中文摘要

背景

2,2,6,6-四甲基哌啶-氧基 (TEMPO) 與 Cu 一起已被證實是一種有前景的氧化催化工藝，可將 5-羥甲基糠醛 (HMF) 氧化為增值產品。由於 Cu-O 簇在基於 TEMPO 的 HMF 氧化中起重要作用，並且N - O部分將促進 TEMPO 再生的催化循環，因此一種有趣的固相材料，硝酸銅氫氧化物 (CNH) (Cu 2 (OH) 3 NO 3 ) 被首次提出用於共催化 TEMPO 以將 HMF 氧化成有價值的產物 2,5-二甲酰基呋喃 (DFF) 。

方法

特別是，具有二維橢圓形多孔表面的 CNH 被製造成葉狀多孔 CNH (LPCNH)，以通過相對簡單的程序最大化表面接觸，並且 LPCNH 將是具有 TEMPO 的有利催化劑，用於將 HMF 轉化為 DFF。

重要發現

雖然 TEMPO 或 LPCNH 無法將 HMF 氧化為 DFF，但 LPCNH/TEMPO 的組合可以快速有效地將 HMF 轉化為 DFF，並且具有高選擇性。在 140 °C 下，可以獲得顯著高的 Y DFF  = 99.3% 和 S DFF  = 100%，並且幾乎超過所有報導的值，表明 LPCNH+TEMPO 具有將 HMF 轉化為 DFF 的優勢和選擇性。LPCNH 也可重複使用，與 TEMPO 共催化將 HMF 轉化為 DFF。這些發現證實 LPCNH 確實是一種有用的多相催化劑，可用於使 HMF 增值。
英文摘要 Background
2,2,6,6-tetramethylpiperidin-oxyl (TEMPO) accompanied with Cu has been validated as a promising oxidative catalytic process for oxidizing 5-hydroxymethylfurfural (HMF) to value-added products. Since Cu-O cluster plays an important role in TEMPO-based HMF oxidation, and N-O moiety would facilitate the catalytic cycle of TEMPO regeneration, an interesting solid-phase material, copper nitrate hydroxide (CNH) (Cu2(OH)3NO3) is proposed for the first time for co-catalyzing TEMPO to oxidize HMF into a valuable product, 2,5-diformylfuran (DFF).
Methods
In particular, a CNH with a 2D elliptical and porous surface is fabricated to become the leaf-like porous CNH (LPCNH) to maximize surface contact via a relatively simple procedure, and LPCNH would be an advantageous catalyst with TEMPO for converting HMF into DFF.
Significant findings
While TEMPO or LPCNH was unable to oxidize HMF into DFF, the combination of LPCNH/TEMPO rapidly, and efficiently converted HMF to DFF with high selectivities. At 140 °C, a significantly high YDFF = 99.3% with SDFF = 100% can be obtained, and surpass almost all reported values, indicating that LPCNH+TEMPO is advantageous and selective to convert HMF into DFF. LPCNH could be also reusable for co-catalyzing with TEMPO for converting HMF to DFF. These findings validate that LPCNH is certainly a useful heterogeneous catalyst for valorizing HMF.
