Tungsten Oxide

The fuel cell has easily obtained raw materials, high energy density, long service life, cleaning and other advantages, as a new energy efficient conversion system. It has the potential to become one of the micro electronic components of the alternative energy.  Electrocatalysis is a key element in fuel cells. Electrocatalysts must have the following characteristics: high electrocatalytic activity, large specific surface area, good electrical conductivity, good stability and proper support. Graphene, as a typical two-dimensional material, has large specific surface area, good flexibility, and very high electron conduction rate. With the discovery of graphene and characterization of transition metal chalcogenides, same as the typical layered structure of compounds such as WS 2  exfoliatedinto research on lubricant, lithium battery, photoelectric catalysis, super capacitors and other aspects of the single or few layer structure has also made good progress. In the past, some scho...
