In this report, molybdenum oxide (MoOx) nanomaterials are synthesized simply by a two-step thermal treatment of the prepared Mo3O10/ethylenediamine (EDA) complex precursor. The prepared MoOx nanostructures are highly crystalline and have plate- and rod-like morphologies. With increasing of the reduction temperatures, the prepared molybdenum oxide undergoes a phase conversion from MoO3 to MoO3/MoO2 and finally to MoO2. The prepared MoO2 materials are used as electrocatalysts in the hydrogen evolution reaction (HER), they can display high catalytic activity (similar to 79.35 mA/cm(2)), low Tafel slopes (similar to 87.1 mV/dec), and excellent cycling durability. It is believed that the excellent electrocatalytic performances are resulted from the high conductivity and large number of active sites on the surface of MoO2. Importantly, the facile, scalable, energy-efficient and environmentally friendly nature of the presented approach renders it particularly attractive for technology applications.
