This M2 intership aims to develop a bottom-up synthesis of diamond nanoparticles, based on sacrificial templates (silica beads or fibers) on which nanometric diamond seeds will be attached via electrostatic interactions. Diamond growth will be achieved by an exposure of the seeded templates to a micro-wave assisted CVD plasma (MPCVD). Growth parameters will be adjusted to select the size, the shape and the concentration of chemical impurities (nitrogen, boron) in nanodiamonds. After CVD growth, nanoparticles will be collected by dissolution of the templates. Their crystalline structure, morphology and surface chemistry will be characterized at CEA NIMBE by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman, infra-red (FTIR) and photoelectrons (XPS) spectroscopies.

The aim of this intership is to investigate the potential of nanodiamonds in producing solar fuels (H2 or CO2 reduction) by photo/electro-catalysis through a collaboration between the NIMBE team (Hugues Girard and Jean-Charles Arnault), which specializes in nanodiamond synthesis and SOLEIL team (Benedikt Lassalle, LUCIA), which has expertise in electrocatalysis and X-ray absorption spectroscopy (XAS) characterizations.

This project proposes an in-situ study, during the VACNT formation, making it possible to analyze the nature and structure of catalytic nanoparticles, as well as the potential formation of disordered carbon influencing the height limitation of CNTs, is very important. This study will be carried out on a local scale using an environmental TEM (E-TEM NanoMax from the TEMPOS Equipex) to analyze the catalytic nanoparticles and the carbon being formed around individual particles.

The aim of this project is to determine whether radiation chemistry (i.e. induced by ionising radiation) can be used to explore the reactivity of titanium dioxide nanoparticles in the presence of propionic acid.
