Carbon nanotubes-supported Ni catalysts were investigated for the hydrogenation of furfural as a biomass-derived furanic model compound at the liquid-liquid interface of Pickering emulsions in a batch reactor at 200 °C and 2.0 MPa of H₂ pressure. The catalysts were characterized by N₂ physisorption, He-TPD/MS, NH₃-TPD/MS, TEM, CO chemisorption, H₂-TPR, contact angle and optical/fluorescent microscopy. It was found that an increase of surface oxygen groups allows for the formation of amphiphilic particles. The amphiphilic 10%Ni/CNTox particles were homogeneous dispersed at the water-oil interface of the emulsion droplets thus enhancing the catalytic activity in furfural conversion.

研究了碳纳米管负载的Ni催化剂在分批反应器中于200℃和2.0 MPa的H ₂压力下在Pickering乳液的液-液界面处氢化糠醛作为生物质衍生的呋喃模型化合物。通过N ₂物理吸附，He-TPD / MS，NH ₃ -TPD / MS，TEM，CO化学吸附，H ₂ -TPR，接触角和光学/荧光显微镜对催化剂进行表征。发现表面氧基团的增加允许两亲粒子的形成。两亲性的10％Ni / CNTox颗粒均匀分散在乳液小滴的水-油界面处，从而提高了糠醛转化的催化活性。
