Biodiesel is one of the most popular biofuels as it a promising substitute for conventional diesel fuel, but now, cannot be used stand-alone fuel due to its low oxidative stability. For this reason, there have been efforts upgrade biodiesel in last few years through partial hydrogenation fatty acid methyl esters (FAMEs). This procedure succeeds resolving problem stability, some cases, new issue arises non-selective deteriorates fuel’s cold flow properties, which are crucial vehicle’s operation without damaging engine. More specifically, deteriorated properties caused by formation trans-monounsaturated and fully saturated FAMEs during reaction. Hydrogenated biodiesels preferred contain more cis-monounsaturated because these considered best combination high stability good properties. As result, various systems methods tested achieve selective FAMEs. In review article, catalytic processes that stood out research studies presented, factors lead possible outcome investigated discussed.

The present study addresses the challenges in catalytic transfer hydrogenation using methanol/ethanol for converting biomass-derived furanic aldehydes to furfuryl alcohols. introduction of air-stable Ru(II)-para-cymene catalysts with imidazole-based metal–ligand cooperativity represents a significant advancement. Spectroscopic, situ monitoring, labeling, and DFT investigations reveal mechanistic details, highlighting role Ru–H generation through dehydrogenation Ru(II)-alkoxide intermediates. Hydride proton transfers are facilitated by interconvertible coordination mode imidazole Ru(II)–para-cymene, which is crucial maintaining catalyst's efficiency selectivity. Notably, pKa N–H coordinated significantly influences reactivity, following specific order depending on attached heterocycle: > pyridine thiazole. This correlates well computed activation barrier generation. catalyst exhibits ease synthesis, stability air moisture, use renewable hydrogen sources, excellent selectivity aldehydes, applicability various potential large-scale processes. These features collectively contribute economic sustainable nature both protocol, providing valuable contribution field hydrogenation.

Selective oxidation of furfural has become important for the synthesis pharmaceutical intermediates and chemical industries. The development effective methods biomass valorization is a very attractive subject. Here, we performed an initial investigation into photocatalytic selective to maleic acid (MA) as valuable vital bioactive intermediate 5-hydroxy-2(5H)-furanone (HFO). In this work, MOFs-based Ti (NH2-MIL-125) was modified with easy method by introducing proper amount CdS (2.5%) on surface NH2-MIL-125. photocatalyst developed in work best gave high HFO (52%), MA (90%) selectivity, conversion (>90%) under various reaction conditions. (2.5%)/NH2-MIL-125 nanocomposite also showed long-term stability. Synergistic interactions between active NH2-MIL-125 (which uses organic linkers antenna) sites may result enhancement activity photocatalyst. An analysis mechanism revealed that were produced from through series multistep reactions, including oxidation, decarboxylation, ring opening.
