Solution processing has emerged as a promising option for the preparation of functional materials with methods that tend to be cheap, less energy intensive, and allow for high throughput and large area deposition. A recently developed method, whereby a binary thiol–amine solvent mixture is used to dissolve bulk oxides, chalcogenides, or elemental materials to yield molecular precursor inks for the deposition of phase pure chalcogenide materials, has recently garnered attention for applications in optoelectronics, thermoelectrics, and electrocatalysis. Presented here is a summary of reports on the application of this “alkahest” method for the deposition of electrocatalytic materials. Ink formulations drawing on the vast library of bulk precursor solutes have already resulted in a large collection of synthesized functional materials, with room still to explore new, or less studied, materials. Additionally, as is seen for the electrocatalysts, engineering of inks and deposition procedures can lead to higher performance through optimized morphology and form factors.

使用硫醇胺溶液处理方法制备电催化剂

溶液处理已经成为一种制备功能材料的有前途的选择，其方法往往价格便宜，能耗较低，并且允许高通量和大面积沉积。最近开发的一种方法，通过使用二元硫醇-胺溶剂混合物来溶解本体氧化物，硫族化物或元素材料，以生产用于沉积相纯硫属元素化物材料的分子前驱体墨水，最近在光电，热电，和电催化。本文介绍了有关这种“碱性”方法在电催化材料沉积中的应用的报告摘要。利用庞大的散装前体溶质库建立的油墨配方已经产生了大量的合成功能材料，仍有探索新材料或研究较少的材料的空间。另外，如对于电催化剂所见，油墨的工程设计和沉积程序可以通过优化的形态和形状因数来提高性能。
