ZrO₂, Al₂O₃ and ZrO₂/Al₂O₃ with different Zr/Al molar ratio, have been synthesized by coprecipitation and subsequent calcination. The resulting catalysts were characterized by X-ray diffraction, transmission electron microscopy, N₂ adsorption-desorption at -196 °C, CO₂-thermoprogrammed desorption, NH₃-thermoprogrammed desorption and X-ray photoelectron spectroscopy. Then, the catalysts were evaluated in the Meenwein-Ponndorf-Verley reduction of furfural (FUR) using 2-propanol as sacrificing alcohol. The catalyst with a Zr/Al molar ratio of 1, Zr₅Al₅, reached the highest conversion value at shorter reaction times, attaining a FUR conversion of 95 % with a yield of furfuryl alcohol (FOL) above 90 % after 5 h of reaction at 130 °C, due to its greater amount of acid sites, as well as higher specific surface area and pore volume.

通过共沉淀和随后的煅烧合成了具有不同Zr / Al摩尔比的ZrO ₂，Al ₂ O ₃和ZrO ₂ / Al ₂ O ₃。通过X射线衍射，透射电子显微镜，-196℃下的N ₂吸附-脱附，CO _2-热程序解吸，NH _3-热程序解吸和X射线光电子能谱表征所得催化剂。然后，使用2-丙醇作为牺牲醇，通过Meenwein-Ponndorf-Verley糠醛还原（FUR）评估催化剂。Zr / Al摩尔比为1，Zr ₅ Al ₅的催化剂在130°C下反应5小时后，在更短的反应时间内达到了最高的转化率值，FUR转化率达到95％，糠醇（FOL）的收率超过90％，原因是以及更高的比表面积和孔体积。
