Nile red가 흡착된 다공성 분자체의 광촉매 활성 연구 = Photoreduction of methyl orange catalyzed by Nile red-adsorbed TiO_(2)/Y zeolites

다국어 초록 (Multilingual Abstract)

Photoreduction of Methyl Orange was investigated by using Nile Red-adsorbed TiO₂/Y zeolites. Nile Red was successfully adsorbed on TiO₂/Y zeolites and the absorption profile is very broad with maxima, ca 630 nm. The peak is largely red-shifted compared to that observed in hydrocarbon solvents. Furthermore, a broad and largely Stokes shifted emission band as observed around 660 nm. The largely Stokes shifted emission band should be originated from the excited state structural changes. In order to understand the photocatalytic activities of Nile Red-adsorbed TiO₂/Y zeolite, the photoreduction of Methyl Orange(5.0 X 10^-5 M) was studied using visible light beyond 320 nm. Methyl Orange was effectively reduced by Nile Red-adsorbed TiO₂/Y zeolite, indicating the photocatalytic activity of Nile Red-adsorbed TiO₂/Y zeolites was enhanced by about eight times higher than that of TiO₂/Y zeolite. And the photoreduction of Methyl Orange(5.0 X 10^-5 M) was studied using visible light beyond 400 nm. Methyl Orange was effectively reduced by Nile Red-adsorbed TiO₂/Y zeolite.
