3 Terms and Definitions
The following terms and definitions apply to this document.
3.1 Photocatalytic water splitting reaction
Photocatalyst excited by light to generate electron-hole pairs photogenerated electrons with water or an aqueous solution of hydrogen ion reduction reaction to produce hydrogen, while
Photogenerated holes oxygenated water or sacrificial agent is consumed in the process.
3.2 Hydrogen photocatalyst
A light irradiation, can not afford to change their own, but they can promote the photocatalytic decomposition of water a chemical reaction.
3.3 Hydrogen production reaction sacrificial agent
Photocatalytic decomposition of water during the reaction, as an electron donor to restore photogenerated holes facilitate hydrogen production reaction was carried out at the same time itself does not occur
Reversible chemical conversion material is consumed.
3.4 Photocatalytic hydrogen production reaction solution
As a raw material or reactant participate Photocatalytic Hydrogen reaction and decomposition of hydrogen solution, typically water or a water-soluble sacrificial agent
Liquid, but also non-aqueous solution such as ethanolamine.
3.4.1 Inorganic sacrificial agent hydrogen reaction solution
As a sacrificial agent with inorganic photocatalytic hydrogen production reaction solution, such as sodium sulfide/sodium sulfite sacrificial agent.
