The tunable ZnO nanorods (NRs) are produced due to the phytochemicals present in Cycas pschannae leaves which act as reducing and stabilizing agents. The confirmations of the ZnO NRs were validated using different characterization techniques: X‐ray diffraction, Fourier transform infrared spectroscopy, Brunauer, Emmett and Teller (BET), scanning electron microscopy–Energy Dispersive X‐Ray Analysis (EDX), UV–visible spectroscopy, Raman spectroscopy, and transmission electron microscopy. The ZnO NRs show unique surface area and low particle size. Photocatalytic activity was measured and found to be 50.75% at low concentrations and 78.33% at high concentrations. The antioxidant activity of the ZnO NRs also showed promising results for their use in free radical scavenging. In vitro toxicity studies using zebrafish embryos was performed to evaluate the toxic nature of it and the obtained result confirmed its non‐toxic nature. In addition, ZnO anticancer potential was verified using the A549 lung cancer cell line. Cytotoxic assessments of ZnO NRs were performed via 2,3‐bis‐(2‐methoxy‐4‐nitro‐5‐sulfophenyl)‐2H‐tetrazolium‐5‐carboxanilide (XTT), 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyl tetrazolium bromide (MTT), and neutral red uptake assays to examine the cell death cycle on the A549 lung cancer cell. Dose‐dependent apoptosis and necrosis were confirmed by Lactate dehydrogenase (LDH) assay. It was also confirmed that ZnO NRs induce Reactive oxygen species (ROS) and apoptosis inside cancer (A549) cells via different intrinsic gene expression. Thus, based on this research it is evident that an effective ecofriendly, nontoxic potential anticancer drug can be synthesized using C. pschannae leaf extract.

“…The eluent solution could be used directly for ZnO synthesis or could be dried for the concentration of solid extracts. Afterward, zinc precursors and plant extracts are reacted under various pH and temperature conditions [2]. If the extract is used as an aqueous solution, the zinc precursors are added into the solution.…”

ZnO-based nanomaterials have been proven to be of great use for several leading applications since the beginning of nanoscience due to the abundance of zinc element and the relatively easy conversion of its oxide to nanostructures. Nowadays, ZnO as nanoparticles, nanowires, nanofibers as well as plenty of other sophisticated nanostructures takes place among the pioneer nanomaterials employed in the photovoltaic systems, fuel cells, and biomedical fields. Nevertheless, optimizing energy consumption and being eco-friendly are the challenging requirements that are still to be overcome for their synthesis. Green chemistry has been strongly presented recently in the scientific arena as an adequate potential alternative; worldwide investigations have been held on subjects involving bacteria, fungus, or algae-based synthesis as efficient options, and some of the intriguing scientific findings on this subject are reported hereafter.

“…In some cases, their performance can be precisely tuned by functionalizing their surfaces with metal, metal oxides, carbon and polymeric materials . Hence, numerous physical, chemical and biological processes have been established and explored for the synthesis of various types of metal oxide nanostructures in both bottom up and top down platforms . Sputtering, laser ablation and vacuum evaporation are the few physical processes, which have been widely explored for the synthesis of metal oxide nanostructures in thin film forms .…”

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.
