Synthesis of hexagonal WO<inf>3</inf>nanowires by microwave-assisted hydrothermal method and their electrocatalytic activities for hydrogen evolution reaction

Hexagonal WO3(hex-WO3) nanowires with high aspect ratio and crystallinity have been prepared for the first time by a microwave-assisted hydrothermal method. By using X-ray diffraction, scanning electron microscopy, transmission electron microscopy and high resolution transmission electron microscopy...
