面发挥了多功能材料的作用。由于在扩散控制反应中具有良好定义的纳米材料的协同效应、与目标污染物的特定相互作用以及混合材料中的能量转移，IL 功能化的β-FeOOH 纳米棒的性能比商业材料高出约 10 倍。特别是，由于生成了 Fe(2+)，C(4)MimCl 功能化的β-FeOOH 纳米棒中的能量转移增强了光催化活性。本文所述的策略为合理设计用于新兴技术的功能化无机纳米材料提供了新的思路。
