Catalysts were synthesized via a hydrothermal method at 150 °C for 24 h, followed by H 2 reduction at 450 °C for 1.5 h. X-ray Diffraction (XRD) analysis showed that the formation of Ni-Co alloy phase at 2θ = 44.2° for Ni-Co(3.0)/TiO 2 and Ni-Fe alloy at 2θ = 44.1° for Ni-Fe(3.0)/TiO 2 . The amount of acid sites was measured by using ammonia-temperature programmed desorption (NH 3 -TPD). Ni-Co(3.0)/TiO 2 has three NH 3 desorption peaks at 180 °C, 353 °C, and 569 °C with acid site amounts of 1.30 µmol.g - 1 , 1.0 µmol.g - 1 , and 2.0 µmol.g - 1 , respectively. On the other hand, Ni-Fe(3.0)/TiO 2 consisted of NH 3 desorption peaks at 214 °C and 626 °C with acid site amounts of 3.3 µmol.g - 1 and 2.0 µmol.g - 1 , respectively. Both Ni-Co(3.0)/TiO 2 and Ni-Fe(3.0)/TiO 2 catalysts were found to be active for the selective hydrogenation of FFald to furfuryl alcohol (FFalc) at low temperature of 110 °C, H 2 3.0 MPa, 3 h with FFalc selectivity of 81.1% and 82.9%, respectively. High yields of CPO (27.2%) and CPL (41.0%) were achieved upon Ni-Fe(3.0)/TiO 2 when the reaction temperature was increased to 170 °C, 3.0 MPa of H 2 , and a reaction time of 6 h. The yield of CPO+CPL on the reused catalyst decreased slightly after the second reaction run, but the activity was maintained for at least three consecutive runs.

In order for Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group to publish and disseminate research articles, we need non-exclusive publishing rights (transfered from author(s) to publisher). This is determined by a publishing agreement between the Author(s) and Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group. This agreement deals with the transfer or license of the right for publishing to Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group, while Authors still retain significant all copy rights to use and share their own published articles. Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group supports the need for authors to share, disseminate and maximize the impact of their research and these rights, in any databases.
As a journal Author, you have all copy rights for a large range of uses of your article, including use by your employing institute or company.
