WebMar 25, 2024 · After ultraviolet light excites TiO 2 to generate electrons and holes (stage 1), the photogenerated electrons react with O 2 molecules to form O 2 •−, while holes react with MeCN in mixed ... WebFeb 15, 2016 · The photogenerated holes in TiO2 can transfer to the NiO layer along the interface electric field under the ultraviolet irradiation. A large amount of photogenerated holes can be separated effectively and then prolonged the holes lifetime to participate in the photocatalytic oxidation reaction. The above results show that the favorable hole ...

WebThe photoinduced holes and electrons are then rapidly transferred to the interface between the photoelectrode and the electrolyte, guided by the intrinsic energy band alignment and the applied electric field [10, 11]. The photogenerated electrons trigger reduction reactions such as hydrogen evolution reaction (HER), CO 2 reduction, and N 2 ... WebMar 21, 2024 · The states of long-lived holes in the spiro-OMeTAD layers were analyzed using the simulation of the ESR spectra, which reveals the mobile photogenerated holes with a lifetime >10 μs.
