“…As shown in Figure f (BQ for · O 2 – , AOM for h + capture, IPA for · OH capture, CCl 4 for e – capture), it can be seen from that the holes insignificantly affected the photocatalytic degradation, while the e – played a major role in the photocatalytic process. The possible mechanism for the enhancement of photocatalytic activity can be attributed to the formation of a Z‐scheme heterojunction system based on the active species trapping experiments , …”

In this work, flowerlike g-C 3 N 4 /BiOBr Z-scheme composites were constructed by a simple solvothermal method. The physical and chemical properties of the material were characterized mainly by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS), and UV/Vis diffuse reflectance spectroscopy. The photocatalytic performance of the as-prepared samples was measured by degradation of the model organic pollutant methyl orange (MO) dye and rhodamine B (RhB). The decrease [a] College

The nanostructured materials offer various advantages as they provide more flexible space for ease reconstruction, as their nanosize expands the limits and results in confinement effect, enhanced mechanical stability, and large surface area, and make them suitable for photocatalytic activities. The advancement in synthesis techniques provides the freedom to alter its physical properties as per the demand. This article provides a 360° view point on the nanomaterials which are used for solar energy harnessing with respect to environmental and energy application. The discussion emphasizes on various synthesis methods of nanostructured materials, their mechanistic features, usage in demanding applications such as photosplitting of water for hydrogen production, artificial photosynthesis, and water and wastewater treatment with an endnote highlighting the future scope of nanomaterials for real-world applications.

“…Nevertheless, the adsorption activity of pristine g‐C 3 N 4 is restricted due to its low surface area and limited functional groups. Modifying g‐C 3 N 4 to obtain composite materials is an effective strategy to circumvent these hurdles . Among the commonly investigated inorganic oxide nanomaterials, nanosized manganese dioxide (MnO 2 ) is one of the promising candidates because of its high surface area, microporous structure, good stability under acidic conditions, environmental friendliness, and a large number of surface adsorption sites .…”

A novel g‐C3N4/MnO2 composite was prepared by in situ deposition of MnO2 on graphitic carbon nitride (g‐C3N4) nanosheets, and its adsorption properties were evaluated for removal of Pb (II) in aqueous. Fourier transform‐infrared, spectrometer scanning electron microscopy and transmission electron microscopy characterization showed the g‐C3N4/MnO2 composite had a two‐dimensional/two‐dimensional (2D/2D) structure with ample active sites. The Brunauer–Emmett–Teller specific surface area of g‐C3N4/MnO2 composites (234.9 m2/g) was 13.5 times larger than that of g‐C3N4 (17.37 m2/g), providing better conditions for adsorption. The adsorption kinetic data were better fitted with the pseudo‐second‐order model. The Langmuir model was more suitable for describing the experimental equilibrium data of g‐C3N4/MnO2, and the maximum adsorption capacity was 204.1 mg/g for Pb (II). The adsorption of g‐C3N4/MnO2 composite for Pb (II) was an endothermic and spontaneous process, and reached adsorption equilibrium rapidly within initial 150 min. This composite was an excellent adsorbent because of its higher adsorption capacity and facile preparation progress.
