Bimetallic modified Fe–Sn/Beta was synthesized and examined as a solid acid catalyst for the transformation of glucose into methyl lactate in methanol. The catalysts were characterized by a combined characterization techniques i.e. X-ray fluorescence spectroscopy, N₂ physisorption, powder X-ray diffraction, X-ray photoelectron spectroscopy, NH₃ temperature-programmed desorption, and pyridine adsorption Fourier transform infrared spectroscopy. A high yield of methyl lactate of 67% was achieved upon conversion of 0.3 g glucose in 24 g methanol over 0.15 g catalyst at 220 ℃ under 2 MPa N₂ for 6 h. The recyclability of the catalyst was also investigated, and the conversion of glucose remained constant; conversely, the yield of methyl lactate decreased slightly in five catalytic runs. The excellent catalytic performance of Fe–Sn/Beta was attributed to the presence of large amounts of Lewis acid sites. Besides, the rich mesoporosity in Fe–Sn/Beta improved mass transfer rates in the conversion of glucose to alkyl lactates.

合成并检测了双金属改性的Fe-Sn / Beta作为固体酸催化剂，可将葡萄糖在甲醇中转化为乳酸甲酯。催化剂通过组合表征技术进行表征，即X射线荧光光谱，N ₂物理吸附，粉末X射线衍射，X射线光电子能谱，NH _3程序升温脱附和吡啶吸附傅里叶变换红外光谱。在220℃和2 MPa N ₂下，在0.15 g催化剂上，将0.3 g葡萄糖在24 g甲醇中的转化率得到67％的乳酸甲酯高收率。持续6小时。还研究了催化剂的可回收性，并且葡萄糖的转化率保持恒定。相反，在五个催化过程中乳酸甲酯的产量略有下降。Fe-Sn /β的出色催化性能归因于大量路易斯酸位的存在。此外，Fe-Sn / Beta中丰富的介孔性改善了葡萄糖转化为乳酸烷基酯时的传质速率。
