Tungsten oxide powder is a transparent thermal insulation nanopowder, which can be used in building glass to make "warm in winter and cool in summer" not a dream. And it is also energy-saving and environmentally friendly. Tungsten oxide is also a photocatalyst that can be used in photocatalytic hydrogen production, which means that the application range of tungsten oxide has been expanded.
In order to verify the photocatalytic hydrogen production performance of tungsten trioxide, researchers have applied a photochemical battery or a Z-type reaction system to apply tungsten trioxide with a conduction band position that does not satisfy the hydrogen production conditions to the application of photocatalytic hydrogen production. In addition, researchers used simple glucose hydrothermal carbonization and dialysis to prepare carbon nanodots, and added them to a solution of tungsten trioxide and NaI in a methanol aqueous solution for photocatalytic hydrogen production. They found that the amount of hydrogen the system produced has increased after the addition of tungsten trioxide.
