Oxygen vacancy formation with microwave energy in SnO2 nanowires and TEM imaging. (a) Schematic diagram showing the process of oxygen desorption and reduction to Sn on the surface of SnO2 nanowires (NWs) by microwave (MW) energy irradiation; (b–g) TEM images of SnO2 NWs (b–d) before and (e–g) after MW irradiation; (b,e) typical image of SnO2 NW; (c,f) high resolution TEM image; (d,g) SAED pattern representing single crystals. From above (b–g), the degree of oxidation on the SnO2 surface is difficult to distinguish by TEM measurement.
