Metal‐Loaded Metal–Organic Frameworks Catalyst Modulation for Efficient Biomass‐Derived Oxygenates Hydrodeoxygenation

ABSTRACT

Hydrodeoxygenation (HDO) is crucial for converting biomass‐derived oxygenates into valuable chemicals and fuels. Metal‐loaded metal–organic framework (Metal/MOF) catalysts, integrating the advantages of metals in activating H ₂ and C─O/C═O bonds and the properties of MOFs, such as inherent acid sites, high specific surface area, flexible and adjustable structure, have made significant progress in HDO of biomass. The activity of Metal/MOF catalysts depends on the active site and its surrounding microenvironment, and the well‐defined structure of MOFs provides an ideal platform for elucidating how these two units affect the catalytic behavior. In this review, we summarize the study of Metal/MOF catalysts in HDO of biomass‐derived oxygenates, with a focus on the synergistic effects exhibited by metals and MOFs in providing abundant active sites and flexibly modulating the microenvironment. In view of the unique structural advantages of MOFs, we present the opportunities for MOF application in HDO reactions, and propose two major strategies of defect engineering and functionalization for the design of Metal/MOF catalysts, as well as reveal the structure‐property relationship behind the enhanced catalytic performance. It is expected that this review would provide an understanding of Metal/MOF catalysts in HDO reactions and afford significant inspiration for the targeted design of HDO catalysts.
