The purpose of this project is to construct highly ordered three-dimensional (3D) heterostructures at nano-scale with the modification of noble metallic nanoparticles, Ln nanoparticles or narrow gap semiconductor nanoparticles that can further extend light absorption range. The structure-activity relationship between the nanoparticle-modified highly ordered 3D heterostructures and the photoelectrochemical (PEC) water splitting performance is the main object to investigate how to improve the photoelectric conversion efficiency. The highly ordered 3D nanostructures shall be fabricated using template-based method, including anodic alumina oxide (AAO) nano-porous and polystyrene (PS) sphere templates. Then, the modification of functional nanoparticles will be mainly carried out by hydrothermal method in order to realize the 3D heterostructured photoelectrodes with the ability of responding to visible and infrared light. Through the optimization of the 3D heterostructured photoelectrodes in terms of nano-morphology, semiconductor matrixes, energy level structures, and composition, the PEC water splitting performance will be investigated in details to gain systematical understandings of the structure-activity relationship.

本研究的目的是通过对贵金属纳米颗粒、稀土纳米颗粒或窄禁带半导体纳米颗粒的修饰，在纳米尺度上构建高度有序的三维异质结构，以进一步扩展光吸收范围。纳米粒子修饰的高度有序三维异质结构与光电化学（PEC）水分解性能之间的构效关系是研究如何提高光电转换效率的主要目标。高度有序的三维纳米结构的制备应采用基于模板的方法，包括阳极氧化铝（AAO）纳米多孔和聚苯乙烯（PS）球模板。然后，将主要通过水热法对功能纳米粒子进行改性，以实现具有可见光和红外光响应能力的三维异质结构光电极。通过优化三维异质结构光电极的纳米形貌、半导体基质、能级结构和组成，详细研究PEC水裂解性能，以获得系统的结构-活性关系。
