The diverse catalytic activity obtained from Ni2P-noble metal catalysts in the hydrodeoxygenation reaction. The influence of using noble metal promoters such as platinum, iridium, palladium, and ruthenium on Ni2P catalysts in hydrodeoxygenation reactions with various compounds is still not fully understood, thus further research is needed to comprehend these effects. The purpose of this study is to synthesize Ni2P-noble metal/AC catalysts using the incipient wetness impregnation method, with Ni2P-noble metal/AC catalysts containing a nickel metal loading of 8% wt and noble metals of 2% wt. The Ni2P-noble metal/AC catalysts were obtained through a drying process at 100°C for 12 hours and a reduction process at 600°C for 3 hours. The Ni2P-noble metal/AC catalysts were characterized using XRD, BET-BJH Analyzer, NH3-TPD, H2-TPR, FE-SEM-EDS, and TEM. XRD analysis results showed peaks indicating the presence of activated carbon (AC), Ni2P, and Ni12P5. The characterization results of the Ni2P-Pt/AC, Ni2P-Ir/AC, Ni2P-Pd/AC, and Ni2P-Ru/AC catalysts using XRD analysis revealed peaks indicating the presence of activated carbon (AC), Ni2P, and Ni12P5. BET-BJH Analyzer analysis showed that the BET surface area of the Ni2P-Pd/AC catalyst is relatively low compared to other Ni2P-noble metal/AC catalysts. The NH3-TPD analysis results show that the Ni2P-Ru/AC and Ni2P-Pd/AC catalysts have high acidity because the Ru and Pd promoters have higher acidity values compared to Pt and Ir. H2-TPR analysis results showed that the Ni2P-Pd/AC catalyst had the highest H2 uptake among the Ni2P-noble metal/AC catalysts. FE-SEM-EDS analysis results demonstrated a uniform distribution of active substances for Ni2P-Pd/AC and Ni2P-Ru/AC and a tendency for active substances to cluster for Ni2P-Pt/AC and Ni2P-Ir/AC catalysts. TEM analysis showed a uniform distribution of active substances within the internal structure of the Ni2P-Pt/AC catalyst. Based on the research results, the highest liquid fraction was obtained using the Ni2P-Ru/AC catalyst under reaction conditions of 350°C, catalyst weight of 0.5 g, stirring speed of 500 rpm, H2 pressure of 40 bar, and reaction time of 3 hours, with a yield of 75.04%. The Ni2P-Pt/AC catalyst showed the best catalytic properties among the four other catalysts for the hydrodeoxygenation reaction of stearic acid.
