Owing to the abundance of availability, low cost, and environmental‐friendliness, biomass waste could serve as a prospective renewable source for value‐added chemicals. Nevertheless, biomass conversion into chemicals is quite challenging due to the heterogeneous nature of biomass waste. Biomass‐derived chemicals are appealing sustainable solutions that can reduce the dependency on existing petroleum‐based production. Metal‐organic frameworks (MOFs)‐based catalysts and their composite materials have attracted considerable amounts of interest in biomass conversion applications recently because of their interesting physical and chemical characteristics. Due to their tunability, the catalytic activity and selectivity of MOF‐based catalyst/composite materials can be tailored by functionalizing them with a variety of functional groups to enhance biomass conversion efficiency. This review focuses on the catalytic transformation of lignocellulosic biomass into value‐added chemicals by employing MOF‐based catalyst/composite materials. The main focus is given to the production of the platform chemicals HMF and Furfural from the corresponding (hemi)cellulosic biomass, due to their versatility as intermediates for the production of various biobased chemicals and fuels. The effects of different experimental parameters on the conversion of biomass by MOF‐based catalysts are also included. Finally, current challenges and perspectives of biomass conversion into chemicals by MOF‐based catalysts are highlighted.

“…Metal-organic frameworks (MOF) are a type of crystalline porous material with periodical network structures formed by the connection of coordinate covalent bonds between organic ligands containing metal ions or metal ion clusters and oxygen or nitrogen-containing organic ligands. [16][17][18] MOF are featured by regular structures and large specific surface areas and porosity. From the aspect of materialogy, MOF have adjustable skeleton structures and functional pores.…”

Owing to the self‐reducing ability of palladium acetate in solutions, an ethanol solution containing Pd0 particles was prepared and coated in‐situ into copper metal–organic framework (Cu‐MOF), forming Pd@Cu‐MOF in a coated structure. The Pd@Cu‐MOF was reduced under N2 or H2 to form carbon‐coated Pd‐Cu@C. The pyrolysis and carbonization of Cu‐MOF and the reduction of Cu2+ were studied. The Cu‐MOF under either N2 or H2 was pyrolyzed and carbonized, but the Cu2+ reduction mechanisms were different. The high‐temperature carbothermic reduction of Cu2+ under N2 produced Cu0, but during low‐temperature reduction under H2, the reducing H2 reduced Cu2+ to Cu0. Furfural hydrogenation experiments showed that compared with H2, the Pd‐Cu@C prepared under N2 reduction displayed higher furfural hydrogenation activity. The catalytic activity of Pd‐Cu@C prepared from in‐situ Pd0 coating was higher than the Pd/Cu@C prepared from the impregnation method. With i‐propanol as the solvent, the catalytic hydrogenation of furfural under H2 consisted of direct catalytic hydrogenation with molecular hydrogen as the hydrogen source and catalytic transfer hydrogenation with i‐propanol as the hydrogen donor. The catalytic activity of direct catalytic hydrogenation is higher than the catalytic transfer hydrogenation.

Metal active sites and sufficient porosity in metal-organic frameworks (MOFs) are crucial parameters determining the performances of catalysis, guest molecule adsorption, etc. Herein, through in situ introduction of Ru sites with different levels to Cu-BTC structure together with post-synthetic activation at 180 °C, a series of hierarchically porous CuRu-BTC (HP-CuRu-BTC) MOFs were obtained. Besides, selective thermal decomposition (STD) treatment was carried out at 240 °C to further tune the hierarchical pores and metal sites, yielding rare case of metal nanoparticles (NPs)@HP-CuRu-BTC composites. After full characterization by XRD, N 2 physisorption, SEM, ICP and XPS, these HP-CuRu-BTC and NPs@HP-CuRu-BTC samples possess high surface area (682-1199 m 2 g À 1 ), hierarchical pores and highly distributed metal sites with reduced oxidation states (Cu + and Ru 2 + ), indicating regulation of both metal sites and hierarchical pores.
