Hexagonal tungsten trioxide is important for preparing transparent thermal insulation material such as WO3 film and WO3 coating. Also, it is a significant anodic material of Li-ion batteries. So, WO3 is more and more well-known. Well, do you know how to prepare hexagonal tungsten trioxide? Some researchers have successfully prepared single-crystal nanowires of hexagonal tungsten trioxide (h-WO3) in a large scale by a simple hydrothermal method without any templates and catalysts. The prepared h-WO3 nanowires are uniform with diameter of…
