| الوصف: | The direct selective conversion of ethanol to butadiene (ETB) is a competitive and environmentally friendly process compared to the traditional crude cracking route. The acid–base properties of catalysts are crucial for the direct ETB process. Herein, we report a rationally designed multifunctional lignin-derived carbon-modulated ZnZr/SiO 2 (L-ZnZr/SiO 2 ) catalyst with suitable acid–base properties for the direct ETB reaction. A variety of characterization techniques are employed to investigate the relationship between the acid–base properties and catalytic performance of the multifunctional lignin-modulated ZnZr/SiO 2 catalysts. The results revealed that the rationally additional lignin-modulated carbon enhances both the acidity and basicity of the ZnZr/SiO 2 catalysts, providing a suitable acid–base ratio that boosts the direct ETB reactivity. Meanwhile, the 1% L-ZnZr/SiO 2 catalyst possessed ethanol conversion and butadiene selectivity as high as 98.4% and 55.5%, respectively, and exhibited excellent catalytic stability. |
