This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/Molybdenum carbide catalysts supported on carbon nanofibers (β-Mo2C/CNF) were synthetized employing different carburization parameters: five temperatures (550–750 °C) and four heating rates (1–10 °C/min) were tested. The carburization process of the Mo precursor in the catalysts was studied by thermogravimetric analysis, X-ray diffraction, X-ray photoelectron spectroscopy, N2 physisorption, inductively coupled plasma optical emission spectrometry and transmission electron microscopy. The formation of the carbide phase was confirmed by the presence of the oxycarbide and carbide phases which were observed on the surface of all catalysts. Higher carburization temperatures resulted in an increase of the carbide phase content and crystal size at the expenses of the oxycarbide phase disappearance. High carburization temperatures and low heating rates were needed in order to obtain well-defined β-Mo2C crystals over the catalysts, which involved a substantial improvement of their catalytic activity in the hydrodeoxygenation of guaiacol.This work was funded by FEDER and the Spanish Economy and Competitiveness Ministry (MINECO) (ENE2014-52189-C02-01-R and ENE2017-83854-R). EO thanks for the award of her PhD under the frame of the aforementioned project. JLP thanks MINECO for his Ramon y Cajal research contract (RYC-2013-12494). The microscopy works have been conducted in the “Laboratorio de Microscopías Avanzadas” at “Instituto de Nanociencia de Aragón - Universidad de Zaragoza”. Authors acknowledge the LMA-INA for offering access to their instruments and expertise.
