本論文利用傅氏轉換紅外光譜儀(Fourier-transform infrared spectroscopy, FT-IR)研究1氫-1,2,3-三氮唑(1H-1,2,3-triazole)分子在二氧化鈦粉末表面上的吸附及反應。於真空環境中，1氫-1,2,3-三氮唑分子在150-250 oC之間三氮唑環(triazole ring)可能破裂，然後可能會以N=N-CH=CH-NH形式鍵結於TiO2表面上，當升溫超過250 oC，N=N-CH=CH-NH結構可能斷N-H鍵及C-H鍵，最後可能是以N=N-C=C-N型態鍵結於TiO2表面上。從400 oC回溫圖譜中，我們推測可能產生CH3CN、NH3及bridging η2(N,O)-CH3CONH(a)結構。於有氧環境中，除了觀察到CO2的生成外，其熱反應途徑與真空環境下類似。1氫-1,2,3-三氮唑分子在二氧化鈦上的有氧照光反應(325 nm)沒有分解反應的發生。

Fourier-transform infrared spectroscopy (FTIR) has been employed to study the thermal decomposition and photochemical reactions of 1H-1,2,3-triazole on TiO2. Under vacuum, the decomposition of 1H-1,2,3-triazole on TiO2 likely occurs between 150 oC-250 oC and leads to the formation of ring-opening intermediates such as N=N-CH=CH-NH. When the surface temperature is increased above 250 oC, N-H and C-H bonds of these intermediates may dissociate through dehydrogenation and bond breakage of C-N, C-C and N-N, finally leading to the formation of CH3CN, NH3 and bridging η2(N,O)-CH3CONH intermediate. In the presence of O2, the route of thermal decomposition of 1H-1,2,3-triazole on TiO2 was similar to that under vacuum, except for the formation of additional CO2. The TiO2-mediated photochemical reaction of 1H-1,2,3-triazole at 325 nm is negligible.
