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 DFG-NSFC 计划中的一项综合行动，旨在中国哈尔滨工业大学 (HIT) 和德国克劳斯塔尔工业大学 (TU Clausthal) 之间的研究合作。该联合研究旨在开发先进的分析方法和原位设计技术，用于研究离子液体（IL）在半导体、碳基材料及其能源应用复合材料中的界面性质和界面反应。由于其独特的物理和化学性质，例如大的电化学窗口和可忽略的蒸气压，IL作为电活性材料生产的介质和IL作为可持续能源技术的电解质的发展引起了人们的极大兴趣。然而，必须解决对界面特性的详细基本理解与设备能量效​​率之间的关系。为了确保项目的成功实施，双方的研究方法的贡献和细节都得到了明确的界定。哈尔滨工业大学将重点研究不同类型材料的制备，包括纳米结构半导体、碳基材料（碳纳米管、石墨烯材料和多孔碳骨架）及其复合材料（Si/石墨烯、Ge/石墨烯和TiO2/碳纳米管）。克劳斯塔尔工业大学将主要通过原位AFM、原位XPS和电润湿等原位技术研究ILs的界面结构和界面反应。该项目的目标将通过利用电化学、化学和光谱相结合的方法，利用异位和原位的优势，研究离子液体的离子、基底结构、金属形态、电极电位和温度的影响来实现。技术。最后，这些优化的材料（离子液体、半导体和碳基材料）将被集成用于可持续能源设备。一体化行动将通过两机构相关人员的相互交流和互访来实施。我们提供一些技术背景信息，描述要解决的开放问题，并制定合作研究和出版工作的计划。参与研究的研究人员进行拟议研究的能力通过对其以往相关科学和管理经验的总结来证明。
