6 FAQs about [Photo-induced energy storage night light]

How do photocatalytic materials and energy storage materials work together?

It has commonly been achieved by the combination of photocatalytic materials and energy storage materials, in which energy storage materials can store the excess photogenerated carriers from photocatalytic materials in the presence of light and release these stored carriers in the absence of light ( Tatsuma et al., 2002 ).

Which energy storage material is used in photocatalysis?

To date, several energy storage material systems have been developed, such as TiO 2 -WO 3 1, 2, 3, 4, 6, 7, 8, 9, TiO 2 -MoO 3 10, Au:TiO 2 -WO 3 5, Au:TiO 2 -MoO 3 5, SrTiO 3 -WO 3 11, TiO 2 -Ni (OH) 2 12, 13 and TiO 2 -V 2 O 5 14, which have been widely used in photocatalysis, anticorrosion and sterilization in dark.

Why do photo-charged catalysts have a dark storage duration?

The dark storage duration of these photo-charged catalysts is primarily dependent on the electron release rate from the various energy storage materials. And it is influenced by the surrounding environment, involving oxygen content, humidity, and so on. The duration is speculated to be shortened when the air humidity and oxygen content increases.

Which light harvesting materials are used in solar energy storage systems?

Whereas the variety of the material system has been rapidly developed, the most frequently used light harvesting material is still TiO 2. Thus, in most energy storage systems, UV light is used for illumination. To use the solar energy more efficiently, a few visible light harvesting materials 5, 15 have been investigated recently.

How does a photocatalyst work?

Theoretically speaking, when in the presence of light with sufficient energy (hν > Eg), the conventional photocatalyst starts working to generate charge carriers for catalyzing redox reactions and at the same time the energy storage material stores the excess generated charge carriers.
