Prospects of Emerging Engineered oxide nanomaterials and their Applications

Abstract

This review article is mainly focused the recent progress on the synthesis and characterisation of emerging artificially engineered nanostructures of oxide materials as well as their potential applications. A fundamental understanding about the state-of-the-art of the synthesis for different size, shape and morphology have been discussed in details, which can be tuned according to the desired properties of oxide nanomaterials. These tunable properties have also been discussed in details. The present review covers a wide range of artificially engineered oxide nanomaterials such as cadmium-, cupric-, nickel-, magnesium-, zinc-, titanium-, tin-, aluminium-, and vanadium-oxides and their useful applications in sensors, optical displays, nanofluids and defence.

Multiphase TiO2nanostructures: a review of efficient synthesis, growth mechanism, probing capabilities, and applications in bio-safety and health

“…Co-precipitation is also known as the wet chemical solution method and also a common method to synthesize SMONs with largely scalable production. 8,240 In the co-precipitation method, the micro-or nanostructures of multiphase TiO 2 are greatly affected by the reaction conditions, but also by the reactivity of the starting/ intermediate materials, pH value of the reaction medium and the reaction parameters, such as temperature and time. The variations mentioned above present numerous parameters to construct different high-quality nanoparticles and other nanostructures.…”

“…[1][2][3][4][5][6][7] The possible fundamental causes for this are the following: (i) interatomic interactions, (ii) cations with valence states, (iii) anions with deciencies, (iv) anisotropy and (v) high surface area-to-volume ratio. 8 Semiconductor metal oxide nanomaterials (SMONs) are amongst the most widely studied oxide materials in recent years as they have the capability to generate photo-excited electrons and holes when photons of a wavelength equal to or greater than the band gap of the SMON fall on it. 9 The noteworthy and signicant physico-chemical characteristics of SMON can be attributed to their reduction in crystal size as well as their surface structure that would substantially increase the catalysis performance and the ability to tune the band gap by possible modications of SMON, which is one of the most exciting research areas.…”

Moringa oleifera Leaf Extract-Mediated Green Synthesis of Nanostructured Alkaline Earth Oxide (MgO) and Its Physicochemical Properties

“…Metal oxides are widely employed as catalysts, optical devices, sensors, thermal conductivity enhancers, and energy conversion devices [1][2][3][4][5][6][7][8][9][10]. Engineered nanomaterials have unique properties which can be tailored with shape and size, and morphology leads to outstanding properties which are limited to bulk materials.…”

“…Engineered nanomaterials have unique properties which can be tailored with shape and size, and morphology leads to outstanding properties which are limited to bulk materials. A variety of different structured metal oxides are nanoparticles, wires, tubes, fibers, whiskers, films, layers, triangles, and tetra pods which are most desired structures widely used in technical applications, and its unique structural features are large surface-to-volume ratio, cations with valence states, anions with deficiencies, and depletion of carriers [1]. Magnesium oxides are alkaline earth-based oxide metal is attraction owing to its high economical availability, toxicity, and eco-friendly nature, has been used as inorganic phosphor for optoelectronic devices, biosensors, catalyst.…”

A review on spectral converting nanomaterials as a photoanode layer in dye‐sensitized solar cells with implementation in energy storage devices

“…As the size of materials/grains approaches to nanoscale dimensions, its physical and chemical characteristics differ significantly from that of bulk materials . It is caused due to interactions between atoms, anions with deficiencies, cations with valence states, anisotropy, and high surface/volume ratio . Depending on the orientation of nanocrystals, nanomaterials or nanostructured materials are classified in three main subclasses, within the size range of 1 to 100 nm (Figure ).…”
