“…This is because each metal plays a role in the SC without dopant or composite and can attain a good specic capacitance, whereas with composites, some metals fail to show capacitance, requiring optimization for better results. N. Kumar Reddy et al 126 synthesized ower-like TiO 2 NPs from Calotropis gigantea plant leaves, which acted as catalysts, exhibiting a specic capacitance of 804 F g −1 at a current density of 1 A g −1 in 1 M Na 2 SO 4 medium. TiO 2 -doped RGO nanosheet on carbon cloth obtained from aloe vera and gram seeds exhibited a specic capacitance of 599.9 F g −1 with H 2 SO 4 as the electrolyte.…”

“…The SEM and TEM results revealed that the OTP sample had spherical-shaped grains with an average size of 100 nm, while the CGP sample had flower-like shaped grains with an average size of 200 nm. Additionally, reddy et al synthesized TiO 2 NPs using an environmentally friendly and eco-sustainable approach [62]. This approach involved the use of TiCl 4 as a precursor and the utilization of C. gigantea (CG) plant leaf extract as a catalyst.…”

The search for sustainable technology-driven advancements in material synthesis is a new norm, which ensures a low impact on the environment, production cost, and workers’ health. In this context, non-toxic, non-hazardous, and low-cost materials and their synthesis methods are integrated to compete with existing physical and chemical methods. From this perspective, titanium oxide (TiO2) is one of the fascinating materials because of its non-toxicity, biocompatibility, and potential of growing by sustainable methods. Accordingly, TiO2 is extensively used in gas-sensing devices. Yet, many TiO2 nanostructures are still synthesized with a lack of mindfulness of environmental impact and sustainable methods, which results in a serious burden on practical commercialization. This review provides a general outline of the advantages and disadvantages of conventional and sustainable methods of TiO2 preparation. Additionally, a detailed discussion on sustainable growth methods for green synthesis is included. Furthermore, gas-sensing applications and approaches to improve the key functionality of sensors, including response time, recovery time, repeatability, and stability, are discussed in detail in the latter parts of the review. At the end, a concluding discussion is included to provide guidelines for the selection of sustainable synthesis methods and techniques to improve the gas-sensing properties of TiO2.

Objectives: To investigate the electrochemical performance of TiO 2 (Titanium dioxide) nanoparticles prepared from Ocimum tenuiflorum Plant (OTP) Leaves extract. Methods : cost-effective and eco-friendly green synthesis approach is used to synthesize the TiO 2 nanoparticles. XRD (X-ray diffraction) and FESEM (Field Emission Scanning Electron Microscopy) techniques are used to analyse microstructural details. Raman and EDX (Energy Dispersive X-ray spectroscopy) are used to analyse the phase and the chemical composition of the synthesized TiO 2 nanoparticles. The nature of chemical bonding as well as the functional groups that the sample contains is identified by using FITR (Fourier Transform Infrared spectroscopy) investigation. The optical band gap of the prepared nanoparticles is estimated by UV-Vis spectroscopic analysis. Finally, Cyclic Voltammetry (CV), chronopotentiometry (CP) and electrochemical impedance spectroscopy (EIS) are used to investigate the electrochemical performance of the produced TiO 2 nanoparticles. Findings: The XRD data exhibited that the prepared TiO 2 nanoparticles are in a tetragonal structure with an anatase phase and have a crystallite size of 18.6 nm. FESEM images of the TiO 2 nanoparticles confirm the smooth surface morphology of spherical grains having an average grain size of 92 nm. The formation of the anatase phase is confirmed by the Raman spectroscopic analysis. The Ti-O-Ti bonds are identified in the sample through the FTIR absorption spectra. The optical band gap of green TiO 2 nanoparticles is found to be 3.07 eV and indexed to the anatase phase. Moreover, the better electrochemical performance of the prepared TiO 2 nanoparticles is identified from both CV and CP studies in Na 2 SO 4 aqueous electrolyte. At last, the capacitive retention attains up to 65% even after 5000 cycles for the sample prepared from OTP. Novelty: A significant component of this study is the creation of the 3D nanostructured morphology of TiO 2 nanoparticles using the green synthesis method which follows https://www.indjst.org/
