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.
“…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.…”
Solid catalysts with unique porosity and nanoscale properties play a promising role for efficient valorization of biomass into sustainable advanced fuels and chemicals.

This review discusses approaches for tailoring active sites in extra-large pore, nanocrystalline, and hierarchical zeolites and their performance in emerging catalytic applications.
“…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].

A bibliometric analysis of the Scopus database was carried out to identify the research trends related to hemicellulose valorization from 2000 to 2016. The results from the analysis revealed an increasing number of annual publications, a high degree of transdisciplinary collaboration and prolific contributions by European researchers on this topic. The importance of a holistic approach to consider the simultaneous valorization of the three main components of lignocellulosic biomass (cellulose, hemicellulose and lignin) must be highlighted. Optimal pretreatment processes are critical for the correct fractionation of the biomass and the subsequent valorization. On the one hand, biological conversion of sugars derived from hemicellulose can be employed for the production of biofuel (ethanol) or chemicals such as 2,3-butadiene, xylitol and lactic acid. On the other hand, the chemical transformation of these sugars produces furfural, 5-hydroxyfurfural and levulinic acid, which must be considered very important starting blocks for the synthesis of organic derivatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
