“…The Co/SBA-15 catalyst is selectively promoted the hydrogenolysis of methoxy functional group of anisole. 225 In contrast, hydrogenation of aromatic ring of anisole to methoxycyclohexane was found in the presence of Ni/SBA-15 catalyst because of high hydrogenation ability of nickel species. Yang et al 174 revealed the effect of Ce/Si molar ratio (from 0 to 0.08) on the efficiency of Ni/Ce-SBA-15 catalyst for the vapor phase HDO of anisole.…”

“…Cobalt (Co) is also one of the transition metals which has been widely studied for HDO of phenolic compounds. Co‐based catalysts exhibit higher catalytic performances compared with other transition metal, such as Ni, in terms of the production of aromatic hydrocarbons due to the high efficiency in the removal of oxygen by DDO route ,. The possible HDO mechanism of guaiacol over Co/SiO 2 catalyst is showed in Figure .…”

Catalytic hydrodeoxygenation (HDO) is a fundamental process for bio-resources upgrading to produce transportation fuels or added value chemicals. The bottleneck of this technology to be implemented at commercial scale is its dependence on high pressure hydrogen, an expensive resource which utilization also poses safety concerns. In this scenario, the development of hydrogen-free alternatives to facilitate oxygen removal in biomass derived compounds is a major challenge for catalysis science but at the same time it could revolutionize biomass processing technologies. In this review we have analysed several novel approaches, including catalytic transfer hydrogenation (CTH), combined reforming and hydrodeoxygenation, metal hydrolysis and subsequent hydrodeoxygenation along with non-thermal plasma (NTP) to avoid the supply of external H 2 . The knowledge accumulated from traditional HDO sets the grounds for catalysts and processes development among the hydrogen alternatives. In this sense, mechanistic aspects for HDO and the proposed alternatives are carefully analysed in this work. Biomass model compounds are selected aiming to provide an in-depth description of the different processes and stablish solid correlations catalysts composition-catalytic performance which can be further extrapolated to more complex biomass feedstocks. Moreover, the current challenges and research trends of novel hydrodeoxygenation strategies are also presented aiming to spark inspiration among the broad community of scientists working towards a low carbon society where bio-resources will play a major role.

“…Figure 1 displays two peaks in the range of 500-700 K, with maxima at 580 and 609 K. These two reduction peaks are widely accepted to be associated with the two reduction steps of the Co 3 O 4 spinel phase, first to the CoO phase and then to metallic cobalt (Co 3 O 4 →CoO→Co 0 ). These two reduction processes have also been described for the Co 3 O 4 phase supported on SBA-15 11,21,22 .…”
