Excited states in the conduction band and long-lifetime hot electrons in TiO2 nanoparticles observed with photoemission electron microscopy

The authors propose that high catalysis of TiO2 nanoparticles (NPs) originates in the generation of excited states in the conduction band, which realize a long lifetime of hot electrons. This paper confirms their claim by observing individual NPs in the femtosecond laser pump-and-probe technique usi...
