Large-scale synthesis of WO 3 nanoplates by a microwave-hydrothermal method

Large-scale synthesis of WO 3 nanoplates by a microwave-hydrothermal method

Tungsten oxide (WO3) nanoplates were synthesized by a 270 W microwave-hydrothermal reaction of Na2WO4·2H2O and citric acid (C6H8O7· H2O) in deionized water. X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), and selected area electr...
