Abstract

Utilization of coconut shell soot as raw material for making carbon dots has been successfully carried out. This study used coconut shell soot with 5 M HNO3 acid oxidation method which is then the Carbon dots characteristics were determined using UV light, UV-Vis, TEM analysis, and functional group analysis with FT-IR. Coconut shell soot is obtained by pyrolysis method. The heating process using a furnace carried out for 2 hours at 400 °C. Carbon dots produced by heating with 5 M HNO3 for 12 hours at 100 °C, centrifuged and dialysis. The yield of carbon dots was 87%. The FT-IR spectrum shows that the Carbon dots formed produce OH group absorption at 3396 cm-1, absorption of C = C at wave number 1637 cm-1, absorption of CO groups, and CH at wave number 1339 cm-1, and 835 cm-1. Analysis with Transmission Electron Microscopy shows that carbon dots has an average diameter of 1.50 nm. Absorbance spectrum analysis (UV-Vis) results in the appearance of new uptake showing the electron transition at a wavelength of 307 nm and giving green fluorescence under UV light.
