Photogenerated electron-hole recombination has been a bottleneck problem for photocatalytic reactions for a long time. Herein, we propose an efficient solution strategy through capturing electrons and holes with environmental factors. In this study, nanoscale iron molybdate (Fe2(MoO4)3) was successfully...

aWhen the NaF concentration increased to 1:1.2, the PL intensity of the sample S4 instead increased, inferring that the excess F ions in BiVO4 crystal lattice could act as the recombination centers of photogenerated electron–hole pairs. 当NaF集中增加到1:1.2, S4的改为增加的PL强度样品,推断...

This process is proposed to occur via trapping of photogenerated electrons in the TiO/sub 2/ by these solution species, thereby reducing the extent of deleterious electron-hole recombination. The ability of platinum deposits on TiO/sub 2/ particles to participate in electron trapping and enhance ...
aOn the basis of the above mentioned, it is an indication that an appropriate amount of F ions substituting O2 ions might effectively restrain the recombination rate of photogenerated electron–hole pairs, resulting in a decreasing of the PL intensity. 根据上述,它是暗示适当的相当数量F替代O2 ...

Electron and holeμin each layer can vary independently to account for additional recombination processes expected under illumination. Under illumination, radiative42,43,44, Auger9,45,46, and Shockley-Read-Hall47recombination take place along with photogeneration of carriers. Photogenerated hole or elect...
In general the overall efficiency of organic solar cells is influenced by four main processes; absorption (creation of bound electron-hole pairs (excitons)), charge generation (dissociation of exciton to free carriers), recombination and/or collection of carriers to their respective electrodes [1]....
We also proposed the scheme for electron–hole separation and transport at the light-driven g-C3N4/TiO2 hybrid photocatalyst interface as well as the phenol degradation mechanism under full spectrum and visible light irradiation. Highlights ► g-C3N4/TiO2 can superpose visible light response of g-...
