| 초록 | Surface modification of a TiO 2 photocatalyst with Ba species was investigated in photoassisted nitrogen oxide (NO x ) storage under UV-light irradiation. The NO x storage capacity in the Ba-modified TiO 2 photocatalyst was 1.4 times higher than that of the non-modified TiO 2 photocatalyst. Structure and role of the surface Ba species on a TiO 2 surface were characterized using temperature programmed reaction (TPR), diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy, X-ray diffraction (XRD), X-ray photoemission spectroscopy (XPS), and transmission electron microscopy (TEM). The characterization results suggested that Ba-Ti mixed oxides with a two-dimensional layer and amorphous structure on a TiO 2 surface were generated via decomposition of Ba(NO 3 ) 2 precursors by O 2 pretreatment at 773K. Based on the results of the characterizations and the reactions, the generated Ba-Ti mixed oxides on a TiO 2 surface stored NO x more densely than the TiO 2 surface; therefore, the generation improved the activity in the photoassisted NO x storage under UV-light irradiation. |
