The low temperature method of synthesis of zinc molybdate nanostructures from oxides by hydrothermal, ultrasonic treatment, and conventional stirring was proposed. The synthesis of ZnMoO 4 from oxides in an aqueous medium at room temperature confirmed the thermodynamic possibility of this process. Ultrasonic or hydrothermal treatment led to an acceleration of the ZnMoO 4 synthesis process. Alternative synthesis methods and conventional co-precipitation methods from soluble salts were compared. It was shown that an alternative synthesis leads to the formation of the ZnMoO 4 ·0.8H 2 O phase. DTA method showed that ZnMoO 4 ·0.8H 2 O loses crystallization water in two stages up to 320 °C and ZnMoO 4 was formed. All ZnMoO 4 samples synthesized by alternative methods have higher S BET than ZnMoO 4 synthesized by a solid-state method. It was shown by SEM and TEM that ZnMoO 4 synthesized by hydrothermal treatment, ultrasonic treatment, and stirring have similar nanorod structure. Consequently, it was shown that the application of alternative synthesis methods allows to obtain the ZnMoO 4 nanostructures at low temperature avoiding environmental pollution.
