Spillover Hydrogen on Electron-Rich Ni/m-TiO2 for Hydrogenation of Furfural to Tetrahydrofurfuryl Alcohol

Conversion of biomass-derived furfural (FFA) platform molecule to value-added tetrahydrofurfuryl alcohol (THFA) is a sustainable route using an efficient non-noble metallic catalyst in water solvent. In this work, Ni various loadings on mesoporous titanium dioxide (m-TiO2) was synthesized one pot by Evaporation-Induced Self-Assembly (EISA). The synthesised catalysts were evaluated for the hydrogenation alcohol. characterised combination spectroscopic techniques such as XRD, H2-TPR, H2-TPD, XPS, SEM-EDX, TEM, and HR-TEM. characterization results show that Ni/m-TiO2 materials exhibit enhanced electron-rich active sites, facilitated hydrogen spillover, uniform dispersion small particles (~5 nm), strong metal support interaction between TiO2. Among dopings, 7.5 wt.% exhibited best performance achieved 99.9% FFA conversion 93.2% THFA selectivity solvent at 100 °C under 2 MPa H2. Additionally, detailed kinetic studies, process parameters, stability reusability also studied. demonstrated highly stable.
