通過模板輔助製造低成本工藝的無貴金屬組成的三維氧化銅/二氧化鈦納米棒陣列混和異質結構並應用於染料降解的類光芬頓催化劑。通過電沉積法將氧化銅奈柱沉積在陽極氧化鋁模板內，並在不同溫度下退火，然後通過電子槍蒸發進行二氧化鈦薄膜沉積。在不同溫度下對氧化銅/二氧化鈦異質結構進行退火處理後，p型氧化銅和n型二氧化鈦形成p-n異質結。通過拉曼分析證實了氧化銅納米棒的隕石相和二氧化鈦的銳鈦礦相，而XRD分析證實了氧化銅和二氧化鈦的結晶度。對於氧化銅/二氧化鈦異質結構，分別通過EDS映射和EELS分佈來分析元素和組成的分佈。在加入雙氧水後，500瓦的汞氙弧光燈照射下的氧化銅/二氧化鈦混合結構比氧化銅納米棒更有效的降解羅丹明B。本研究證明了氧化銅納米棒長度對氧化銅納米棒光降解性能以及氧化銅/二氧化鈦異質結構的影響。本文還闡述了光芬頓催化劑在染料光降解中的作用機理和作用。優化的氧化銅/二氧化鈦納米棒陣列結構表現出迄今為止最高的光降解活性。具有高縱橫比，混合氧化銅/二氧化鈦納米棒陣列可以作為PEC水分解的優異光催化劑。

Three-dimensional (3D) CuO/TiO2 hybrid nanorods (NRs) arrays with noble-metal-free composition, fabricated by template-assisted low-cost processes, were used as a photo-Fenton-like catalyst for dye degradation. CuO NRs were deposited inside an AAO template by electrodeposition method and annealed at various temperatures, followed by TiO2 thin film deposition through E-gun evaporation. After annealing treatment of CuO/TiO2 heterostructure at different temperatures, p-type CuO and n-type TiO2 formed the p-n heterojunction. The tenorite phase of CuO NRs and anatase phase of TiO2 were confirmed by Raman analysis, whereas crystallinity of CuO and TiO2 was proved by XRD analysis. For CuO/TiO2 heterostructure, the elemental distribution and composition were analyzed by EDS mapping and EELS profile, respectively. In the presence of H2O2, CuO/TiO2 hybrid structure performed more efficiently than CuO NRs for Rhodamine B degradation under the irradiation of 500 W Mercury-Xenon arc lamp. This study demonstrated the effect of length of CuO NRs on the photo-degradation performance of CuO NRs as well as CuO/TiO2 heterostructure. The mechanism and role of photo-Fenton like catalyst in photo-degradation of dye was also illustrated in this work. The optimized CuO/TiO2 hybrid NR array structure exhibited the highest photo-degradation activity to date. With high aspect ratio, hybrid CuO/TiO2 NR-array can act as an excellent photocatalyst for PEC water splitting.
