Synthesis of Rare Earth Element doped ZIF-67 derived NCNT interconnected conductive porous carbon from biowaste Hemp hurd Powder.
Abstract
The sp2 hybridized nanocarbon, such as carbon nanotubes (CNTs) and graphene, shows exceptional mechanical strength and electrical conductivity but has a less externally accessible surface area and few pores. In contrast, nanostructured porous carbon offers a large surface area and a lot of pore structures but has very poor electrical conductivity. Herein, we will synthesize rare-earth element (REE) containing nitrogen doped carbon nanotubes (NCNTs) interconnected porous carbon using a novel method, showing how sp2 nanocarbon and nanostructured porous carbon may be rationally hybridized to create hierarchical all-carbon nanoarchitectures that retain all the benefits of the individual constituent materials. We will use biowaste such as hemp hurd as the carbon precursor. The method involves synthesizing a Neodymium (Nd) and Cerium (Ce) doped ZIF-67 metal-organic frameworks (REE@Co-MOF) on the surface of hemp hurd powder. The REE@Co-MOF modified powder is then carbonized to produce REE@Co doped NCNTs interconnected porous carbon to make conductive, magnetic, and optically active carbon material. The effect of concentration of rare earth element on the thermal decomposition of precursors synthesis and its significance on nucleation and growth of doped nanoparticles will be studied through computational modelling. The optical properties such as absorbance, transmittance, fluorescence, Photoluminescence, and band gap measurement will be investigated. Similarly, AMF (Alternating Magnetic Field) generators and Physical Properties Measurement System (PPMS) will be used in magnetic property measurements. The method is a facile and environmentally friendly approach to produce REE@Co doped highly conductive NCNTs integrated porous carbon materials with ample potential of opt-magnetism, energy storage and conversion capability.
