Bulk and composite catalysts combining BEA topology and mesoporosity for the valorisation of furfural

Abstract

Synthesis strategies to materials integrating BEA topology, Zr,Al-sites and mesoporosity, for furfural valorisation via integrated reduction/acid reactions in an alcohol medium.

Advances in porous and nanoscale catalysts for viable biomass conversion

“…The combination of BEA topology, mesoporosity, and framework metal sites (Zr and Al) was demonstrated to be promising for the liquid phase catalytic conversion of furfural to useful bio-products, such as furanic ethers, levulinate esters, and angelica lactones. 158 In this work, post-synthesis acid/ alkaline/impregnation treatments were performed to introduce defect sites, mesopores, and framework Zr sites into the zeolite structures, respectively.…”

New trends in tailoring active sites in zeolite-based catalysts

“…The concentration of framework and extra-framework T catalysts for the integrated one-pot reduction and acid-catalyzed non-selective conversion of furfural to useful bio-products. [203][204][205] The incorporation of metal species in neutral (i.e. all-silica) or acidic (i.e.…”

“…Therefore, the catalytic systems based on the biphasic system that could concurrently extract HMF into an organic phase immediately after its formation in the reactive phase appeared as a more promising option [208]. Research works have proved that ionic Although furfural can be the starting block for the synthesis of a series of furan derivatives with high commercial interest [87,202], 5-hydroxymethylfurfural (HMF) is an even more attractive platform [203]. HMF ( Figure 6) is an organic product formed by the dehydration of hexoses.…”

“…However, efforts to improve the process by heterogeneous catalysis have been carried out [196][197][198][199] and the recent employment of ionic liquids as catalysts has opened a new opportunity to furfural production [200,201]. Although furfural can be the starting block for the synthesis of a series of furan derivatives with high commercial interest [87,202], 5-hydroxymethylfurfural (HMF) is an even more attractive platform [203]. HMF ( Figure 6) is an organic product formed by the dehydration of hexoses.…”
