▎ 摘　　要

NOVELTY - Nickel phosphide/reduced graphene oxide catalyst is claimed. The catalyst is prepared by taking reduced graphene oxide as carrier, and nickel phosphide as loaded active component, where loading amount of nickel phosphide is 10-25%. USE - The catalyst is useful in bio-oil hydrodeoxygenation reaction (claimed). ADVANTAGE - The catalyst: has mild reaction conditions, conversion rate of more than 96%, high selectivity, strong stability and low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing nickel phosphide/reduced graphene oxide catalyst comprising loading 10-25% nickel phosphide, mixing nickel element and phosphorus element is 2:1.5, ultrasonically dispersing graphene oxide in mixed aqueous solution of sodium hypophosphite and nickel(II) chloride hexahydrate or nickel(II) nitrate hexahydrate, adding hydrazine hydrate, reacting at 70-90 degrees C for 3-5 hours, filtering, repeatedly washing filter cake with deionized water, vacuum drying at 50-80 degrees C, and baking at 300-400 degrees C for 3-5 hours under nitrogen gas atmosphere to obtain nickel phosphide/reduced graphene oxide catalyst.
