Abstract:
Amine-functionalized graphitic carbon nitride (NH2/GCN) nanosheets photoluminescence, catalytic properties and excellent water dispersion stability were prepared and characterized by a variety of different analytical and spectroscopic techniques. The well-dispersed NH2/GCN nanosheets were found to exhibit remarkable pH sensing sensitivity at an ambient temperature with desirable broad detection range (1 ≤ pH ≤ 12). Moreover, upon incorporating silver nanoparticles (Ag NPs), the Ag-NH2/GCN nanocomposites showed excellent performances for catalytic reduction of 4-nitrophenol (4-NP) in NaBH4 with a superior rate constant (k) of 0.1594 s-1 within as short as 30 s. The NH2/GCN and Ag-NH2/GCN nanocomposites reported herein therefore render prospective applications as sensitive pH and practical catalytic applications. © 2017 Wiley-VCH Verlag GmbH & Co.
