چکیده انگلیسی
The uniformly flower-like WO3/CoWO4/Co nanostructures were synthesized via a facile one-step hydrothermal reaction with solid heteropolyacid of W and Co as precursors and followed by heating process and calcination under the air condition. The as-prepared WO3/CoWO4/Co composite showed a high discharge capacity of 1104Â mAhgâ1 after 40 cycles at 100Â mAgâ1, and delivered excellent rate performance of 1074, 685, 509, 335Â mAhgâ1 at 200,400,800,1600Â mAgâ1, respectively. The excellent electrochemical performance of WO3/CoWO4/Co nanostructures is attributed to the uniform dispersion of discrete nanoparticles, and it also can be highly optimized by the freestanding combination of Co-doped tungsten trioxide and cobalt tungstate, which helps to provide high specific capacity, high rate cycling and stable life performance.
