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.

“…However, basic catalysts such as metal oxides still show higher performance or activity than solid acid catalysts [17]. Several types of solid oxide catalysts that have been used include CaO [18], MgO [19], SrO [20], ZnO [21], PbO [22], and zirconium oxide [23]. Therefore, a combination of a solid acid catalyst such as zeolite coupled with metal oxides will provide a higher conversion of biodiesel products at lower relative temperatures [24].…”

The conversion of biodiesel from rubber seed oil has been carried out using heterogeneous catalyst based on natural zeolite. The methods used include activated and calcined to produce active natural zeolite (ZAA). ZAA are embodied metal oxides of PbO, ZnO, and ZrO 2 through wet impregnation to produce bifunctional catalyst. The catalysts activity test was carried out in biodiesel synthesis at temperature 60ºC for 60 minutes with 5%(w/w) catalysts. Crystallinity of catalysts increased after the activation process and ZrO 2 loaded but decreased after PbO and ZnO loaded. The catalyst components after modification decreased Al levels due to dealumination process as well as reduced impurities. Spesific surface area of catalysts decreased after impregnation while total pore volume increased. Metal oxides loaded has an effect in increasing biodiesel conversion and reducing FFA content. The best performance was shown by ZrO 2 /ZAA catalysts with yield conversion of 58.10% and FFA conversion to methyl ester reaches 86.22%. The characteristics of water content, FFA content, and density of 0.092%, 1.081%, and 0.880 g/cm 3 , respectively. These data showed that biodiesel from rubber seed oil which was catalyzed by a bifunctional catalyst has the potential to be developed as an alternative source of future renewable and environmentally friendly fuels.

“…Heterostructure, oxygen defect, and crystallinity were closely related to the photocatalytic phenomenon and the presence of metallic AgNP and oxygen vacancy on the surface of ZnO nanorods increased the distance of photogenerated electronhole pairs, enhancing the photocatalytic activity [16,17]. The use of Ag and ZnO to prepare a composite particle could solve many optoelectronic to biomedical problems because Agincorporated ZnO is a better photocatalyst [18] and antimicrobial agent [19].…”

A silver/zinc oxide nanocomposite (Ag/ZnONC) was synthesized using the aqueous leaf extract of Atalantia monophylla as a reducing and capping agent, under controlled and effective microwave heating with silver nitrate (AgNO 3 ) and zinc nitrate hexahydrate (ZnNO 3 Á6H 2 O) serving as precursor salts. The X-ray diffraction spectra peak and selective area electron diffraction patterns confirmed the crystalline nature of the synthesized nanocomposite particles. High-resolution scanning electron microscopy images and high-resolution transmission electron microscopy micrographs of Ag/ZnONC showed an aggregated net-like structure containing small spherical Ag nanoparticles (AgNPs) supported by the large aggregated ZnO nanoparticles (ZnONPs). The eco-friendly synthesized Ag/ZnONC shows great relevance in areas like photonics, catalysis, electronics, and biomedicals.
