“…Up to now, as a transition metal oxide, CuO was demonstrated to be a promising catalyst for the thermal decomposition of AP [25]. Moreover, our group confirmed that g-C 3 N 4 can also accelerate the thermal decomposition process [30]. It was anticipated that the direct growth of CuO on g-C 3 N 4 will not only avoid the agglomeration of nano-sized CuO, but also efficiently accelerate the electron transfer rate between them.…”

Novel graphitic carbon nitride/CuO (g-C3N4/CuO) nanocomposite was synthesized through a facile precipitation method. Due to the strong ion-dipole interaction between copper ions and nitrogen atoms of g-C3N4, CuO nanorods (length 200–300 nm, diameter 5–10 nm) were directly grown on g-C3N4, forming a g-C3N4/CuO nanocomposite, which was confirmed via X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), and X-ray photoelectron spectroscopy (XPS). Finally, thermal decomposition of ammonium perchlorate (AP) in the absence and presence of the prepared g-C3N4/CuO nanocomposite was examined by differential thermal analysis (DTA), and thermal gravimetric analysis (TGA). The g-C3N4/CuO nanocomposite showed promising catalytic effects for the thermal decomposition of AP. Upon addition of 2 wt % nanocomposite with the best catalytic performance (g-C3N4/20 wt % CuO), the decomposition temperature of AP was decreased by up to 105.5 °C and only one decomposition step was found instead of the two steps commonly reported in other examples, demonstrating the synergistic catalytic activity of the as-synthesized nanocomposite. This study demonstrated a successful example regarding the direct growth of metal oxide on g-C3N4 by ion-dipole interaction between metallic ions, and the lone pair electrons on nitrogen atoms, which could provide a novel strategy for the preparation of g-C3N4-based nanocomposite.

“…In the C1s core level spectrum (Figure 4(c)), the four deconvoluted peaks appear at 284.78, 285.36, 287.24, and 288.78 eV. These peaks can be assigned to C-C sp 2 (284.78 eV) and C-C sp 3 (287.24 eV) in imidazole [21,22], sp 2 -bonded carbon (288.78 eV) in aromatic rings of g-C 3 N 4 (N-C=N), and the C-C coordination of the surface adventitious carbon (285.36 eV) [12]. For the Co2p core level spectrum (Figure 4(d)), the duplex of Co2p appears at 779.85 eV for Co2p 3/2 with a satellite peak at 783.94 eV and at 795.71 eV for Co2p 1/2 with a satellite peak at 801.14 eV.…”

“…Recently, graphitic carbon nitride (g-C 3 N 4 ), which is a polymeric layered material, structurally analogous to graphene, has emerged as a prospective material for use in electrochemistry [10,11]. Besides its thermal and chemical stability, graphitic carbon nitride possesses metal-free and multiple structural defects, tunable electronic structure, mechanical stability, and high electrical conductivity [12]. Zeolitic imidazolate frameworks (ZIFs) are a subclass of metal-organic frameworks (MOFs).…”

In the present paper, the ZIF-67/g-C3N4 composite was synthesized and utilized as a modifier for a glassy carbon electrode for the simultaneous voltammetric determination of uric acid (URA) and acetaminophen (ACE) with cetyltrimethylammonium bromide (CTAB) as a discriminating agent. The composite was characterized using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and nitrogen adsorption/desorption isotherms. The obtained ZIF-67/g-C3N4 composite exhibits good textural properties (specific surface area: 75 m2·g−1) and is stable in water with a pH range of 3 to 10. The ZIF-67/g-C3N4-modified electrode combined with CTAB as a discriminating agent possesses excellent catalytic electrochemistry towards URA and ACE with well-defined electrochemical responses. The electrochemical kinetics study is also addressed. The linear relation of the oxidation peak current of URA and ACE and the concentration ranging from 0.2 μM to 6.5 μM provide a detection limit of 0.052 μM for URA and 0.053 μM for ACE. The proposed method is well-suited to simultaneously analyze URA and ACE in human urine with comparable results with HPLC.

“…The diffraction peak at 27.3 corresponds to the (002) crystal plane of the mpg-C 3 N 4 thin layer. 21 Aer compounding with polyanions, the peaks shi slightly. This is because the electrostatic attraction and hydrogen bonding between multiple acids and mpg-C 3 N 4 reduces the spacing between the layers of C 3 N 4 , indicating that multiple acids have compounded to the surface of C 3 N 4 .…”
