“…MWCNTs are made up of many nested layers of very well concentrically arranged rolled graphite sheets (Zhao et al 2016). Chemical functionalization, by the way of a functional group addition (Fiyadh et al 2019), of the surfaces of MCNTs is also a growing area of research because of the improved properties and capabilities of the resulting structure (Elias et al 2017;Moradi et al 2017). The surfaces of the CNTs can be tuned and engineered through the incorporation of specific heteroatoms to enhance the surface wettability and improve adsorption capacities for certain types of compounds (Patiño et al 2015).…”

Textile wastewaters contain refractory dyes that cause pollution and socioeconomic issues, thus calling for efficient remediation techniques such as photocatalysis. We review the fabrication, functionalization, performance and limitations of doped catalysts for degrading and mineralizing dyes. We present developments in photocatalyst immobilization and photocatalytic reactor design. Methods such as microwave irradiation, sonication and use of ionic liquids are emerging for the preparation of doped photocatalysts. Whilst single-dye systems have been extensively studied, there is limited knowledge on multipledye systems. Immobilization of photocatalysts is gaining popularity for large-scale application, but faces issues of erosion, corrosion, mechanical strength and structure integrity. Ecotoxicological studies are required in real environments to validate the potential applications of nanostructured doped photocatalysts.

“…Figure 4 shows the UV-vis absorption spectrum of ZnO and Ce doped ZnO recorded in the 190-850 nm wavelength range. All the spectra showed the typical broad absorption of ZnO [32] . The shift in the absorption peaks lightly towards higher wavelength was observed after Ce doping.…”

Ce doped ZnO (Ce-ZnO) nano materials with different Ce molar content were prepared via chemical precipitation method. The morphology of Ce-ZnO was rod like and the size was decreased with the increase of doping amount, and the size of Ce-ZnO was 180 nm in length and 40 nm in diameter when the doping amount is 2.5%. All the samples were treated on cotton fabric, the laden fabric has excellent performance on hydrophobicity, UV resistance and antibacterial activity. The contact angle of fabric loaded with ZnO was 103°, and fabric with 2.5% Ce-ZnO was 148°. The fabric loaded with Ce-ZnO has superior performance of UV resistance. With the increase of doping amount, the antibacterial rates were promoted and then reduced, the antibacterial rates against S. aureus and C. albicans of fabric with 2.5% Ce-ZnO were promoted to 83% and 85%, however, the antibacterial activity against E. coil was reduced to 78%.

Zinc oxide (ZnO) is a multifunctional material due to its exceptional physicochemical properties and broad usefulness. The special properties resulting from the reduction of the material size from the macro scale to the nano scale has made the application of ZnO nanomaterials (ZnO NMs) more popular in numerous consumer products. In recent years, particular attention has been drawn to the development of various methods of ZnO NMs synthesis, which above all meet the requirements of the green chemistry approach. The application of the microwave heating technology when obtaining ZnO NMs enables the development of new methods of syntheses, which are characterised by, among others, the possibility to control the properties, repeatability, reproducibility, short synthesis duration, low price, purity, and fulfilment of the eco-friendly approach criterion. The dynamic development of materials engineering is the reason why it is necessary to obtain ZnO NMs with strictly defined properties. The present review aims to discuss the state of the art regarding the microwave synthesis of undoped and doped ZnO NMs. The first part of the review presents the properties of ZnO and new applications of ZnO NMs. Subsequently, the properties of microwave heating are discussed and compared with conventional heating and areas of application are presented. The final part of the paper presents reactants, parameters of processes, and the morphology of products, with a division of the microwave synthesis of ZnO NMs into three primary groups, namely hydrothermal, solvothermal, and hybrid methods.
