Preparation and characterization of F-, O-, and N-containing carbon nanoparticles for pH sensing
نویسندگان
چکیده
A novel sensing system was designed for pH measurements based on the enhanced and quenched photoluminescence (PL) UV–Vis absorption of diluted water solutions F-, O-, N-containing carbon nanoparticles (FON-CNPs). These FON-CNPs were solvothermally synthesized, dissolved, ultra-filtrated, separated by thin-layer chromatography. The total fluorine content in them found to be 1.2–1.5 mmol per gram. Their TGA showed a weight loss 52.7% because thermal decomposition detachment surface groups partial burning functionalized shell core at temperatures below 1200 °C. TEM Raman data confirmed presence graphitic structures core. From results ATR FTIR spectroscopies, we that incorporates different functional covering include carboxyl, phenolic, carbonyl groups. Heterocyclic amino trifluoromethyl supporting hydrophobicity also found. We suggested possible reasons responses obtained with considering dependent de-protonation change.
