“…Microstructures with geometric characteristics of quadratic and hexagonal shape can be seen after enlarging the regions highlighted in figures (a) and (b), Figure 5 -c and d, respectively. The TCu morphology formed in this work showed morphological similarity with the mixed oxides of copper and titanium produced by Mahmoudabadi et al (2019) and Zeng et al (2017) (Mahmoudabadi & Eslami, 2019;Zeng et al, 2017 The EDS of Figure 6 (e) and (f) show the characteristic copper, titanium and oxygen peaks corresponding to TCu without any contamination. A variation in mass of these elements was observed, whose values are shown in Figure 5.…”

Chemical looping combustion (CLC) processes have been shown to be promising and effective in reducing CO2 production from the combustion of various fuels associated with the growing global demand for energy, as it promotes indirect fuel combustion through solid oxygen carriers (SOC). Thus, this study aims to synthesize, characterize and evaluate mixed copper and titanium oxide as a solid oxygen carrier for use in combustion processes with chemical looping. The SOC was synthesized based on stoichiometric calculations by the polymeric precursor method and characterized by: X-ray fluorescence (XRF), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM-FEG) with EDS, and Programmed Temperature Reduction (PTR). The oxygen carrying capacity (ROC) and the speed index of the reduction and oxidation cycles were evaluated by Thermogravimetric Reactivity (TGA). The main reactive phase identified was: The CuO phase for the mixed copper and titanium oxide were identified and confirmed by X-ray diffraction using the Rietveld refinement method. The reactivity of the CuO-TiO2 system was high, obtaining a CH4 conversion rate above 90% and a speed index of 40%/min. Due to the structural characteristics and the reactivity tests of this material, it is concluded that mixed copper and titanium oxide have the necessary requirements to be used in chemical looping combustion (CLC) processes.

“…Where, CuO/TiO 2 (a) was synthesized by 15min irradiation with plasma and CuO/TiO 2 (b) by 25min irradiation with plasma. Reported conversion efficiency (CE), short-circuit current density (SCCD) and open circuit voltage (OCV) for CuO/TiO 2 (a) were 7.4%, 15.38mA/cm 2 and 0.70V respectively, and for CuO/TiO 2 (b) were 9.3%, 18.80mA/cm 2 and 0.68V respectively in order to dye sensitized photovoltaic cell application [132]. Gaurav K. Upadhyay et al reported fabrication of CdO:TiO 2 by adding various volume of the precursor solutions, Where 3:2 CdO/TiO 2 showed better CE, SCC and OCV with 3.23%, 7.6mA, 0.26V values respectively for solar cell applications [133].…”

In the field of nanotechnology and nanoscience, transition metal oxides based nanocomposites (TMONCs) are promising for various application uses such as Supercapacitors, Sensors, Bactericidal properties, Photocatalytic Degradation, Solar Cells etc. Modification of transition metal oxide nanoparticles (TMONPs) to TMONCs by doping/mixing of another transition metal and metal oxide, carbon based nanoparticles, conducting polymers etc. to achieve enhanced surface area, increasing surface activities or number of active surface sites, reducing electron-hole recombination, increasing charge transfer processes etc. have been reported in literature. These improved properties are the possible reason for the enhancement in its practical applications efficiencies. This review summarizes recent development on transition metal oxides based nanocomposites for different potential applications. Also synthesis methods of transition metal oxide based nanocomposites have obtained an increasing attractions to achieve cost effectiveness and environment friendly routes of synthesis with high rate of production, high yield of product and also less toxic waste production. Transition metal oxides nanocomposites have been fabricated by various methods such as Microwave assisted synthesis technique, Sol-Gel method, Biosynthesis method, Co-precipitation process, Simple Chemical method etc. Different morphologies of transition metal oxides based nanocomposites have been summarized in this review article. Herein, this paper discuss about several reported synthesis techniques, various characterization techniques used for structural and surface properties identifications, different morphologies and various potential applications of transition metal oxide based nanocomposites.

“…Optical spectroscopy studies indicate that the PL emission properties can be adjusted by the dopant concentrations in the yttrium oxide NPs, which in turn can be controlled by the plasma process conditions. Other MONS including ZnO nanosheets, TiO 2 nanotube, europium‐doped ceria NPs CeO 2 , CuO NPs, CuO/TiO 2 nanocomposite, Ag/TiO 2 nanocomposite, SnO/GNS nanocomposite were recently synthesized using the microplasma‐assisted liquid‐phase method. These results confirm high potential of microplasmas in oxide materials processing and deposition for optoelectronics, sensing, and energy applications.…”
