Abstract:

Here we propose an alternative method to reduce Sclerocarya birrea (Rich) hochst peel waste as a precursor carbonaceous material for the production of nanoparticles (carbon quantum dots (QPCs)). Our research therefore consists mainly in developing an alternative method for the valued because they are in quantity in the northern part of Cameroon. In general, hydrothermal carbonization is a physico-chemical process of converting organic compounds into structured carbon, sometimes PQC. The methodology developed consists of a complete synthesis method, including hydrosolvothermal carbonization under microwave irradiation of the starting carbon source, addition to the carbonized mass by activating in an acid medium and functionalized by jets of heteroatoms in condition anoxic, a volume of water acting as a solvent which facilitates the extraction of PQC associated with microwave radiation followed by membrane filtration and centrifugation. To characterize the PQC, we evaluate: thermal analysis, TEM, SEM, DRX, specific surface, quantum efficiency. With an FT-IR and function analysis by Boehm's method respectively the different functional groups present in the structure and as well as the levels of acidity and base on the surface. The evaluation of the properties of PQC in aqueous medium to know the global surface charge of the materials the pHpcz and the behavior of the PQC in agitation, in interaction with water to evaluate the course of pH over time (pHeq). All these analyzes have made it possible to better understand the morphology, the surface functions, the specific surface, the studies of optical properties to allow a possible application in the field of biomolecular analytical chemistry to immobilize/ capture the bacterial biomolecules present in the food industry for control the regulation of food products in bacteriological quality.
