“…The catalytic activity of commercial niobium oxide catalyst (Nb2O5 from CBMM) was also evaluated as a reference. Niobium oxide possessed poor activity (21 mol g -1 h -1 ) in the studied reactions, reaching a conversion of only 15% after 8 h, in agreement with previous reports in the literature [51]. In general, from the comparison with data from TableS.1, Nb-MXenes emerge as highly active catalysts with superior activity compared to most noble metal-free catalysts already proposed in the literature.…”

“…Recently, niobium oxide modified by incorporation of dopants (W 6+ and Ti 4+ ) has been successfully employed as support in Pt-based catalysts for furfural hydrogenation, unveiling the crucial role of support Lewis acidity in diverting the reaction selectivity. [51] Starting from these considerations, in this work multilayered Nb2CTx and Nb4C3Tx MXenes were evaluated as catalysts for the catalytic transfer hydrogenation (CTH) of furfural using 2-propanol as the hydrogen source. In general, to the best of our knowledge, this is the first study reporting the use of Nb-carbides as catalysts in hydrogenation reactions of organic substrates.…”

This account celebrates the long and successful scientific career of Laura Prati, recalling her most important scientific achievements since the beginning of her work as a researcher in inorganic chemistry. Laura went through many aspects of liquid-phase heterogeneous catalysis, taking her first steps in the field of catalysts synthesis, where she pursued the development of innovative strategies for preparing catalysts until laying the foundations of the colloidal synthesis of metal nanoparticles, with particular interest in gold. Her investigations in colloids for catalysis had a natural outcome on catalysts synthesis and optimization. In her career, she dealt with liquidphase oxidation reactions, with particular attention to biomass valorization processes. According to this, she could not help to deal also with hydrogenation and hydrogenolysis reactions, to which she dedicated herself, especially in the more recent years. Her discoveries have influenced many researchers in the area of heterogeneous catalysis and design of materials.

“…Knowing that supported acid-materials are suitable choices for furfural hydrogenation reaction, Jouve and coworkers [57] prepared Pt catalysts supported on niobia, producing bifunctional catalyst, and modified the acidity of this oxide by incorporation of dopants (W 6+ and Ti 4+ ). The incorporation of theses cations induced alterations in the surface acidity of the support, mainly modifying the Lewis acid sites.…”

Energy and the environment will always play key roles in society. The climate emergency cannot be ruled out to enable the transition for a clean energy future. Currently, non-renewable energy resources are declining, therefore is important to continuously explore renewable resources. Biomass is a renewable resource that can be applied to reduce climate changes and to accomplhish emission policies. Cellulose is the most abundant type of biomass worldwide, which can be transformed into biofuels and potential building block platform molecules (e.g furfural) throughout biological or chemical methods. Furfural can be synthetized from cellulose using hydrolysis and dehydration reactions. Furfural has a furan ring and carbonyl functional group which makes it an important intermediary to produce higher value-added molecules at industrial level. These molecules include gasoline, diesel and jet fuel. However, furfural can also be transformed by hydrogenation, oxidation, decarboxylation and condensation reactions. The selective hydrogenation of furfural produces furfuryl alcohol, an important industrial compound, which is widely employed in the production of resins, fibers, and is considered an essential product for pharmaceutical applications. On the other hand, the oxidation of furfural produces furoic acid which is appliedin the agrochemical industry, where it is commonly transformed to furoyl chloride which is finally used in the production of drugs and insecticides. The oxidation and reduction of furfural can carry out through heterogeneous and homogeneous catalysis, and biocatalysis. Selectivity is an important issue in furfural hydrogenation and oxidation reactions since different products can be obtained by using monometallic or bimetallic catalysts and/or different catalyst supports. In biocatalysis approach, different enzymes, complete cells, tools of modern biotechnology, DNA sequencing, regulation of metabolic networks, overexpression of genes that encode enzymes of interest and optimization of the cellular properties of the microorganism are used. Herein, a review on the current status of furfuryl alcohol and furoic acid production from furfural by heterogeneous catalysis and biocatalysis has been studied. The stability, selectivity and activity of catalystsalong with the different furfural oxidation and reduction conditions have been pointed out. Additionally, the main enzymes, microorganisms and mechanism involved in the furfural degradation process have also been discussed.
