    • 多孔性的銀電極表面，可以藉由電化學合金/去合金化法在ZnCl2-EMIC融鹽系統中製備出多孔性的銀電極表面，操作溫度低於150 oC，且過程中不需用到任何具有腐蝕性的酸液與鹼液。多孔性銀電極表面的多孔性結構可以藉由改變鋅銀合金相的組成而改變，也就是說可以簡單地利用改變鋅沈積的電量、沈積的電位或電流、改變電沈積過程以及氧化剝除過程的操作溫度來控制。
    多孔性銀電極可被利用來將氯仿以電化學方式還原成甲烷。同時，這樣的電化學還原過程可以有效的將氯仿的毒性去除。和拋光的銀電極相比，多孔性的銀電極具有較大的活性表面，因此可以有效的將氯仿還原。
    此外，經過沈積以及氧化剝除的步驟後，整個融鹽系統中的二價鋅離子並不會因此而改變，因此融鹽可重複利用。

    The porous silver surfaces have been fabricated conveniently by electrochemical alloying/dealloying of Ag-Zn alloy from a ZnCl2-EMIC ionic liquid at temperatures below 150°C without using any other corrosive acids or bases. The porous structure and surface morphologies of the porous silver films are dependent on the composition of the Ag-Zn surface, which in turn can be manipulated by the quantity of the zinc deposited on the silver surface, deposition potential, deposition current, and deposition/stripping temperature.
    The application of the fabricated porous Ag electrode was tested for the electrochemical reduction of chloroform to methane. At the same time, the electrochemical reduction process may contribute to an effective process for detoxification of chloroform. Compared to the polished Ag electrode, the porous Ag electrode has a much higher active surface area and is an effective electrode for the reduction of chloroform.
    Furthermore, because the Zn(II) species used in the deposition step returned back to the ionic liquid during the dealloying step, the composition of the ionic liquid is essentially unchanged and thus can be reused.
