“…The g-C3N4 material exhibited a broad peak at 2θ values of 27.8° in its X-ray diffraction (XRD) pattern. The peak at 27.8° corresponded to the (002) crystal plane of the conjugated aromatic system (JCPDS: 50-1512) [14]. It is important to note that the XRD patterns of CoWO4 and g-C3N4 were still discernible in the CoWO4/g-C3N4 composite without the decrease in intensity.…”

“…To overcome these problems, various attempt has been made to reduce the recombination of electron-hole pairs and enhance the overall efficiency of g-C3N4 including co-catalyst incorporation [11], hybridization with other materials [12], elemental doping [13], or its self-modification [14]. There has been an increasing focus on metal tungstate (MWO4) materials in recent years due to their distinct chemical and optical characteristics.…”

Methylene Blue (MB) is a common dye that has various applications in different fields, including medicine, biology, and environmental science. While it can be beneficial in certain contexts, it can also have negative effects on the environment under certain circumstances. In this study, the photodegradation of MB under visible light irradiation using a novel heterojunction CoWO4/g-C3N4 catalyst was investigated. A series of CoWO4/g-C3N4 composites were synthesized and characterized using various techniques, including XRD, SEM, SEM-EDS, FT-IR, and UV–DRS. The results revealed that the 0.3CoWO4/g-C3N4 composite showed the highest efficiency (93%) in degrading MB during the 80-minute photodegradation process, aligning with the pseudo-first-order kinetics. The results provide clear evidence that the formation of CoWO4/g-C3N4 heterojunction greatly enhances the efficiency of photocatalysis by facilitating the swift separation of electron-hole pairs and boosting the redox capability. Additionally, the photodegradation efficiency remained above 90% even after four cycles, suggesting the stability of the catalyst.

Global demand for pollution removal agents requires advanced materials to provide a good protocol to keep clean water resources. The composition of CdS was modified with ionic dopants including iron (Fe) and silver (Ag) and is incorporated into graphene oxide (GO) nanoparticles. The obtained compositions are CdS, Fe-CdS, Ag-CdS, CdS@GO, Fe-CdS@GO, and Ag-CdS@GO that have been fabricated by the co-precipitation method and examined by several techniques to estimate the morphological, optical, and structural properties using TEM, SEM, UV–Vis analysis, and XRD. The crystallite size of the CdS@Go was measured using the Williamson-Hall (W–H) method and was found to be around 28.6 nm. Furthermore, the a-axis was found to be 5.78 Å and 5.80 Å for cubic crystals and the a-axis achieved 14.28 to 14.24 Å for an orthorhombic crystal of CdS, respectively. The average roughness varied from 32.30 ± 3.3 to 66.65 ± 10.9 nm for CdS and Ag-CdS@GO. The degradation of methylene blue (MB) is increased from 75.56, 73.87, 76.01, 81.53, 89.34, and 91.68% for CdS, Fe-CdS, Ag-CdS, CdS@GO, Fe-CdS@GO, and Ag-CdS@GO after 60 min of exposure under visible light irradiation. The pseudo-first-order constant (Kapp) is increased from 4.4 × 10−3 to 39.4 × 10−3 min−1 for CdS and Ag-CdS@GO.
