Pyrochlore Tungsten Trioxide Sensing Application

Currently, the prepared pyrochlore type tungsten trioxide (Pyrochlore-type H₂W₂O₇) is A-multi-bit deletion as the layered perovskite tissue. Pyrochlore type tungsten trioxide takes tungsten WO₆ distorted octahedral structural as motifs, it builds a layered structure having six-membered ring channels by the angle of the top of the tungsten trioxide rigid skeleton, and has a three-dimensional tunnel along the (111) direction. Pyrochlore tungsten trioxide is used in layered composite materials, sensing field, and be calcimined to prepared tungsten oxide.

Pyrochlore types of tungsten trioxide are pyrochlore type structure, it is also known as yellow-stone structure or pyrochlore structure. There will be more prominent pyrochlore out of tungsten trioxide used in the preparation of battery sensing field because it is hydrate, and its unique physical and chemical properties. Currently, it is widely used in the sensing field.

In the application process, we often make pyrochlore type tungsten trioxide in LiClO₄ electrolyte 1mol / L as the cathode, and we make lithium foil as anode, and uniformly embedding Li in the pyrochlore tungsten trioxide. Last, we have a process by ion exchange for pyrochlore type tungsten trioxide containing sodium. After testing, the result shows that the finished product has the lowest resistivity, good durability and repeatability, which can exhibits good electrochromic properties.
