Metal-organic frameworks of zirconium-based and hafnium-based DUT67 were prepared through solvothermal method and using 2,5-thiophenedicarboxylate as linkers to connect metal clusters. Samples were characterized using powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and N₂ adsorption-desorption. Zr- and Hf-DUT67 were applied for catalytic transfer hydrogenation (CTH) of ethyl levulinate to selectively produce γ-valerolactone using alcohols as hydrogen donors. The effects of different alcohols, temperature and time on the reaction were studied. Hf-based DUT67 performed excellent catalytic activity in the presence of isopropanol and 2-butanol, particularly.

锆基和and基DUT67的金属有机骨架是通过溶剂热法制备的，并以2,5-噻吩二甲酸为连接金属簇的连接基。使用粉末X射线衍射（XRD），扫描电子显微镜（SEM）和N ₂吸附-脱附对样品进行表征。Zr-和Hf-DUT67用于乙酰丙酸乙酯的催化转移加氢（CTH），以醇为氢供体选择性地生产γ-戊内酯。研究了不同醇，温度和时间对反应的影响。基于的DUT67在异丙醇和2-丁醇的存在下表现出出色的催化活性。
