Photoinduced Simultaneous Thermal and Photocatalytic Activities of MnO 2 Revealed by Femtosecond Transient Absorption Spectroscopy

Solar light-induced catalysis has recently received great interest in efficiently and economically degrading volatile organic compounds, which deteriorate indoor and outdoor air quality. However, a few studies explored its essential photophysical and photochemical processes. Herein, the femtosecond...

Description
Summary:Solar light-induced catalysis has recently received great interest in efficiently and economically degrading volatile organic compounds, which deteriorate indoor and outdoor air quality. However, a few studies explored its essential photophysical and photochemical processes. Herein, the femtosecond transient absorption spectroscopy was used to investigate the decay of photogenerated holes in MnO with different Mn vacancies. About 67-93% of photogenerated holes recombined within a very short time (
