“…At 242 nm, absorption spectrum band is strong and prominent which can occur due to transition between valence band to conduction band and small hump is observed at 360 nm. At 360 nm, weak absorption band was expected to arise from transitions involving extrinsic states such as surface traps/defect states/impurities [28]. The intensity of the weak absorption band becomes maximum at 9 mol % and again decreases at 11…”

“…CNPs (GCR) photocatalyst displays the best performance due to the uniform structure less particle size, increase in the amount of dispersion of particles per volume, increase in number of active sites compared to other sample. Hence the particle size also plays an important role in the catalytic activity [39,40]. It was found that the photodecolorization of MG for CNPs (GCR) was 96%, whereas it was only 83% for CNPs (CCR) (Fig.…”

CuFe 2 O 4 nanoparticles (CNPs) with cubic and tetragonal spinel structures were synthesized by Jatropha oil-assisted green combustion route (GCR) and urea-assisted chemical combustion route (CCR) and well-characterized. The photocatalytic activity of CNPs prepared via GCR and CCR showed 96 and 83% sunlight degradation of Malachite green (MG) dye, respectively. Electrochemical properties of CNPs were studied by means of Cyclic Voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The current research work pledges to provide some novel insights into the design of material for multifunctional long-term applications for environmental clean-up.

“…They reported that the combustion synthesised CuO nanoparticles exhibited significant antimicrobial activity against various Gram negative ( K. Aerogenes, P. Desmolyticum and E. coli ) and Gram Positive ( S. aureus ) pathogens . Malleshappa et al., investigated the Leucas aspera leaf extract mediated combustion process for the synthesis of multifunctional CeO 2 nanoparticles. Various properties of the synthesised CeO 2 nanoparticles, which include structure, morphology, photoluminescence and photocatalytic were investigated against the concentration of LA leaf extract in the reaction mixture.…”

Metal oxide nanostructures receive great interest due to their unique size and shape dependent physicochemical and functional properties. With the rapid growth of metal oxide nanotechnology, their chemical synthesis processes have become the most promising one due to their simplicity and versatility. Among the various available chemical processes such as sol‐gel, hydrothermal, polyol and precipitation, the combustion process receives significant attention. In particular, the combustion process has been extensively explored for the synthesis of various nanostructured materials including metal oxides, which involves in the exothermic reaction upon thermal heating of precursor chemicals. Recently, the combustion process has been reinvented by using the various renewable resource‐based organic fuels, which receives increasing interest among global researchers. A wide range of plant/ leaf, fruit, flower, seed, peel, latex and tuber extracts along with the plant‐derived products have been explored in combustion process for the synthesis of various metal oxides. Hence, the present review is aimed to focus the recent advances in the combustion process by using renewable fuels for the synthesis of metal oxide nanostructures and also the emerging opportunities.
