“…In recent years, a major leap forward has been achieved through the application of advanced analytical techniques, such as the nuclear magnetic resonance (NMR) [27] and Fouriertransform ion cyclotron resonance mass spectrometry (FT-ICR MS) [28]. Specifically, this system is the only means for resolving the composition of complex feedstock at a molecular level, as demonstrated with bio-blends [29,30], crude-derived heavy feedstock [28,31], and even hydrocarbon species responsible for catalyst deactivation [32,33].…”

Transition metal phosphide nanoparticles supported on silica were used as catalysts to investigate the hydrodeoxygenation of methyl laurate (used as a model compound for vegetable oils). Ni2P, Ni1Mo1P, and Ni1.6Mo0.4P were synthesized using a molecular precursor route. The nanoparticles were added to the silica support without any changes in their structure or particle size. As a reference and for comparison, MoP/SiO2 was also prepared by the phosphite method. The prepared catalysts were characterized by X‐ray diffraction, X‐ray photoelectron spectroscopy, transmission electron microscopy, and chemical analysis. A higher conversion is reached with the MoP/SiO2 monometallic catalyst, close to that with Ni1Mo1P/SiO2. However, this observation is misleading because the differences in dispersion obscure the result that the intrinsic activity (turnover frequency) of the bimetallic catalyst, prepared by a molecular precursor route, is significantly higher than that of the monometallic catalyst, prepared by the phosphite route, revealing a synergistic effect on the catalytic activity due to the formation of the bimetallic phosphide.
