Nanocarbon-inorganic hybrid materials for photocatalytic applications

纳米碳-无机杂化材料是一类在可持续能源和环境方面具有巨大应用潜力的新型纳米复合材料。这些杂化材料的优点来自于界面电荷和热传递过程，从而导致增强甚至新的性能。本项目旨在利用湿化学技术和原子层沉积技术设计和合成新型碳纳米管/石墨烯/金属氧化物和金属(氧)氮化物杂化材料。这些杂化材料将在使用合适的助催化剂的完整光催化系统中实施，然后对光催化氧化反应(即水净化)和还原反应(即水分解产生氢气)进行评估。第二个重点将是对界面的详细调查，界面将使用各种连接剂、聚合物和介质阻挡层进行修改。电荷转移过程将通过瞬变光谱和脉冲辐解进行研究。该项目将为环境和能源应用的下一代光催化剂的设计提供有价值的信息，从而为社会创造显着的效益。

Nanocarbon-inorganic hybrids are a new class of nanocomposites with great potential for applications concerning sustainable energy and the environment.The benefits of these hybrids origin from interfacial charge and heat transfer processes, which lead to enhanced and even new properties.This project aims to design and synthesize new CNT/graphene hybrids with metal oxides and metal (oxy)nitrides using wet-chemical techniques as well as atomic layer deposition. These hybrids will be implemented in complete photocatalytic systems involving suitable co-catalysts and then evaluated for both, photocatalytic oxidation reactions (i.e. water purification) as well as reduction reactions (i.e. hydrogen production from water splitting). A second focus will be the detailed investigation of the interface, which will be modified with various linking agents, polymers and dielectric barrier layers. The charge transfer processes will be investigated by transient spectroscopy and puls radiolysis. This project will provide valuable information towards the designing of next-generation photocatalysts for environment and energy applications and thus creating noticeable benefits for society.
