The main objective of this review is to provide comprehensive information about MoS2 for the researcher intended to start research on MoS2. The beginning of the review is focused on providing information on the methods, precursors, and conditions used for the synthesis of various MoS2 nanostructures such as nanospheres, nanotubes, nanoflakes, nanobelts, nanoflowers, nanofibers, nanoclusters, nanosheets, and nanowires. The structural features of MoS2, both in pure and with other composite forms, are discussed in detail using the XRD, Raman, PL and UV–visible spectra reported by various research groups. Further, the detailed morphological features of both pure and composite forms of MoS2 are also discussed by taking selected works of SEM and TEM images. Finally and very importantly, the review also summarises the multifunctional applications of the versatile MoS2 and its composites in lubricants, exploring its tribological properties, in lithium-ion batteries, revealing its electrical and electronic property, as a catalyst for water splitting hydrogen evolution reaction, oxygen evolution reactions, endorsing its potential electrochemical property, various biomedical applications such as bio sensors, bioimaging, and very importantly in environmental applications.

The effect of amount of nitrogen was investigated by further incorporating secondary nitrogen in prepared sample with urea precursor by adopting wet impregnation approach. Pure TiO2 nanoparticles were also synthesized for comparison. Prepared photo-catalysts were characterized by Fourier-Transform Infrared spectroscopy, X-Ray diffraction and diffuse reflectance spectroscopic analysis. XRD results confirmed the formation of anatase crystalline phase for all prepared samples. Laboratory test experiments on Rhodamine B (RhB) decomposition under artificial visible light (20W White LED) revealed the highest photocatalytic activity of catalyst doubly doped with ammonia solution and urea whereas pure TiO2 showed poor activity under visible light illumination. The effect of operational parameters such as catalyst dose, solution pH and substrate concentration on photocatalytic efficiency was also evaluated to obtain optimal conditions. Photocatalysis of RhB under natural sunlight with doubly-doped photo-catalyst (T5N2) showed remarkable photocatalytic performance of 99.9% after 1 hour illumination.","PeriodicalId":18235,"journal":{"name":"Materials Research Innovations","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86996124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To elucidate the effect of glycine on the adsorption capacity, the MgAl-LDH intercalated with CO3 2- anions was also prepared by urea hydrolysis method (Ur-LDH). The as-synthesised nanostructures were characterised by X-ray diffraction (XRD), Thermogravimetry/Differential Scanning Calorimetry (TG–DSC), Fourier transform infrared spectroscopy (FTIR), and Scanning Electron Microscopy (SEM), . The results demonstrated that the glycine intercalated LDH exhibited high adsorption capacity for MO dye compared with MgAl-LDH obtained by urea hydrolysis method. Adsorption isotherm data for MO adsorption on Gly-LDH at 300 K and acidic pH fitted well to the Langmuir isotherm model with a maximum adsorption capacity of 800 mg/g. l. The sorption mechanism indicates that MO molecules could be sorbed onto Gly-LDH via electrostatic attraction, and ion exchange.","PeriodicalId":18235,"journal":{"name":"Materials Research Innovations","volume":"24 1","pages":"152 - 162"},"PeriodicalIF":0.0,"publicationDate":"2022-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82784144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electronic band structure of cobalt (Co) doped GaN turns into half metallic rather than semiconducting in its pure form and reduces significantly too. The values of magnetic moment at Co and nitrogen (N) sites are 0.8 μB and 0.12 μB, respectively. The effect of the increase in Co concentration results in reduced spin-polarization and the Co magnetic moment itself. According to phenomenological band structure model, the p-d repulsion increases with increasing Co concentration, which subsequently lowers the spin-polarization and hence the d-d coupling increases due to possible charge transfer between Co t2d and ed states. The Co d-Dos diagram for various doping concentrations exhibits more broadened t2d levels, thus predicting the increase in stability with increase in dopant concentration. The coupling between Co atoms is ferromagnetic, mediated through neighboring Ga and N atoms. The absorption edge of Co-doped GaN manifests a red shift with the increase in doping concentration. These findings are in good agreement with the experimental results. We predict that a lower concentration of cobalt-doped GaN is appropriate for spintronic applications.","PeriodicalId":18235,"journal":{"name":"Materials Research Innovations","volume":"425 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76489071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
