AbstractStrong photoluminescent carbon nanoparticles (CNPs) were synthesized by one-pot solvothermal method using tartaric acid and tyrosine as starting materials and ethylene glycol as solvent. The as-prepared CNPs were characterized by XRD, TEM, FTIR and fluorescence spectroscopy (FL). The results show that the CNPs are well dispersed and narrowly distributed amorphous and spherical particles with diameter of 10 similar to 30 nm. The CNPs are rich in hydroxyl and carboxyl groups on the surface with highly hydrophilic nature. The emission wavelength of CNPs depends on the excitation wavelength. The effects of reaction temperature and the mass ratio of tartaric acid to tyrosine on emission intensity of the CNPs were also investigated. The CNPs also show excellent photocatalytic performance for photodegradation of naphthol green (NG) under visible light in the presence of H2O2. The results indicate that the degradation efficiency of NG reaches 96% with initial concentration of 130 mg.L-1 within 3.5 h. The hydroxyl radicals (center dot OH) are detected in the reaction.
