Graphitic carbon nitride (g-C3N4) is a prominent semiconductor material for numerous photocatalytic applications. The mesoporous g-C3N4 (mpg-C3N4), a polymeric metal-free semiconductor proficient photocatalyst with triazine rings, is lightweight and has a high surface area. In this work, we elucidated the role of the mpg-C3N4 photocatalyst for the esterification of substituted benzaldehyde without any additives, a metal-free approach, and under visible light irradiation at room temperature. The mpg-C3N4 has been well characterized by various physicochemical techniques like X-ray diffraction, Fourier-transform infrared, UV–visible spectrophotometry, transmission electron microscopy (TEM), high-resolution TEM, elemental mapping, and the Brunauer–Emmett–Teller surface area. The catalyst characterization revealed that the as-prepared mpg-C3N4 material has a high surface area (97.39 m2/g), porosity, a medium band gap (2.83 eV), and a nanowire-like shape. The mpg-C3N4 properties enhanced the material’s photocatalytic activity toward the esterification of substituted benzaldehyde to afford a maximum of 35% conversion with 99% selectivity. A further extension of this work is explored for the organic dye degradation reaction, where it is observed that the materials are stable, sturdy, and reusable for more than eight cycles with a slight loss in activity. This research widens the versatile application of mpg-C3N4 with specific catalytic applications.

“…The existence of suitable band gap positions and inherent potential gradient at the interface of heterojunction emerged out to be responsible for the enhanced charge pair separation and transportation rate. [ 71 ] As a consequence of this, the designed MFO:SCNNS (1:1) nanocomposite heterojunction afforded superior photo‐response. Additionally, the photocatalytic degradation of Ery B and IC was also studied in the presence of the prepared MFO:CNNS (1:1) and compared.…”

“…From the industrial perspective, the recovery of the nanopowders from the treated water streams is highly desirable; thus, the use of magnetically active photocatalysts provides a convenient and cost-effective alternative. [58,71] Considering these facts, it becomes quite significant to combine the SCNNS with the magnetic material. Magnesium ferrite, MgFe 2 O 4 (MFO), a well-explored Spinel-structured ferrite, is one of the earth-abundant ferrites which has been potentially utilized as a photoactive magnetic material for environmental remediation owing to its cost-effectiveness, significant chemical and thermal strength, [72] quite lesser band gap, and extended visible light absorption ability.…”

Magnesium ferrite/sulfur‐doped graphitic nitride (MFO/SCNNS) heterostructure has been developed via sonication‐assisted deposition of zero‐dimensional MFO over the surface of two‐dimensional SCN nanosheets. Additionally, the prepared nanocomposite material has been characterized by several analytical characterization techniques including XRD, Fourier transform infrared (FT‐IR), high‐resolution transmission electron microscopy (HR‐TEM), selected‐area electron diffraction (SAED), energy‐dispersive spectrometry (EDS), Brunauer–Emmett–Teller (BET), vibrating sample magnetometer (VSM), UV–Vis. spectroscopy, electron spin resonance(ESR), and X‐ray photoelectron spectroscopy (XPS) which indicated the existence of strong interfacial interactions via heterojunction formation between MFO and SCNNS. The as prepared nanocomposite, especially MFO:SCNNS (1:1) (having 1:1 mass ratio of MFO to SCNNS), offered impressive photo‐response for the complete degradation of Erythrosine B and Indigo Carmine within 30 min under direct solar light irradiation. The enhanced photoactivity of the MFO:SCNNS (1:1) was also confirmed by the photoluminescence, photocurrent and electrochemical impedance spectroscopy. The Mott–Schottky analysis also depicts the formation of p‐n heterojunction at the interface of MFO and SCNNS, responsible for the enhanced photoactivity. Additionally, the degradation process has also been studied using mass spectrometry, UV–Vis, and ESR spectral analysis. The trapping experiments were also conducted to confirm the formation of active radical species during the photodegradation reaction. Furthermore, the nanocomposite photocatalytic material offered excellent stability and reusability and thus can serve as an effective candidate for environmental remediation application such as real waste water treatment.

Perovskite solar cells attract significant interest due to their high-power conversion efficiencies. The replacement of charge-transporting layers using inorganic materials is an effective approach for improving stability and performance, as these materials are low-cost, highly durable, and environmentally friendly. This work focuses on the inorganic hole and electron transport layers (HTL and ETL), strontium ferrite (SrFe2O4), and zinc oxide (ZnO), respectively, to enhance the efficiency of perovskite solar cells. Favorable band alignment and high charge-collection capability make these materials promising. Experimental and computational studies revealed that the power conversion efficiency of the fabricated device is 7.80% and 8.83%, respectively. Investigating electronic properties and interface charge transfer through density functional theory calculations further corroborated that SrFe2O4 is a good HTL candidate. Our numerical device modeling reveals the importance of optimizing the thickness (100 nm and 300 nm) of the HTL and perovskite layers and defect density (1016 cm−3) of the absorber to achieve better solar cell performance.
