“H₂-free” HDO is a revolutionary route to circumvent the limitations of H₂-fed HDO reactors for biomass upgrading. This work demonstrates the viability of this economically appealing route when an adequate catalyst is implemented. Herein, we have developed a new family of Pt catalysts supported on N-doped activated carbons for the H₂-free HDO process of guaiacol. Several N-donors have been used to tune the catalyst’s structural and electronic properties. As a general trend, the N-promoted samples are more selective towards oxygen-depleted products. The best performing material, namely Pt/PANI-AC, reached outstanding guaiacol conversion values – ca. 75% at 300 °C while displaying reasonable stability for multiple recycling operations. The advanced performance is ascribed to the modified electronic and acid-base properties which favor guaiacol activation and C−O cleavage, as well as the excellent dispersion of the Pt nanoparticles.

“不含H ₂ ”的HDO是一种革命性的途径，可以克服H ₂馈入的HDO反应器在生物质升级方面的局限性。这项工作证明了当使用足够的催化剂时，这种经济上有吸引力的路线的可行性。本文中，我们开发了一种新型的Pt催化剂，该催化剂负载在用于H _2的N掺杂活性炭上的愈创木酚的免费HDO过程。几个氮供体已被用来调整催化剂的结构和电子性能。通常，N促进的样品对贫氧产品更具选择性。性能最好的材料，即Pt / PANI-AC，达到了出色的愈创木酚转化率– 在300°C时达到75％，同时显示出合理的稳定性，可进行多次回收利用。先进的性能归因于改性的电子和酸碱性质，有利于愈创木酚活化和C-O裂解，以及Pt纳米粒子的出色分散性。
