Facile approach to the synthesis of carbon nanodots and their peroxidase mimetic function in azo dyes degradation

Simultaneous electrochemical sensing of thallium, lead and mercury using a novel ionic liquid/graphene modified electrode

“…The composite ( Fig. 1 e(2)) displays that except the bands of Gr, there are additional bands at 1520 and 1255 cm -1 corresponding to the stretching vibrations of the C-N bonds in the aromatic system of pyridinium, and 895 cm -1 and the peaks at 790, 642 and 578 cm -1 are corresponding to the stretching vibrations of P-F, demonstrating the existence of both OPFP and Gr in the composite [40,43]. Also, The XRD diffraction pattern of the prepared Gr is shown in Fig.…”

Photoluminescent Detection of Nitrite with Carbon Nanodots Prepared by Microwave-assisted Synthesis

“…3 Photoluminescent carbon nanodots (CNDs) prepared via several synthetic methods are of particular interest because of their higher photoactivity, lower toxicity, and less-expensive cost compared with heavy-metal contained quantum dots. 4 An increasing number of applications based on CNDs have been carried out, such as cell imaging, 5 dye degradation, 6 pH determination, 7 chemiluminescence, 8 and immunoassay. 9 These CND applications make the most of several favorable properties of CNDs such as size-and excitation wavelength-dependent luminescence emission, photostability, and biocompatibility.…”

Fluorescent carbon nanodots for optical detection of fluoride ion in aqueous media

“…Carbon nanodots were synthesized from N-octylpyridinum hexafluorophosphate (OPPF 6 ) by a microwave assisted ionic liquid method [21]. Synthesis of OPPF 6 was done according to the reported procedure [22].…”
