Abstract

Photocatalytic degradation process of ATP was followed by HPLC and 1H-NMR measurements. Adenine was one of the major products when the aqueous ATP sample with TiO2 dispersion was irradiated by UV light (λ = 365 nm) for 90 min. The 1H-NMR spectra indicated the presence of another product (Z), which likely came from the ribose moiety in ATP. Photocatalytic generation of OH˙ radicals on TiO2 surface was concluded to be responsible for degrading ATP. A working hypothesis of the reaction process was proposed to account for the reaction products.
