本實驗使用水熱法並改變前驅物中鎳與鐵的濃度成長鎳鐵層狀雙氫氧化物於FTO基板上。更進一步在前驅物中加入硝酸銅改變前驅物中銅與鎳的濃度，以水熱法成長銅鎳鐵層狀雙氫氧化物於FTO基板上。首先，由掃描式電子顯微鏡影像可觀察到，不同的鎳鐵層狀雙氫氧化物試片與銅鎳鐵層狀雙氫氧化物試片皆均勻地片狀直立沉積在FTO基板上。由拉曼散射光譜可知，鎳鐵層狀雙氫氧化物試片與銅鎳鐵層狀雙氫氧化物試片皆具有金屬-氧振動模式之特徵峰。另外從X光繞射分析結果可知，鎳鐵層狀雙氫氧化物試片與銅鎳鐵層狀雙氫氧化物試片之結構為層狀雙氫氧化物之結構。因此綜合拉曼散射光譜與X光繞射結果，推測合成之樣品為層狀雙氫氧化物。利用鎳鐵層狀雙氫氧化物試片與銅鎳鐵層狀雙氫氧化物試片進行光芬頓降解四環黴素實驗，結果發現優化之銅鎳鐵層狀雙氫氧化物光芬頓降解四環黴素表現出較強的吸附能力及光降解性能，光照2小時後光催化反應移除59.4%的四環黴素，與鎳鐵層狀雙氫氧化物相比，降解性能有增強。由反應動力學可以發現，在加入銅後，銅鎳鐵層狀雙氫氧化物之光催化降解速率提升，代表銅的加入有助於光芬頓降解四環黴素，其中，銅鎳鐵層狀雙氫氧化物的降解速率常數為7.78 x10-3 min-1，約為鎳鐵層狀雙氫氧化物的1.2倍。

In this experiment, the hydrothermal method was used to grow nickel-iron layered double hydroxide nanosheets and copper-nickel-iron layered double hydroxide nanosheets on the FTO substrate. Firstly, it can be observed from the scanning electron microscope images that different nickel-iron layered double hydroxide test pieces and copper-nickel-iron layered double hydroxide test pieces are uniformly deposited on the FTO substrate in a sheet shape upright. According to the results of the Raman scattering spectrum and X-ray diffraction, it is speculated that the synthesized sample is layered double hydroxide. Using a nickel-iron layered double hydroxide test piece and copper-nickel-iron layered double hydroxide test piece to carry out the photo-Fenton degradation experiment of tetracycline, the results found that the optimized copper-nickel-iron layered double hydroxide photo-Fenton Degradation of tetracycline showed strong adsorption capacity and photodegradation performance. From the reaction kinetics, it can be found that after the addition of copper, the photocatalytic degradation rate of copper-nickel-iron layered double hydroxide increases, which means that the addition of copper is helpful for the degradation of tetracycline by photo-Fenton. Keywords: nickel-iron layered double hydroxide,copper-nickel-iron layered double hydroxide, photo-Fenton degradation of tetracycline
