A series of nickel phosphide catalysts with adjustable Brønsted 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 Brønsted acid sites.

以双（三苯基膦）二氯化镍为“多合一”前体，通过液相法制备了一系列具有可调布朗斯台德酸位和路易斯酸位的磷化镍催化剂。通过XRD，TEM，³¹ P魔角旋转（MAS）NMR，XPS和NH ₃ -TPD表征催化剂。然后，在糠醛的液相加氢脱氧成2-甲基呋喃中测试了其催化性能。全糠醛转化率和91.2％的2-甲基呋喃和良好的催化稳定性的选择性可以通过将Ni来实现₂的最佳反应条件下P-1.00-300催化剂（1.5兆帕ħ ₂，260℃，3小时），这归因于路易斯酸位与布朗斯台德酸位之间的协同作用。
