Abstract
Here we present the first application of pore-expanded SBA-15 in heterogeneous catalysis. Pore expansion over the range 6-14 nm confers a striking activity enhancement towards fatty acid methyl ester (FAME) synthesis from triglycerides (TAG), and free fatty acid (FFA), attributed to improved mass transport and acid site accessibility.
摘要
在此，我们首次将孔扩张 SBA-15 应用于多相催化。在 6-14nm 范围内的孔扩张赋予了其对从三酸甘油酯(TAG)和游离脂肪酸(FFA)合成脂肪酸甲酯(FAME)的显著活性增强，这归因于改善了传质和酸位可及性。
