“…A small amount of cerium atoms must be introduced to the ZnS lattice structure in order for this process to take place. Through the application of this approach, researchers have seen a notable improvement in ZnS's photodegradation skills, particularly when it comes to the elimination of environmental pollutants and the purification of water [77]. In this study, when 1% cerium is doped into ZnS nanostructures, the highest photodegradation efficiency is attained.…”

Using the hydrothermal technique, we synthesised ZnS and Ce-doped ZnS nanoparticles with various doping concentrations (0.5, 1, 2.5, and 5 wt.%). X-ray diffraction (XRD) analysis indicated that pure ZnS nanoparticles exhibited a cubic phase, but when doped with Ce, the phase changed to wurtzite. The phase transition in the doped ZnS nanoparticles was also verified by Raman spectroscopy. In the photoluminescence (PL) spectra, however, no transitions matching to the dopant were identified, the overall luminous behaviour of the nanoparticles may still be influenced by the luminescence of the host material. Morphological examinations were carried out using scanning electron microscopy (SEM) and transmission electron microscopy (TEM), which revealed information about the size, shape, and distribution of the nanoparticles. The presence of Ce was further confirmed by Energy-dispersive X-ray spectroscopy (EDAX). The visible light photocatalytic activity of the nanoparticles was examined, and it was observed that the photocatalytic efficiency initially increased with doping concentration and then decreased. For 99% degradation efficiency, a doping concentration of 1% was determined to be optimal. The success of the synthesis and characterisation of Ce-doped ZnS nanoparticles is highlighted in this work, which demonstrates their phase change, shape, elemental composition, and photocatalytic activity. the findings give important insights into the possible uses of these nanoparticles in photocatalysis and other domains like optoelectronics.

“…In addition, due to the Ce ions dimensions, a higher number of oxygen vacancies are created without modifications of the crystalline structure of the material. In their photocatalysis test, 4% Ce-doped SnO 2 attained 94.5% of efficiency on the decolouration of methyl orange, against 34.8% achieved by the undoped SnO 2 in the same conditions (100 min under UV-Vis light illumination) [83]. Song et al reported another interesting study exploring the positive effect of the vacancy defects promoted by the doping of SnO 2 with Ce ions, as depicted in Figure 7.…”

“…Furthermore, a decrease in band gap was identified and associated with superior performance in photocatalytic activity. The authors proposed that the doping prevented the recombination and allowed the effective separation/migration of photoexcited charges [83].…”

“…Some studies indicate that metal oxides themselves can release metal ions (from adsorption, dissolution, and hydrolysis processes) during antibacterial activity, which indicates that the process described above for Ag + ions can be quite common and contribute to the performance of d-SnO 2 NPs [155,162]. Baig et al have suggested that the crystallite size and the production of Sn vacancies and/or interstitial oxygen are also relevant factors in this process [83,157].…”

Nanomaterials based on metal oxides are extensively studied for several applications due to their versatility. Improvements in their performances can be obtained due to specific structural modifications. One possible modification is by doping the crystal structure, which can affect the materials structure and properties, especially in nanosized particles. Electronic features are among the properties that can be modified through the doping process, consequently morphological and optical parameters can also be controlled by this process. In this sense, this review presents some modifications to tin dioxide (SnO2), one the most studied materials, mainly through the doping process and their impact on several properties. The article starts by describing the SnO2 structural features and the computational models used to explain the role of the doping process on these features. Based on those models, some applications of doped SnO2, such as photocatalytic degradation of pollutants, CO2 reduction, and desulfurization of fossil fuels are presented and discussed. Additionally, the review describes many biological applications related to antimicrobial activity for doped SnO2 and its nanostructures. Although most of the examples presented in this article are based on the doped SnO2, it also presents examples related to SnO2 composites with other nanomaterials forming heterojunctions. The metal oxides SnO2, doped-SnO2 and their nanostructures are promising materials, with results reported in many fields presented in this review, such as theoretical and computational chemistry, environmental remediation, nanoparticle morphology control, fossil fuels improvement, and biomedical applications. Although widely explored, there are still fields for innovation and advances with tin dioxide nanostructures, for example, in transparent conducting oxides, in forensics as materials for latent fingerprints visualization, and sensors in medicine for detection of exhaled volatile organic compounds. Therefore, this article aims to be a reference regarding correlating the doping processes and the properties presented by the SnO2 nanostructures.
