Abstract

Carbon Nanodots (CNDs) are semiconductor materials with a size below 10 nm. Carbon nanodots can be applied to several areas, such as biosensors, bioimaging, optoelectronics, and photocatalysis. Current research has shown that additional dopants to CNDs such as nitrogen (N) and sulfur (S), indicate a significant increase in electronic properties and fluorescence particularly for photocatalytic applications. Blackstrap molasse is cheap and easy to obtain due to it is a side result of sugarcane production. Hence, it has potential as carbon sources for carbon nanodots synthesis and production. The synthesis of S-doped Carbon Nanodots (S-doped CNDs) based on blackstrap molasses, H2O2, and garlic powder has been conducted by Microwave-Assisted Extraction (MAE). Characterization by FTIR indicates several functional groups mainly OH, C=O, C-H, and C-O-C with respective wavenumber of 3254,55 cm-1, 1633,56 cm-1, 1323,75 cm-1, and 1053,78 cm-1. The presence of stretching vibration at 1268,13 cm-1 as a new functional group of C-S, indicates the success of additional sulfur (S) dopant within carbon nanodots (CNDs). The fluorescence effect has been observed for carbon dots solution transforming light brown into blue color under UV light of 365 nm. These results have shown the effectiveness of the synthesis process of carbon nanodots (CNDs) from blackstrap molasses doped by sulfur from garlic using the MAE method.
