Fabrication of novel Ag/g‐C₃N₄ electrode for resveratrol sensors

Abstract

Ag/g‐C3N4 is fabricated and used as an electrode for determining trans‐resveratrol concentration. The compositional and structural characteristics of the as‐fabricated Ag/g‐C3N4 are studied through X‐ray diffraction, transmission electron microscopy, and energy dispersive spectroscopy. Additionally, the electrochemical behavior of Ag/g‐C3N4 is investigated using cyclic voltammetry. According to the experimental results, 1 wt%Ag/g‐C3N4 exhibits an oxidation peak at 0.48 V, with a low detection limit (1.88 × 10−7 M) and satisfactory correlation coefficient (0.9975), suggesting that the proposed Ag/g‐C3N4 electrode can be successfully used for detecting trans‐resveratrol.

Microwave‐assisted synthesis of the Fe2O3/g‐C3N4 nanocomposites with enhanced photocatalytic activity for degradation of methylene blue

“…[13] Pale yellow g-C 3 N 4 , in the form of nanoparticles, nanotubes, or nanosheets, is a nonmetallic polymer semiconductor [14] that enjoys excellent properties such as high thermal and chemical stability, [15] nontoxicity, [16] biocompatibility, [17] and the narrow bandgap of 2.7 eV. [18] However, due to the rapid recombination of photoinduced electron-hole pairs and low specific surface area, g-C 3 N 4 suffers from slow reaction kinetics in photocatalysis. [19] So, various strategies such as metal or nonmetal doping, are followed to overcome the above disadvantages and increase the photocatalytic efficiency of pure g-C 3 N 4 .…”
