A simple hydrothermal method was developed for the synthesis of Ag supported on α-titanium bismonohydrogen orthophosphate monohydrate, Ag@α-Ti(HPO4)2·H2O (Ag@α-TiP), using ilmenite (FeTiO3) mineral sand. The prepared nanoparticles (NPs) were characterized using powder X-ray diffraction, high-resolution transmission electron microscopy, energy-dispersive spectroscopy, X-ray photoelectron spectroscopy, and diffuse-reflectance spectroscopy. The catalytic efficiency of Ag@α-TiP NPs in the reduction of 4-nitrophenol (4-NP) to 4-aminophenol with sodium borohydride (NaBH4) in the presence/absence of ultraviolet–visible (UV–vis) radiation was examined. The reduction rate increased when Ag@α-TiP was present in the reaction mixture. The catalytic efficiency was further enhanced when the reaction mixture was exposed to UV–vis light. An ab initio molecular dynamic approach, coupled with slab model density functional theory (DFT) calculations, was used to find the optimal geometry for the model catalyst Ag4@α-TiP. The formation enthalpies and binding geometries for 4-NP and 4-nitrophenolate ion (4-NP–) on Ag4@α-TiP were calculated using DFT.

“…Many metal‐free nitrogen‐rich precursors including urea, [22,23] thiourea, [24,25] cyanamide, [26] dicyandiamide, [27,28] and melamine [29–31] are used to synthesize 2D stacked g‐C 3 N 4 . Thermal condensation under air or inert environment at 450–650 °C is most prevalent [32–34] . Nonetheless, the precursor and thermal treatment may greatly impact the obtained physicochemical characteristics of the resulting g‐C 3 N 4 , giving rise to a family of materials with customized traits such as porosity, light absorption, photoluminescence, surface charge, band gap, and so on [35–37] …”

Since their emergence in 2014, graphitic carbon nitride quantum dots (g‐C3N4 QDs) have attracted much interest from the scientific community due to their distinctive physicochemical features, including structural, morphological, electrochemical, and optoelectronic properties. Owing to their desirable characteristics, such as non‐zero band gap, ability to be chemically functionalized or doped, possessing tunable properties, outstanding dispersibility in different media, and biocompatibility, g‐C3N4 QDs have shown promise for photocatalysis, energy devices, sensing, bioimaging, solar cells, optoelectronics, among other applications. As these fields are rapidly evolving, it is very strenuous to pinpoint the emerging challenges of the g‐C3N4 QDs development and application during the last decade, mainly due to the lack of critical reviews of the innovations in the g‐C3N4 QDs synthesis pathways and domains of application. Herein, an extensive survey is conducted on the g‐C3N4 QD synthesis, characterization, and applications. Scenarios for the future development of g‐C3N4 QDs and their potential applications are highlighted and discussed in detail. The provided critical section suggests a myriad of opportunities for g‐C3N4 QDs, especially for their synthesis and functionalization, where a combination of eco‐friendly/single step synthesis and chemical modification may be used to prepare g‐C3N4 QDs with, for example, enhanced photoluminescence and production yields.

“…25,28 Overcoming these limitations involves modifying pristine g-C 3 N 4 through various approaches, such as doping with metals/non-metals/molecules/ heteroatoms, morphological and structural changes, creating defects, and constructing multiple heterostructures. 10,20,[29][30][31][32][33] Notable efforts have been made to heighten the catalytic performance of g-C 3 N 4 through heteroatom dopings such as boron (B), 34 phosphorus (P), 35 and sulfur (S), and S-g-C 3 N 4 has vastly enhanced the electronic and catalytic performances. 3,36,37 Lately, metal chalcogenides have been known to be viable catalytic candidates for their distinctive characteristics, [38][39][40][41] including catalytic 4-NP reduction 39,[42][43][44][45] due to a suitable band gap, low cost, and optimal electronic band position, and thus demonstrate excellent photo/catalytic activity.…”
