The sustainable development of energy has always been a concern. Upgrading biomass catalysis into hydrocarbon liquid fuels is one of the effective methods. In order to upgrade biomass derivative guaiacol by Hydrodeoxygenation (HDO) catalysis, this article report a three-dimensional honeycomb structure biochar loaded with Ni nanoparticles and phosphomolybdic acid demonstrating excellent catalytic performance in a short period of time. This is due to the porous structure of biochar, which allows Ni metal nanoparticles to be highly uniformly dispersed on the support, which enhances the catalytic hydrogenation of guaiacol in terms of both rate and efficiency. Furthermore, it was observed that the added phosphomolybdic acid dissolved within the temperature range of 78-90 °C, functioning as a homogeneous catalyst in the process. This proves advantageous, as the phosphomolybdic acid becomes accessible at any location within the porous Ni/C catalyst. The detailed characterization data revealed that the carbon support prepared in this study has a high specific surface area of up to 1375.61 m/g. Additionally, the phosphomolybdic acid exhibited rich acidity, with Brønsted and Lewis acid contents of 2.55 μmol/g and 21.45 μmol/g, respectively. Reaction data demonstrated that at 240 °C for 180 min, 100 % conversion and 97.9 % cyclohexane selectivity were achieved. This study introduces a bifunctional catalyst with an unique catalyst's structure, facilitating a heterogeneous-homogeneous catalytic reaction and delivering an efficient catalytic effect.
能源的可持续发展一直是人们关注的焦点。将生物质催化升级为烃类液体燃料是有效方法之一。为了通过加氢脱氧（HDO）催化升级生物质衍生物愈创木酚，本文报道了一种负载镍纳米颗粒和磷钼酸的三维蜂窝结构生物炭，其在短时间内展现出优异的催化性能。这归因于生物炭的多孔结构，它能使镍金属纳米颗粒高度均匀地分散在载体上，在速率和效率方面都增强了愈创木酚的催化加氢效果。此外，观察到添加的磷钼酸在78 - 90 °C的温度范围内溶解，在该过程中作为均相催化剂发挥作用。这被证明是有利的，因为磷钼酸在多孔Ni/C催化剂内的任何位置都可发挥作用。详细的表征数据显示，本研究制备的碳载体具有高达1375.61 m/g的高比表面积。此外，磷钼酸表现出丰富的酸性，布朗斯特酸和路易斯酸含量分别为2.55 μmol/g和21.45 μmol/g。反应数据表明，在240 °C下反应180 min，愈创木酚的转化率达到100 %，环己烷选择性达到97.9 %。本研究引入了一种具有独特催化剂结构的双功能催化剂，促进了多相 - 均相催化反应并产生高效的催化效果。
