Nanocarbon-inorganic hybrid materials for photocatalytic applications

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方面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传热过程，从而增强了材料的性能，甚至产生了新的性能。该项目旨在利用湿化学技术和原子层沉积技术，设计和合成新的碳纳米管/石墨烯杂化金属氧化物和金属（氧）氮化物。这些混合物将在包含合适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（即水裂解制氢）进行评估。第二个重点将是界面的详细研究，它将用各种连接剂、聚合物和介电阻挡层进行修饰。电荷转移过程将通过瞬态光谱和脉冲辐射分解进行研究。该项目将为设计用于环境和能源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。

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.
