本論文在利用微陽極導引電鍍法(Micro-Anode Guided Electroplating, MAGE)製備銅鋅合金微柱，及其在0.1 M KHCO₃ 中進行二氧化碳還原反應(CO2 Electrochemical Reduction Reaction, CO2RR)之產物探討。本研究使用白金絲作為微陽極，將析鍍偏壓設定為4.6 V，並將析鍍間距控制在40 μm。鍍浴中固定磷酸二氫鉀在0.2 M、焦磷酸鉀在0.9 M 及五水合硫酸銅在0.05 M，藉由改變七水合硫酸鋅濃度(M)在0.15、0.16、0.17 及0.18，鍍浴之代號分別為CZ15、CZ16、CZ17 和CZ18 進行析鍍。析鍍所得合金微柱進行能量散射光譜(Energy Dispersive Spectrometer, EDS)和X 光繞射分析(X-ray Diffraction, XRD)分析確認其組成和結構。本製程所得微柱之優點具三維結構，可增大催化活性面積。隨後，利用氣相層析儀分析其還原產物，探討微柱中鋅和銅在二氧化碳還原的反應機制。利用循環伏安法在0.1 M KHCO₃ 下，分析計算其電化學活性表面積(Electrochemical Active Surface Area, ECSA)可評估其電化學催化性能，結果顯示CZ16 微柱(組成為Cu_68Zn_32)具有最大之電化學活性表面積(ECSA)為778.3 cm²。

This study focuses on the preparation of copper-zinc alloy microcolumns using Micro-Anode Guided Electroplating (MAGE). It investigates their products in the electrochemical reduction reaction of carbon dioxide (CO2RR) in 0.1 M KHCO₃ electrolyte. A platinum wire is employed as the micro-anode with a deposition bias set of 4.6 V, and the spacing between the electrodes is maintained at 40 μm. The plating bath consists of fixed concentrations of 0.2 M potassium dihydrogen phosphate, 0.9 M potassium pyrophosphate, and 0.05 M copper (II) sulfate pentahydrate. By varying the concentration of heptahydrate zinc sulfate (M) to 0.15, 0.16, 0.17, and 0.18, the plating baths are denoted as CZ15, CZ16, CZ17, and CZ18, respectively. The obtained alloy microcolumns conduct Energy Dispersive Spectrometer (EDS) and X-ray Diffraction (XRD) analyses to verify their composition and structure. The produced microcolumns provide benefits due to their three-dimensional structure, which increases the catalytic active surface area. Gas chromatography analysis is performed to examine the reduction products and investigate the reaction mechanism of zinc and copper in CO2 reduction. Electrochemical Active Surface Area (ECSA) is calculated using cyclic voltammetry in 0.1 M KHCO₃ to evaluate the electrochemical catalytic performance. The results reveal that CZ16 micro columns (comprising Cu_68Zn_32) exhibit the maximum ECSA of 778.3 cm².
