Two-Step and Green Synthesis of Highly Fluorescent Carbon Quantum Dots and Carbon Nanofibers from Pine Fruit.
To green synthesis of highly yield photoluminescence carbon nanofibers/carbon quantum dots by pine fruit the ball milling assisted hydrothermal method was served. Different analysis such as XRD, EDS, elemental mapping and FT-IR analysis were used to study the product structure. The optical properties of the synthesized carbon nanomaterials were investigated by UV-Vis and PL analysis. Also, the effects of hydrothermal time and temperature on the PL intensity were studied. To study the product size and morphology SEM and TEM analysis were served. Also, the nucleation and growth mechanism was studied by TEM images. The results showed the product is composed of very tiny nitrogen-doped carbon dots and carbon nanofibers with high photoluminescence intensity. The photocatalytic activity of the product was investigated by degradation of six dyes namely Acid blue, Eosin Y, Erichrome Black T, Methylene blue, Methyl orange and Methyl. The results showed the product has high photocatalytic activity and it can degrade the dyes with creation reactive oxide species in the aqueous solution. The surface activity of the product was also investigated and it was found it can adsorb Pb2+ and Cd2+ from the water with 100% efficiency. The results showed we can synthesis of useful carbon nanomaterials with high photoluminescence intensity, highly photocatalytic activity and surface adsorption via a simple and fast method with the pine fruit.
