This project describes an integrated action within the DFG-NSFC program targeting at a research collaboration between Harbin Institute of Technology, China (HIT) and Clausthal University of Technology, Germany (TU Clausthal). The joint research aims at the development of advanced analysis methods and design in situ techniques for the study of the interfacial properties and interfacial reactions of ionic liquids (ILs) at semiconductors, carbon based materials and their composites for energy applications. The developments of ILs as media for the production of electroactive materials and of ILs as electrolyte for sustainable energy technologies are of great interest, due to their unique physical and chemical properties, such as large electrochemical window and negligible vapor pressure. However, the relation between a detailed fundamental understanding of the interfacial properties and the energy efficiency of the device has to be addressed. In order to ensure the successful project implementation, the contributions and details of the research methodology of both cooperators are clearly defined. HIT will focus on the preparation of different kinds of materials, including nanostructured semiconductors, carbon based materials (carbon nanotube, graphene materials and porous carbon frameworks) and their composites (Si/graphene, Ge/graphene and TiO2 /carbon nanotube). TU Clausthal will mainly study the interfacial structure and interfacial reactions of ILs at the interface by in situ techniques, such as in situ AFM, in situ XPS and electrowetting. The projects goals will be pursued by investigating the effect of ions of the IL, structure of the substrate, metal speciation, electrode potential, and temperature using a combined electrochemical, chemical, and spectroscopic approach taking advantage of both ex-situ and in-situ techniques. Finally, these optimized materials (ILs, semiconductors and carbon based materials) will be integrated for sustainable energy devices. The integrated action will be executed via mutual exchanges and visits of the personnel involved from the two institutions. We provide some technical background information, describe the open problems to be addressed, and develop a plan for the collaborative research and publication efforts. The ability of the researchers involved to carry out the proposed research is demonstrated by a summary of their relevant previous scientific and management experience.

该项目描述了针对Harbin Technology，中国（HIT）和德国克劳斯塔尔技术大学（TU Clausthal）的DFG-NSFC计划中的一项集成行动。联合研究旨在开发先进的分析方法和原位技术，以研究半导体，基于碳的材料及其复合材料的离子液体（ILS）的界面特性和界面反应。由于其独特的物理和化学性能，例如大型电化学窗口和可忽略不计的蒸气压力，因此，ILS作为产生电活性材料和ILS作为电解质的媒体的发展引起了人们的极大兴趣。但是，必须解决对界面特性的详细基本理解与设备能源效率之间的关系。为了确保成功的项目实施，明确定义了两个合作者研究方法的贡献和细节。 HIT将重点放在制备各种材料的准备上，包括纳米结构的半导体，碳材料（碳纳米管，石墨烯材料和多孔碳框架）及其复合材料（SI/Chapeene，Ge/Ge/Ge/Chapeene和Tio2/Tio2/Carbon Nanotube）。 Tu Clausthal将主要研究ILS在界面上的界面结构和界面反应，例如原位技术，例如原位AFM，原位XPS和电网。通过研究IL的结构，底物的结构，金属物种的结构，电极电位以及温度，使用联合的电化学，化学和光谱方法，利用EXITU和原地技术，将实现项目目标。最后，将将这些优化的材料（ILS，半导体和基于碳的材料）整合为可持续能源设备。综合行动将通过两个机构涉及的人员的相互交流和访问来执行。我们提供一些技术背景信息，描述要解决的开放问题，并为合作研究和出版工作制定计划。涉及的研究人员进行拟议研究的能力通过了其先前的科学和管理经验的摘要来证明。
