Four types of luminescent nitrogen-doped carbon dots (C-dots) are prepared by using glucose (G) or citric acid (C) as carbon source, and dopamine (D) or 4,7,10-trioxa-1,13-tridecanediamine (T) as nitrogen source, named GD-C-dots, GT-C-dots, CD-C-dots and CT-C-dots. The investigation on the optical, pH-sensitivity and photovoltaic properties of these C-dots illustrates that nitrogen source plays a...
Carbonized nanostructured polyaniline (C.PANI) was hydrothermally treated in 1moldm −3 KOH at 200°C. The treatment caused significant reduction of micropore volume but negligible changes in mesoporous domain, as evidenced by nitrogen adsorption measurements, as well as significant increase of surface N/C and O/C ratios, as evidenced by XPS method. In comparison to the C.PANI precursor,...
Nitrogen-containing nanostructured carbon materials, C-nanoPANI, C-nanoPANI-DNSA and C-nanoPANI-SSA, were prepared by the carbonization of nanostructured polyaniline (PANI) doped with sulfuric acid, 3,5-dinitrosalicylic acid (DNSA), and 5-sulfosalicylic acid (SSA), respectively. The charge storage ability of these materials was investigated in alkaline solution. It was found that the specific capacitance...
