“…The catalytic hydrogenation of furfural is considered as one of the pivotal reactions to convert lignocellulose-based biomass into renewable chemicals and fuels. − Therefore, after proving the successfully preparation of Ru–MoO x /CN catalyst with well-dispersed metal particles by one-pot pyrolysis method, direct hydrogenation of FAL to THFA was chosen as a model reaction to evaluate the catalytic performance. As shown in Table , the blank run (using CN-250A-350H only) gave essentially no activity in this system after 1 h of reaction, indicating that the Ru and/or MoO x particles in the catalysts might be the active sites for this reaction.…”

A synergistic effect normally exists in bimetallic catalysts, which can greatly improve the catalytic performance in comparison with monometallic catalysts. However, the N-doped carbon-supported bimetallic catalysts, especially for noblebased bimetallic catalysts prepared by one-pot pyrolysis at high temperatures are scarcely reported. Herein, a novel sustainable Ru−MoO x bimetallic catalyst was successfully prepared by one-pot pyrolysis of biowaste (chitin) and metal salts, which exhibited great improvement in catalytic activity and could be stable up to 5 cycles for the direct hydrogenation of furfural (FAL) to tetrahydrofurfuryl alcohol (THFA). On the basis of series of catalyst characterizations, it was found that there was a strong interaction between Ru and MoO x particles, behaving as the main contributor to the enhanced catalytic performance.

“…The composition of the bimetallic catalyst determines that the main products are tetrahydrofurfuryl alcohol or the tautomeric mixtures of 5hydroxy-2-pentanone and 2-methyloxolan-2-ol. Cherkasov et al [62] synthesized a Bi-poisoned Pd catalyst (Bi isolates the Pd site by blocking the edge site primarily, altering the selectivity of the product). The results showed that at higher reaction temperature, Bi-poisoned Pd catalyst inhibited the oligomerization reaction of furfural and increased the generation of cyclopentanol.…”

Furfural is a raw material for the preparation of furan derivatives with active chemical properties. Due to its ability to prepare various high value-added chemicals through oxidation, condensation, hydrogenation, and other reactions, furfural has received extensive attention. The activity of catalyst depends largely on the solvent effect, reaction temperature, metalsupport interaction, metal nanoparticle size, and also depends on the synthesis method of catalyst. In this review, mono-metal (Cu, Co, Ni, Fe, Zn, Zr, Au, Pt, Pd, etc.) and bimetallic (CuÀ , NiÀ , PtÀ and PdÀ , etc.) catalysts supported on mesoporous silica materials for the hydrogenation of furfural to various high value-added chemicals in gas or liquid phase are highlighted. At the same time, some feasible suggestions are put forward. Mono-metal catalysts are prone to deactivation (due to carbon deposition and metal sintering), and the addition of a second metal or solvent modification can be used to improve catalyst activity, furfural conversion, and product selectivity.

“…A 5 wt % Pd/SiO 2 catalyst, poisoned by bismuth(III), was used to prepare CPN from FF in the aqueous medium. 72 Bismuth helped to isolate the active sites on the palladium surface and minimized the oligomerization of FF. As the reaction temperature was increased, the major product changed from THFAL (at 50 °C) to FAL (100–150 °C) to CPN (>150 °C).…”

Furfural (FF) and 5-(hydroxymethyl)furfural (HMF) are well-recognized biomass-derived chemical building blocks with established applications and markets for several of their derivatives. Attaining a wide spectrum of petrochemicals is the primary target of a biorefinery that employs FF and HMF as the chemical feedstock. In this regard, cyclopentanone (CPN) is a crucial petrochemical intermediate used for synthesizing a diverse range of compounds with immense commercial prospects. The hydrogenative ring rearrangement of FF to CPN in an aqueous medium under catalytic hydrogenation conditions was first reported in 2012, whereas the first report on the catalytic conversion of HMF to 3-(hydroxymethyl)cyclopentanone (HCPN) was published in 2014. Over the past decade, several investigations have been undertaken in converting FF and HMF to CPN and HCPN, respectively. The research studies aimed to improve the scalability, selectivity, environmental footprint, and cost competitiveness of the process. A blend of theoretical and experimental studies has helped to develop efficient, inexpensive, and recyclable heterogeneous catalysts that work under mild reaction conditions while providing excellent yields of CPN and HCPN. The time is ripe to consolidate the data in this area of research and analyze them rigorously in a review article. This work will assist both beginners and experts of this field in acknowledging the accomplishments to date, recognize the challenges, and strategize the way forward.
