Because CdO and Co form a covalent bond, Co interacts more strongly with O than Zn. In order to reduce nanoparticle crystallinity, oxygen defects improve the interaction between −O and oxygen defects in the lattice. From SEM micrographs, it appears that CdO does not completely change under the influence of dopants. It can be seen from the SEM image that both materials have very tightly packed particles. The Co and CdO dopants in ZnO nanocomposites prevent them from absorbing a large range of visible wavelengths. It is more energy-dense for nanocomposites with 5.28 eV to compare to 5.14 eV nanocomposites. The fact that CdO matrix has a tuneable bandgap is evident since different types of dopants are used in its manufacture. There are at least three distinct absorption modes in Co nanocomposites doped with CdO, around 450, 498, and 676 cm⁻¹. In addition to its absorption from 450 cm⁻¹ and 498 cm⁻¹ vibrational modes, Co-O stretching absorption along the [1<!--> <!-->0<!--> <!-->1] plane has also been observed at 676 cm⁻¹. As a method of studying charge carriers, photoluminescence spectroscopy is usually used. This method can be used to analyze electron-hole pairs (e⁻/h⁺) formed by semiconducting particles. It is in the blue emission range between the luminescence band of 615 nm and the valence band of 635 nm. With increasing cobalt and zinc concentrations, CdO nanomaterials lose their remanent magnetization. CdO has been demonstrated to have significant coercive effects in both pure and additively incorporated solutions regardless of their anisotropic, morphological, porosity, and particle size distribution. Electrochemical impedance spectrum measurements were conducted between 100 kHz and 0.01 Hz. According to the Nyquist plot, purity CdO, CdO doped Co, and CdO doped ZnO nanocomposites show a high frequency resistance to charge transfer. Nanocomposites that contained CdO doped Co &amp; ZnO were exposed to UV light for 120 min to remove the solution. The degradation of MO is virtually nonexistent when no photocatalyst is present, but with a photocatalyst, degradation can reach 92.56 %.</p></div>","PeriodicalId":18283,"journal":{"name":"Materials Science for Energy Technologies","volume":"8 ","pages":"Pages 1-12"},"PeriodicalIF":0.0,"publicationDate":"2024-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2589299124000120/pdfft?md5=c62ef97e5a210222bcdfce20ec61ed45&pid=1-s2.0-S2589299124000120-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141693506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even though it is challenging to do small-scale measurements, it is crucial to precisely gauge the thermoelectric characteristics of varying materials (organic/inorganic/MXenes). Two-dimensional materials have drawn much interest for technological applications because of their unique properties. MXenes are a class of two-dimensional (2D) transition metal carbides, nitrides, and carbonitrides that have garnered significant attention for their promising properties by showing high electrical conductivity, controllable thermal conductivity, and high Seebeck coefficient value making suitable candidates for thermoelectric energy conversion. Thermal and electrical parameters are currently measured using a variety of techniques.
