研究了铂在几种离子液体中的电化学溶解。测试了不同的离子液体，评估其溶解Pt的潜力。评价了溶出速率和电流效率。主要的焦点是含氯离子液体：第一代，共晶基离子液体和第二代离子液体与离散阴离子。Pt的溶解只发生在1型共晶基离子液体中，最大值为100。溶解速率为192.2 g m− 2 h − 1，最大溶解速率为2.5 g m− 2 h − 1。ZnCl 2 -1-乙基-3-甲基咪唑鎓氯化物IL的电流效率为99%，1：1 ZnCl 2-胆碱氯化物IL的电流效率为9.090 g m-2 h-1和96%。溶解通过[PtClx]y−络合物的形成而发生。为了形成这些络合物，需要添加金属氯化物。此外，需要具有1.5V、优选2.0V的电化学窗口的IL来实现Pt溶解。所添加的金属盐需要具有高于1.5V的分解电势或者应该是Pt盐。
The electrochemical dissolution of Pt in several ionic liquids (ILs) was studied. Different ILs were tested assessing their potential to dissolve Pt. Dissolution rate and current efficiency were evaluated. The main focus was on Cl containing ILs: first generation, eutectic-based ILs and second generation ILs with discrete anions. Pt dissolution only occurred in type 1 eutectic-based ILs with a max. dissolution rate of 192.2 g m−2h−1and a max. current efficiency of 99 % for the ZnCl2–1-ethyl-3-methylimidazolium chloride IL, and 9.090 g m−2h−1and 96 % for the 1:1 ZnCl2–choline chloride IL. The dissolution occurred through the formation of [PtClx]y−complexes. To form these complexes, addition of a metal chloride was necessary. Furthermore, an IL with an electrochemical window of 1.5 V, preferably 2.0 V was required to achieve Pt dissolution. The added metal salt needed to have a higher decomposition potential than 1.5 V or should be a Pt salt.
