Title : N-doped nanographene quantum dots for environmental applications and sensors
Abstract:
Functionalizing of carbon nanomaterial to meets the criteria for detection of hazardous pollutants caused by human activities is a challenge but solution to many global pressing problems that caused climate changes such as unmanaged release of hazardous gases such as volatile organic compounds, Nitrogen dioxide, NO2, ammonia NH3 and Hydrogen sulphide are seriously affecting our environment and human health and may even lead to loss of lives, therefore, this necessitated the effective ways and devices for detection of these toxic gases in all setting including industrial areas and cities. And toxic and carcinogenic pollutant, such as organic and inorganic (heavy metal) include Pb(II), Cr(VI),CThed(II),Hg (II), As(V) and Ni(II) are regarded as essential pollutant deteriorate our environment and threatening our health and environment. This work aim to develop Nitrogen doped-Nanographene quantum dots (N-NGQDs) from waste plastic and investigates their prospect as an innovative device for environmental application and sensors. The nanographene characterized using different characterization techniques such as X-ray diffraction (XRD), Thermalgravimetric (TGA), Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR), X-ray Photoelectron Spectroscopy ( XPS), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM). Evaluated their sensing effective performance for NO2 gas and also detect the presence of Cobolt and Nickel by fluorescence.
