Functionalization of cocoa shell (CS) surfaces using nanoparticles and their application in CO
2
storage

T
he aim of this research is to investigate how the covalent grafting of cocoa shell surface (CS) may improve its activity for the
adsorption of CO
2
at 20°C. Pure cocoa shells (CS) are agricultural by-products, usually inexpensive and abundantly available.
They were functionalized by salinization and subsequent immobilization of cobalt nanoparticles (Co-NPs). In parallel, some carbon
material was generated by hydrothermal treatment then post functionalized to increase the cocoa shell specific surface. Finally some
core-shell nanoparticles have been also synthetizedusing cocoa shell as a core and zinc oxide as a shell, then some post-functionalization
with nanoparticles insertion were added. The physical and thermal properties of the adsorbents like analysis stability, surface charge
and morphology were investigated by FTIR, SEM, TEM, EDX, BET, DSC and zeta potentiometry techniques. The performance for
the CO
2
capture was investigated and the high adsorption capacity was mainly attributed to their original structure.
Biography
Julien Vieillard has his expertise in analytical chemistry in order to promote innovative material or new application. Thus, in the recent year, we tried to promote
natural bio waste for CO
2
sorption. Actually, our research is also focused to develop original optical, electrochemical biosensors and antibacterial treatment for
metallic surface.
