Light-induced ultrafast proton-coupled electron transfer responsible for H2 evolution on silver plasmonics
Light-driven proton-coupled electron transfer (PCET) reactions on nanoplasmonics would bring temporal control of their reactive pathways, in particular, prolong their charge separation state. Using a silver nano-hybrid plasmonic structure, we observed that optical excitation of Ag-localized surface plasmon instigated electron injection into TiO 2 conduction band and oxidation of isopropanol alcoholic functionality. Femtosecond transient infrared absorption studies show that electron transferdoi:10.1016/j.mattod.2018.05.002 fatcat:ldhlyisex5gyrl6f6ig6mjacay
