The low temperature method of synthesis of zinc molybdate nanostructures from oxides by hydrothermal, ultrasonic treatment, and conventional stirring was proposed. The synthesis of ZnMoO4 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 ZnMoO4 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 ZnMoO4·0.8H2O phase. DTA method showed that ZnMoO4·0.8H2O loses crystallization water in two stages up to 320 °C and ZnMoO4 was formed. All ZnMoO4 samples synthesized by alternative methods have higher SBET than ZnMoO4 synthesized by a solid-state method. It was shown by SEM and TEM that ZnMoO4 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 ZnMoO4 nanostructures at low temperature avoiding environmental pollution.
