摘要

研究有机/离子液体杂化系统是设计越来越复杂的界面的踏脚石，用于广泛的应用-光伏，光催化，二氧化碳还原和析氢反应。要很好地理解离子液体有机层的形成过程，需要可靠和系统的实验和理论方法。在这里，我们采用电化学方法与受控实验装置相结合的方法，详细表征了离子液体在Bi（111）表面吸附四苯基卟啉和层形成过程。对这些复杂体系的研究使我们得出结论，离子液体分子结构和粘度对层的形成有很大的影响。

Adsorption of porphyrins on bismuth – Ionic liquid interface: Model adsorbates to study organic/ionic liquid hybrid systems

Studying organic/ionic liquid hybrid systems is a stepping stone towards designing increasingly complex interfaces for a wide range of applications: photovoltaics, photocatalysis, CO₂ reduction, and hydrogen evolution reactions. A good understanding of organic adlayer formation processes from ionic liquids requires a reliable and systematic experimental and theoretical approach. Here, we employ a combination of electrochemical methods together with a controlled experimental setup to characterise in detail the adsorption and adlayer formation processes of tetraphenylporphyrin from ionic liquids on Bi(111) surface. The investigation of these complex systems leads us to conclude that the adlayer formation highly depends on the ionic liquid molecular structure and properties.
