Abstract:	傳統揮發性有機物（Volatile Organic Compounds，VOCs）控制技術包含了觸媒焚化法、吸收法、吸附法和冷凝法等，雖然目前已發展成熟，仍有處理成本高、能源消耗大以及產生二次污染的問題需要面對，為克服上述限制，並提升VOCs處理技術之效益，近年來發展出非熱電漿結合觸媒技術，除了將VOCs去除外，更可進一步轉化為具有附加價值之氣體，例如氫氣。本研究利用TiO2為載體，搭載Ni金屬進行觸媒催化及產氫效率測試，選擇異丙醇作為去除之目標污染物，此外，探討金屬負載量對於觸媒電漿催化之影響，控制Ni金屬負載量為1wt%、5wt%及10wt%，結果說明最佳之異丙醇去除效率條件為1wt% Ni/TiO2，在1%氧氣濃度及1%水氣下可達到84.3%的轉化率，其異丙醇電漿催化能量效率為2.49 g IPA/kWh。為了解觸媒對於本研究影響，採用X光繞射儀(XRD)及比表面積分析進行鑑定，XRD分析結果顯示，Ni成功負載於TiO2載體，而1wt% Ni/TiO2觸媒具有最佳的比表面積，達到48.9 m2/g。在產氫方面1wt% Ni/TiO2在1%氧氣濃度及1%水氣下也有最佳之產氫能量效率(0.218 g H2/kWh)，本研究在低金屬負載量下即可達到較佳之異丙醇的轉化與產氫效果，顯示其在降低VOCs排放方面深具潛力。;Traditional control technologies for volatile organic compounds (VOCs), such as catalytic combustion, absorption, adsorption, and condensation, have been well-developed. However, these methods still face challenges including high treatment costs, significant energy consumption, and the generation of secondary pollution. To overcome these limitations and enhance the effectiveness of VOCs abatement, non-thermal plasma (NTP) combined with catalytic technology has recently emerged. This approach not only removes VOCs but also enables their conversion into value-added gases such as hydrogen. In this study, TiO2 supported Ni catalysts with varying metal loadings (1, 5, and 10wt%) were evaluated for isopropanol (IPA) removal and hydrogen production in a plasma catalytic system. The 1wt% Ni/TiO2 catalyst exhibited the highest IPA conversion (84.3%) and energy efficiency (2.49 g IPA/kWh) under conditions of 1% O2 and 1% H2O(g). Catalyst characterization via XRD confirmed successful Ni deposition, while BET analysis showed the 1 wt% Ni/TiO2 had the largest surface area (48.96 m2/g). This catalyst also achieved the highest hydrogen energy efficiency (0.218 g H2/kWh) under the same conditions. These results demonstrate that low Ni loading enhances both VOC conversion and hydrogen production, underscoring its potential for effective VOCs remediation.
