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.

纳米碳-无机杂化材料是一种新型的纳米复合材料，在可持续能源和环境领域具有巨大的应用潜力。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。本项目旨在设计和合成新型的碳纳米管/石墨烯杂化材料与金属氧化物和金属（氧）氮化物，使用湿化学技术以及原子层沉积。这些混合物将在涉及合适的助催化剂的完整光催化系统中实施，然后评估光催化氧化反应（即水净化）以及还原反应（即水分解制氢）。第二个重点将是详细调查的接口，这将是修改与各种连接剂，聚合物和介电阻挡层。电荷转移过程将通过瞬态光谱和普尔斯辐解进行研究。该项目将为设计用于环境和能源应用的下一代光催化剂提供有价值的信息，从而为社会创造显着的效益。
