LC/SnO2 fibre sheet has been prepared by filtration and solubility mechanisms through using the corn-silk fibre. The structural, morphological, optical, and electrochemical characteristics of the fabricated SnO2 nanoparticles and LC/SnO2 sheet have been analysed by XRD, SEM, FTIR, UV spectrophotometry and CV (Cyclic Voltammetry). XRD spectra of the SnO2 sample signified that the synthesized nanocrystallites belong to tetragonal structure having an average crystallite size of 30.98 nm. The SEM micrographs of LC/SnO2 sheet revealed that the nanocrystallites found to be of globular and irregular shape having granular size of 32 to 39 nm. It also indicated that the surface of LC/SnO2 sheet showed hollow-like structure having spaces and voids. The red-shifted optical bandgaps values of the SnO2 nanocrystals and LC/SnO2 sheet are 4.28 eV and 3.30 eV respectively. The electrochemical properties of the LC/SnO2 fibre-sheet and LC sheet have been analysed in the aqueous 2M electrolytic solution of KOH by using CV technique. The specific capacitances of the fabricated electrodes are found to be 5.17 μF/g and 3.66 μF/g.enSynthesis and characterization of lignocellulose/SnO2 nano-structure based flexible paper electrodes for energy storage and energy conversion applicationsThesis
