Nickel(0) supported by strongly basic lanthanide hydroxides/oxyhydroxides (Ni-Ln, Ln = La, Pr, and Sm) is an efficient alternative noble metal-free catalyst for hydrogenolysis of tetrahydrofurfuryl alcohol (THFA) to 1,5-pentanediol (1,5-PeD) in organic solvents (e.g., isopropanol). The catalytic performance Ni-Ln was studied both batch continuous modes. highest yield 1,5-PeD 88% a system 73% flow using 40Ni-La reduced. Interestingly, reduced not only selective (≥84%) but also stable long-term run (386 h). It proposed that metal support interface (Ni-Ln) responsible cleaving the C–O bond THFA via two initial steps: deprotonation activation hydrogen. Additionally, transfer took place presence H2 secondary alcohols, resulting higher yields under conditions. However, addition had almost no influence on selectivity
