摘　　要：Silver molybdate(Ag_(6)Mo_(10)O_(33))exhibits excellent catalytic properties and photocatalytic degradation owing to its unique chemical and structural characteristics,but its prospective applications in electrochemistry energy storage have not received sufficient attention.Herein,the Ag_(6)Mo_(10)O_(33) meso/nanowires with superior morphological characteristics are fabricated employing a high-efficient microwave irradiation method.Furthermore,the novel synthesizing mechanism of ultralong Ag_(6)Mo_(10)O_(33) mesowires is also proved to be a“self-assembly-dissolution-recrystallization-Ostwald-ripening”process,by exploring through the parallel experiments on the dramatic alterations in topology and size of Ag_(6)Mo_(10)O_(33) at continuous reaction time.Additionally,the properties of the ultralong uniform Ag_(6)Mo_(10)O_(33) mesowires for the sodium storage are investigated via cyclic voltammetry,electrochemical impedance spectroscopy and galvanostatic charge-discharge.Notably,these as-obtained Ag_(6)Mo_(10)O_(33) mesowires exhibit an outstanding initial capacity(1587.9 mAh·g^(-1)),a remarkable specific capacity for the second cycle(817.9 mAh·g^(-1)),and an excellent reversible capacity(551.5 mAh·g^(-1) after 30 cycles).The superior electrochemical properties of the nanoscaled silver molybdate are ascribed to the lower charge transfer resistance due to the microstructure of the smallest size Ag_(6)Mo_(10)O_(33) nanosheets that exhibit a thickness of around 5 nm,which can provide a great contact with the electrolyte,facilitating the rapid diffusion of sodium ions at the electrode/electrolyte interface and the rapid transport of sodium ions within the electrode materials.Thus,the proposed synthetic strategy and achieved deep insights will stimulate the development of Ag_(6)Mo_(10)O_(33) for high-safety and long-life sodium ion batteries.
