In this work, we report the design of one-dimensional (1D) metal-organic framework containing Cu(II) and Ni(II) active sites using a ,'-bis-(4-pyridyl)isophthalamide linker to form MOF 1 [Cu(L1)(NO)·DMF] and MOF 2 [NiL1Cl]. The MOFs were evaluated as heterogeneous catalysts for the hydrogenation of furfural to furfuryl alcohol. MOF 2 catalyst showed impressive performance with conversion of FF (81%) and selectivity towards FA (100%).

- Phytomining is an innovative green technology aimed at extracting precious metals from low-grade mine tailings using bio-based catalysts.
- The study focused on a ruthenium (Ru) catalyst developed from cassava roots, which were enriched with Ru through a specialized growing process.
- Characterization techniques confirmed that the catalyst had a well-structured matrix that improved its performance, achieving 100% conversion of furfural to furfural alcohol under optimal conditions, with impressive stability over multiple uses.
A series of water-soluble Rh(i) mononuclear complexes of general formula: [Rh(sulphsal-X-R)(COD)] [sulphsal = sulphonated salicylaldimine, COD = cyclooctadiene; where R = H, Cl, CH3 and X = H, (t)Bu] have been synthesized. All the compounds were characterised using various spectroscopic and analytical techniques such as nuclear magnetic resonance spectroscopy, infrared spectroscopy, single crystal X-ray diffraction (for complex ) and mass spectrometry. All the compounds display excellent water-solubility at room temperature and were tested as catalyst precursors in the aqueous biphasic hydroformylation of 1-octene.
