An in situ FT-IR study on photocatalytic reaction at semiconductor-aqueous solution interface - Mechanism of photocatalytic N-cyclization of (S)-lysine

Article abstract of DOI:10.1246/cl.1997.91

Photoinduced reaction occurring at an aqueous solution-semiconductor interface was analyzed in situ by reflection FT-IR spectroscopy. The photoinduced reflection spectral change, ΔR (= (R-R₀)/R₀), was recorded by using an IR cell consisting of a semiconductor (TiCO₂ or CdS) thin film electrode, a thin layer of aqueous (S)-lysine solution, and a calcium fluoride window. Structure of adsorbed substrate and mechanism of photoinduced reaction were discussed.
