由於化石燃料的枯竭及其嚴重的環境影響，人們越來越關注利用地球豐富的材料將水和太陽能轉化為清潔和可再生的氫能源。光電化學水分解是一項能夠直接利用太陽光生產乾淨氫能源的技術，但是目前此項技術還有著很多的問題需要改善（例如，改善材料的電荷分離和轉移、提升光吸收、優化帶隙位置、降低成本和毒性、並增強穩定性和水分解動力學）。而本研究利用簡單的製程在銅箔基板上成功製備出具有奈米線結構的氧化亞銅，進行光電化學水分解量測發現氫化過後的氧化亞銅，能夠有效提升施加低外部電壓時的轉換效率。最後藉由旋轉塗佈氫氧化鐵，更近一步的提升介面處電場電子轉移。 最後利用同步輻射X光技術(XRD、XAS、AES、UPS)分析材料晶體結構組成與其化學半導體性質，再藉由SEM觀察材料表面形貌結構。

Due to the depletion of fossil fuels and their serious environmental impacts, more and more attention has been paid to use the earth's abundant materials to turn water and solar energy into clean hydrogen energy. Photoelectrochemical water splitting is a technology that can directly use sunlight to produce clean hydrogen energy, but there are still many problems to be improved, for example improving charge separation and transfer of materials, improving light absorption, optimizing bandgap locations, reducing costs and toxicity, and enhancing stability and water decomposition dynamics. In this study, the cuprous oxide with nanowire structure was successfully prepared on the copper foil substrate by a simple process. The photoelectric chemical water decomposition measurement showed that the cuprous oxide after hydrogenation could effectively improve the conversion efficiency when applying low external voltage. Finally, by spin-coating iron hydroxide, the interface of electric field enhanced electron transfer.
Eventually, techniques of synchrotron radiation X-ray (XRD, XAS, AES, UPS) were used to analyze the crystal structure and its chemical semiconductor properties.
