在中性碘化物/三碘化物水溶液中溶解Pt的可行性（尽管需要提高温度），以及从这些溶液中电沉积Pt到碳（用于设想的规模化工艺的阴极材料）上的可行性。PtI62 （(aq)）的还原很容易，生成PtI42 （(aq)）作为稳定的中间体，可以通过更慢的反应进一步还原为Pt。该系统可以为从二次材料中选择性回收Pt的环境友好，节能的过程奠定基础。随着需求的增加，制定有效的战略物资回收程序是很重要的。(C) 2013中国电化学会。版权所有。
The feasibility was demonstrated of Pt dissolution in neutral aqueous iodide / tri-iodide solutions, albeit requiring elevated temperatures, and of Pt electrodeposition from such solutions on to carbon, the cathode material to be used in the envisaged scaled process. Reduction of PtI62 ((aq)) was facile, producing PtI42 ((aq)) as a stable intermediate that could be further reduced to Pt by a much slower reaction. This system could form the basis of an environmentally benign, energy efficient process for the selective recovery of Pt from secondary materials. It is of importance that efficient recovery processes for strategic materials be developed as demand increases. (C) 2013 The Electrochemical Society. All rights reserved.
