摘要：

Hydrothermally grown tungsten trioxide coatings were prepared at 95 degrees C using differentmetal sulfates. Morphology of the oxides was altered from grains to flower- and urchin-like structures using potassium sulfate, sodium sulfate and lithium sulfate, respectively. The flower-like structures presented the highest deintercalated charge, 35 mC cm(-2) with time response of 96 s. In addition, they indicated a charge transfer resistance across the tungsten trioxide-electrolyte interface of 752 O. These outcomes imply that they are promising candidates for electroactive applications. (C) 2015 Elsevier B.V. All rights reserved.
