Synthesis and characterization of Nickel Oxide with Nitrogen quantum Carbon dots as nanoadsorbent (NiO-NCQD) nanocomposite

This research deals with the manufacture of nickel oxide nanoparticles NiO, it has been characterized by Field emission scanning electron microscopy (FESEM), and Fourier Transform Infrared (FTIR), and their radii were range (۱۰-۲۰) nm and frequency (۵۸.۴۹%), where did not exceed the largest particles is (۶۰ nm).  Nitrogen carbon quantum dots (NCQD) were prepared based on a carbon-rich source and a nitrogen-rich source with a heat source. Nitrogen carbon quantum dots (NCQD) were prepared from L-glutamic acid as a carbon source and ethylene diamine (EDA) as a nitrogen-rich source depending on the source of heat: (reflex, autoclave, UV-digestion, oven, and microwave). The (NCQD) synthesis was characterized using spectral scanning (UV-VIS), then, the effect of its quenching ratio was studied using a sulfuric acid solution, it was found that the best thermal method is the autoclave then a UV-digester then oven and microwave.  Nickel oxide-nitrogen quantum carbon dots (NiO-NCQD) are prepared from a mix between NiO nanoparticles with nitrogen carbon quantum dots as nano-adsorbent. (NiO-NCQD) has been characterized by Fourier Transform Infrared (FTIR) and energy-dispersive X-ray (EDX).
