将酸活化的H2 +-ATP负载NiCoB非晶态合金催化剂用于糠醛选择加氢制糠醇。由于Er-ATP的二次活化作用，浸渍在H ~+-ATP上的金属离子与BH ~（4-）之间的还原过程对改性催化剂的织构性质具有重要意义。H+-ATP与NiCoB颗粒相互作用的增强促进了NiCoB非晶合金的分散。在最佳反应条件下（140 ℃，3 MPa H_2，800 rpm，NiCoB活性组分占FUR的3.8wt%），FUR转化率为91.3%，FA选择性为82.0%。催化剂循环使用6次后，FUR转化率提高了3.9%，FA选择性提高了8.2%，这可能是由于新生成的Co-Ni合金活性中心的作用。H+-ATP的低成本性质使得负载型NiCoB催化剂成为工业生产FA的潜在催化剂。
Acid-activated attapulgite (H+-ATP)-supported NiCoB amorphous alloy catalysts were applied to the selective hydrogenation of furfural (FUR) to furfuryl alcohol (FA). The reduction process between metallic ions impregnated in/on H+-ATP and BH4- is important to modify the textural properties of catalyst, because of the secondary activation of Er-ATP. The enhancement of interaction between H+-ATP and NiCoB particles promotes the dispersion of NiCoB amorphous alloy. Under the optimal conditions (140 degrees C, 3 MPa H-2, 800 rpm, 3.8 wt % of NiCoB active component with respect to FUR), FUR conversion of 91.3%, and FA selectivity of 82.0% were achieved over the best catalyst (20%NiCoB/H+-ATP). Moreover, the catalyst was recycled six times and showed an increase of 3.9% in FUR conversion and 8.2% in FA selectivity, which might be due to the newly generated Co-Ni alloy active site. The low-cost nature of H+-ATP makes the supported NiCoB catalyst a potential catalyst for the industrial production of FA.
