Photocatalytic, gas-sensing and double layer capacitance properties of nanoscale SnO2 obtained from template free solution phase synthesis

A facile one-step co-precipitation approach was used in designing altered band gap energy nano SnO2 using stannous chloride dihydrate (SnCl2·2H2O) and dimethyl oxalate as precursors. Microstructure of the materials was elucidated by means of powder X-ray diffraction, selected area electron diffraction, and high-resolution transmission electron microscopy. Raman active modes at A1g + B1g + B2g + Eg indicate the tetragonal-rutile type, D4h point...
