광촉매(Pd/TiO_(2))에 의한 포름알데히드의 분해특성 = Decomposition Properties of Formaldehyde Gas using Photocatalyst(Pd/TiO_(2))

다국어 초록 (Multilingual Abstract)

In this paper, we propose the photocatalytic decompositon of formaldehyde gas with Pd/TiO_(2) and UV intensity 750㎼/㎤, the photocatalytic reactor was set-up in the inside of rectangular box(volume 2 ℓ), UV lamp and the coating nanofiber with Pd/TiO_(2). We investigated the reaction rate of Langmuir-Heinshelwood, conversion of formaldehyde gas on flow rate, effect of conversion under different concentration, and effect of conversion humidity level. As results, the rate constant of rate(k) and adsorption constant(β) were 114.94ppmv/min,0.0036bppm^(-1), respectively and the conversion(%) of formaldehyde gas on flow rate was decreased to 26%, comparing with the first conversion(%). The effects of conversion on formaldehyde gas concentration decreased to 51% with increased concentration and incase of conversion on humidity level, the conversion decreased with increased of humidity level the reason judged as a cause of interference factor on the decrease of contact chance with photocatalysts.
