| 中文摘要 | 通常情況下，香草醇 (VLA) 轉化需要氧化劑（例如 H2O2）； 然而，由於化學計量化學，需要大量消耗 H2O2，並且通常需要金屬催化劑來提高 H2O2 對 VLA 的轉化率。 然而，為了追求可持續發展的目標，非常需要開發一種無氧化劑和無金屬的工藝，可以選擇性地將 VLA 氧化為香草醛 (VAE)。 本研究的目的是提出活性碳纖維 (ACF) 作為 VLA 轉化為 VAE 的高效催化劑，而無需使用金屬和氧化劑。 在 120 °C 下 30 分鐘內，ACF 可以在不使用金屬/氧化劑的情況下使 CVLA = 100% 且 SVAE = 100%。 自由基清除劑的作用和 ESR 分析進一步表明，ACF 將 VLA 氧化為 VAE 可歸因於 ACF 介導的有氧反應產生的活性氧。 |
| 英文摘要 | Typically, oxidizing agents (such as H2O2) are necessitated for vanillic alcohol (VLA) conversion; nevertheless, intensive consumption of H2O2 is required due to the stoichiometric chemistry, and metal catalysts are usually required to improve conversion of VLA by H2O2. Nevertheless, for pursuing the goal of sustainability, it would be highly desired to develop an oxidizing agent-free and metal-free process which can selectively oxidize VLA to vanillic aldehyde (VAE). The aim of this study is to propose activated carbon fiber (ACF) as a highly effective catalyst for VLA conversion to VAE without using metals and oxidizing agents. At 120 °C within 30 min, ACF could enable CVLA = 100% with SVAE = 100% without using metals/oxidants. The effect of radical scavengers and ESR analyses further reveal that the oxidation of VLA to VAE by ACF could be attributed to reactive oxygen species derived from ACF-mediated aerobic reactions. |
