“…The catalytic performance of the Ni x MoCN catalysts was investigated in the deoxygenation of MPA, one of the typical bio-oil platform molecules at 0.1 MPa and 300 °C. ,,, The product distribution is described directly in Figure and Figure S4. It is clear to find that the kinds of products are similar, which consist of pentadecane, pentadecene, hexadecane, hexadecane, hexadecenal, hexadecanol, palmitic acid, and palmityl palmitate.…”

“…However, the high content of oxygen in biomass as the dominating stumbling block has severely restricted its wide utilization. , One of the sensible and acknowledged ways to accomplish the oxygen removal in biomass is via a hydrotreating process. As a typical triglyceride-based material, fatty acid methyl ester has been widely applied to the study of production of bio-fuels. − Thereinto, exploration of hydrotreating catalysts is of great interest for the deoxygenation process. Generally speaking, two kinds of catalysts, namely, sulfided transition metals (such as sulfided NiMo or CoMo) and supported noble metals like Pt/Al 2 O 3 , Pd/ZSM-22/SiO 2 , and Rh/ZrO 2 exist that are used in the update of fatty acidic esters. ,− The supported noble metals suffer from difficulties like rare reserves and high prices .…”

The rational exploit of fatty esters to obtain clean fuels can effectively solve the problems of energy depletion and carbon emission. The challenges are the optimal catalytic process and the development of highly efficient catalysts for the removal of oxygen from fatty esters in bioenergy. Herein, nickel molybdenum carbonitride (Ni x MoCN) nanostructures with low cost and Pt-like properties are simply obtained from one-step pyrolysis of a self-assembly NiMo-based organic–inorganic precursor and tested in the deoxygenation of methyl palmitate. The introduced Ni plays a great role in the phase composition and catalytic properties of Ni x MoCN with steerable nanoheterostructures. Regioselectivity cleavage of C–O and C–C bonds exists over Ni x MoCN nanocatalysts. The optimal Ni0.30MoCN with 49% β-Mo2C and 51% Ni2Mo3N shows 98.3% conversion and 100% deoxygenation degree, which are much higher than those of MoCN with a β-Mo2C phase (only 12.4% conversion and 51% deoxygenation degree at a contact time 0.35 min under 300 °C and 0.1 MPa). The main reaction route over the MoCN nanocatalyst is hydrodeoxygenation of methyl palmitate, while the hydrodeoxygenation and decarbonylation/decarboxylation of methyl palmitate compete over the Ni0.30MoCN nanocatalyst.

The transformation of renewable bio‐oil into platform chemicals and bio‐oil through catalytic processes embodies an efficient approach within the realm of advancing sustainable energy. Spinel‐based catalysts have garnered significant attention owing to their ability to precisely tune metals within the framework, facilitating adjustments to structural, physical, and electronic properties, coupled with their remarkable thermal stability. This review aims to provide a comprehensive overview of recent advancements in spinel‐based catalysts for upgrading bio‐oil. Its objective is to shed light on their potential to address the limitations of conventional catalysts. Initially, a comprehensive analysis is conducted on different metal oxide composites in terms of their similarity and dissimilarity on properties. Subsequently, the synthesis methodologies are scrutinised and potential avenues for their modification are explored. Following this, an in‐depth discussion ensues regarding the spinels as catalysts or catalyst precursors for catalytic cracking, ketonisation, catalytic hydrodeoxygenation, steam and aqueous‐phase reforming, and electrocatalytic upgrading of bio‐oil. Finally, the challenges and potential prospects are addressed, with a specific focus on the machine learning – based approaches to optimise the structure and activity of spinel catalysts. This review aims to provide specific directions for further exploration and maximisation of the spinel catalysts in the bio‐oil upgrading field.
