Kinetics analysis of the electron transfer from nano-TiO2 to O2 through on-line absorptions and theoretical modeling

Baoshun Liu et al.

Summary: The electron relaxations during transfer from nano-TiO2 to O-2 were found to be slow and dispersive due to low transfer probability and multi-trapping transport. The amount of O-2 mainly affects electron transfer by changing p(tr), while light intensities and temperatures affect it by changing multi-trapping transport. The disagreement between simulations and later stage relaxations may be due to additional deep traps with a different distribution contributing to the electron relaxations.
