  一种新型的聚对苯乙烯磺酸接枝的碳纳米管/氧化石墨烯结构，具有增强的催化性能，可合成苯甲酸酯和脂肪酸烷基酯†

  摘要：

  考虑到苯甲酸酯和脂肪酸烷基酯的合成中收率低的问题，设计高催化活性的复合催化剂是非常重要和有吸引力的。本研究采用合理的设计策略，采用简单的两步法开发了一种新型的聚对苯乙烯磺酸（PSSF）接枝的多壁碳纳米管与氧化石墨烯纳米材料（PSSF-mCNTs-GO）。FT-IR和拉曼光谱，XRD，SEM，TEM和NH 3-TPD用于表征无机-有机杂化材料。尤其是，GO的添加显着提高了其在脂肪酸烷基酯（92.16％）和苯甲酸酯（90.27％）生产中的催化性能，由于其强大的π-π相互作用，其转化率增加了一倍以上与基板。此外，PSSF-mCNTs-GO可以方便地与底物分离，即使循环使用6次后仍能保持较高的催化活性，这表明其相当可重复使用。这种新型催化剂在生物柴油和苯甲酸酯的合成中很有希望。
