Green Carbon Dots (GCDs) for Photocatalytic Hydrogen Evolution and Antibacterial Applications

摘要

Microwave technique was used to synthesize Green Carbon Dots (GCDs) from Aloe vera leaves because of easy to apply, accessible, time-saving, cheap, safe and environmental-friendly way. The prepared GCDs/TiO2 composite was obtained via sensitization of TiO2 with the help of GCDs. The characterization of the GCDs/TiO2 was made optically, structurally and morpho- logically. The photocatalytic hydrogen activity of GCDs/TiO2 was investigated under visible light (λ>420 nm) irradiation in the aqueous solution using triethanolamine (TEOA) sacrificial electron donor.
