本研究在ZnCl2-EMIC離子液體中，利用電化學合金/去合金法在低於150oC以下的溫度製備出孔洞型鈀金雙金屬電極，藉由將鋅沉積於鈀金電極表面得到鈀金鋅合金，再將鋅剝除後即可得到孔洞型鈀金電極。分為循環伏安法(CV)法以及定電位法(CA)法兩種方式製備，CV法是利用循環伏安法多圈數掃描，在慢掃速10 mV s-1，電位範圍-0.3V~1.0V(vs.Zn)下，重複的沉積/剝除鋅後而製備孔洞形鈀金電極；CA法是利用定電位法，在電位-0.2V(vs.Zn)下沉積鋅，接著於電位1.0V(vs.Zn)下剝除鋅製備而得孔洞型鈀金電極。藉由掃描式顯微鏡(SEM)、元素分析(EDS)、X光繞射儀(XRD)、以及化學分析電子光譜儀(XPS)，去探討各種不同條件下製備而得的鈀金孔洞電極。最後將此電極應用在鹼性環境下葡萄糖的催化，並且與相同條件製備下的金和鈀孔洞型電極做個比較。

In this thesis, the porous Pd-Au bimetallic electrodes have been fabricated conveniently by electrochemical alloying/dealloying of Pd-Au-Zn alloy from a 40-60 mol% ZnCl2-EMIC ionic liquid at the temperature below 150oC. In this work, the cyclic voltammetry(CV) method and chronoamperometry(CA) method were used to fabricate the electrodes. In CV method, the porous Pd-Au electrode was obtained by multiple scan. The potential rang was -0.3 V to 1.0 V (vs. Zn) and the cyclic voltammetric scan rate was 10 mV s-1. During the cathodic process, reducible Zn(II) was electrochemically deposited onto a Pd-Au substrate. During the subsequent anodic process, Zn was removed from the substrate through electrochemical dissolution. In CA method, to prepare the porous Pd-Au bimetallic electrode, the Zn was deposited onto a Pd-Au substrate at -0.2 V (vs. Zn), and immersed in the electrolyte for an hour after deposition process. After that, anodic treatment was conducted at 1.0 V(vs. Zn). Scanning electron microscopy (SEM), energy dispersivespectrometer(EDS), X-ray diffractometer(XRD) and X-ray photo- electron spectroscopy(XPS) were used to characterize the porous Pd-Au bimetallic electrode. Finally, we used the same method to prepare the porous Pd and Au electrodes, respectively. These electrodes were used on glucose electrooxidation to compare results across studies.
