A series of nickel phosphide catalysts with adjustable Bronsted acid sites and Lewis acid sites has been prepared by liquid-phase method using bis(triphenylphosphine) nickel dichloride as “all-in-one” precursors. The catalysts were characterized by XRD, TEM, 31P magic angle spinning (MAS) NMR, XPS, and NH3-TPD; then, its catalytic performance was tested in the liquid-phase hydrodeoxygenation of furfural to 2-methylfuran. The full furfural conversion and the selectivity for 2-methylfuran of 91.2% and the good catalytic stability can be achieved over the Ni2P-1.00-300 catalyst under the optimal reaction conditions (1.5-MPa H2, 260 °C, 3 h), which is attributed to the synergy between Lewis acid sites and Bronsted acid sites.
