Free-polymer controlling morphology of α-MoO<inf>3</inf>nanobelts by a facile hydrothermal synthesis, their electrochemistry for hydrogen evolution reactions and optical properties
Orthorhombic molybdenum oxide (α-MoO3) nanobelts were successfully synthesized by the 100-180 °C and 2-20 h hydrothermal reactions of (NH4)6Mo7O24·4H2O solutions containing 15 ml 2 M acid (HNO3, H2SO4or HCl) with no surfactant and template adding. These products were characterized by X-ray diffracti...
