CO2和甲醇直接合成碳酸二甲酯的Fe-Zr-O催化剂制备和性能研究
Preparation and Catalytic Performance of Fe-Zr-O Catalysts for Direct Synthesis of Dimethyl Carbonate Using CO2 and Methanol
摘要
Abstract
This study investigated the preparation and catalytic performance of Fe-Zr-O catalysts prepared by co-precipitation method. The prepared catalysts were used to directly synthesize the dimethyl carbonate (DMC) from methanol and carbon dioxide. The prepared catalyst shows higher catalytic activity than catalysts prepared by other methods and it is recyclable without the decrease of activity. The synthesized catalysts were fully characterized by SEM, TEM and N2-adsorption desorption. The results reveal that they have a uniform nano-scale particle size, large specific surface area, and mesoporous channels for mass transfer. XRD and XPS results show that iron and zirconium interact with each other in the system, which increases the iron valence values and leads to the enhancement of corresponding Lewis acids. Iron and zirconium insert into their oxide lattices, which leads to the change of crystal structures of both Fe2O3 and ZrO3.关键词
