Several recent studies have shown that the hydrotreating properties of monometallic phosphides can be improved by incorporating a second metal due to the synergistic effect. A catalyst having a composition of Fe0.03Ni1.97P2.00/SiO2has shown 40% increase in hydrodesulfurization catalytic activity than the optimized nickel phosphide catalyst.However, no systematic study has been done on particle size effects on HDS activity of Fe2-xNixP, largely because traditional incipient wetness techniques do not enable sufficient size control. In this presentation, the compositional and size dependent catalytic activities are presented for Fe2-xNixP nanoparticles. The sintering of Fe2-xNixP nanoparticles on traditional supports is overcome by incorporation of nanoparticles within mesoporous silica.
