Abstract This project aims to obtain a new class of hybrid nanomaterials, which are described by the integration of photoluminescent carbon nanodots (CNDs), doped or not with heteroatoms (N, S, B and P), and silver (Ag) or gold (Au) plasmonic nanostructures. This will be directed towards to the application of these in the conversion of solar energy to fuels. In these nanomaterials, we are interested on preparing core@shell structures in which the CNDs appear as the core, while the plasmonic nanostructures as the shell. In this sense, the first stage of this project will focus on the development and optimization of synthetic routes for such structures, in which we intend to achieve excellent control over their uniformity, morphology, size and composition. In the second part of this project, the synthesized nanomaterials will be used as photocatalysts targeting the production of H2 fuel from the photocatalytic water splitting reaction. In this case, we will investigate the photocatalytic activity of these nanomaterials as function of their morphologies, sizes and compositions. In the third step, we will expand this study to verify how the hybrid nanomaterials and photocatalytic properties are influenced by the combination of the CNDs up-conversion photoluminescence effect and the phenomena of localized surface plasmon resonance of the Ag or Au plasmonic nanostructures. It is expected that based on this knowledge, we can optimize quite accurately the photocatalytic properties of hybrid nanomaterials composed by CNDs and plasmonic nanostructures. | |
