“…[ 60 ] The fast hydrolysis of Zn(Cy) 2 solubilized in various organic solvents (THF, pentane, etc.) takes place with one equivalent of water in the presence of dodecylamine (C 12 H 27 N, DDA), [ 61 ] a suitable ligand for ZnO. Note that the ligand may also play a role on the hydrolysis reaction.…”

Application of nanocomposites in daily life requires not only small nanoparticles (NPs) well dispersed in a matrix, but also a manufacturing process that is mindful of the operator and the environment. Avoiding any exposure to NPs is one such way, and direct liquid reaction-injection (DLRI) aims to fulfill this need. DLRI is based on the controlled in situ synthesis of NPs from the decomposition of suitable organometallic precursors in conditions that are compatible with a pulsed injection mode of an aerosol into a downstream process. Coupled with low-pressure plasma, DLRI produces nanocomposite with homogeneously well-dispersed small nanoparticles that in the particular case of ZnO-DLC nanocomposite exhibit unique properties. DLRI favorably compares with the direct liquid injection of ex situ formed NPs. The exothermic hydrolysis reaction of the organometallic precursor at the droplet-gas interface leads to the injection of small and highly dispersed NPs and, consequently, the deposition of fine and controlled distribution in the nanocomposite. The scope of DLRI nanosynthesis has been extended to several metal oxides such as zinc, tin, tungsten, and copper to generalize the concept. Hence, DLRI is an attractive method to synthesize, inject, and deposit nanoparticles and meets the prevention and atom economy requirements of green chemistry.

“…Other studies have compared the effect of alkylamine chain‐length on the growth of ZnO nanorods, using alkylamines such as octylamine (C8) up to oleylamine (C18). [ 46,47 ] They found that the alkylamines adsorb onto the nonpolar side facets of ZnO promoting oriented growth along the c ‐axis, similar to the behavior of other amines, with increased growth occurring more as chain length increased. This is a result of complex formation between Zn 2+ and the alkylamine, which showed increasing stability with longer carbon chains.…”

This review provides a background on the structure and properties of ZnO nanostructures. ZnO nanostructures are advantageous for many applications in sensing, photocatalysis, functional textiles, and cosmetic industries, which are described in this review. Previous work using UV Visible (UV–vis) spectroscopy and scanning electron microscopy (SEM) for ZnO nanorod growth analysis in‐solution and on a substrate for determination of optical properties and morphology is discussed, as well as their results in determining the kinetics and growth mechanisms. From this literature review, it is understood that the synthesis process greatly affects nanostructures and properties; and hence, their applications. In addition, in this review, the mechanism of ZnO nanostructure growth is unveiled, and it is shown that by having greater control over their morphology and size through such mechanistic understanding, the above‐mentioned applications can be affected. The contradictions and gaps in knowledge are summarized in order to highlight the variations in results, followed by suggestions for how to answer these gaps and future outlooks for ZnO nanostructure research.

“…As mentioned above, the organometallic precursor's character can play a significant role in the nucleation, growth and quality of the final QDs. 71,72 Diorganozinc compounds have been known to easily form the Lewis-acid adducts with lowmolecular-weight neutral donors [73][74][75][76][77] and the adduct formation strongly affects the reactivity of zinc alkyls towards water 78 and dioxygen. 76 Thus, we were curious to what extent DMF and sulfoxides as Lewis bases could be suitable candidates for tuning the reactivity of dialkylzinc compounds as auxiliary ligands.…”
