“…Figure 2a confirmed that g-C 3 N 4 displayed a 2D laminated structure, which is similar to its graphite analogue, containing several stacking layers [38]. As shown in Figure 2b,c, pure CuO showed a dense agglomeration of rough nanoscale rods and spherical particles with an average diameter of 5–10 nm.…”

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.

“…To date, various methods have been developed to modify nanosized TiO 2 , such as physical methods [4,5], metals doped [6,10] and sensitization modified [3,7]. Among these methods, the sensitization method can effectively extend the range of visible light absorption, and improve the photocatalytic efficiency for TiO 2 [7,8].…”

A new and sustainable process was reported for the in situ synthesis of Nb‐Pb co‐doped and Pd‐loaded TiO2/BaTiO3 nanometer heterostructures from waste multilayer ceramic capacitors through a simple chlorination–leaching route. The particle size of the Nb‐Pb co‐doped heterostructure and the Pd loading were 20–50 nm and less than 5 nm, respectively. The bandgaps of the prepared samples were in the range 2.81–2.92 eV. The optimal simulated‐sunlight photocatalytic H2 production rate and Rhodamine B degradation rate of the prepared heterostructure could reach 576.8 μmol g−1 h−1 and 0.29911 min−1, respectively, which were approximately 11.3 and 19.1 times higher than those of commercial TiO2, and 5.96 and 8.91 times higher than those of bare TiO2/BaTiO3. The recycled heterostructure exhibited excellent photostability and reusability. Such superior photocatalytic performance of the sample was attributed to the formation of the heterostructure, the Nb‐Pb co‐doping, and the Pd loading, which enhanced the visible light absorption and charge separation efficiency. Furthermore, DFT calculations were applied to explore the enhanced mechanism. This study demonstrates a sustainable process for the conversion of e‐waste to a high‐value‐added and highefficiency photocatalyst, which has the advantages of waste utilization, low‐cost preparation, and environmental protection.
