1. A preparation method of an oxygen-vacancy-rich MoOx/ZrO2 catalyst in hydrodeoxygenation of a biomass gas-solid system, comprising the following steps:
(1) preparation of oxygen-vacancy-rich ZrO2: dissolving zirconyl nitrate and ammonia water in de-ionized water respectively and then mixing fully and performing aging, cooling, filtering, washing, and drying to obtain a solid powder and calcining the solid powder in an air atmosphere to obtain a ZrO2 solid;
(2) adding ammonium molybdate tetrahydrate into de-ionized water for dissolution, stirring and dropwise adding into the ZrO2 solid obtained in the step (1), and mixing to make loading uniform, and then drying to obtain a first solid, and then grinding the first solid and calcining in the air atmosphere to obtain an MoOx/ZrO2 powder; and
(3) adding a Pt precursor into de-ionized water for dissolution, and dropwise adding into the MoOx/ZrO2 powder obtained in the step (2) and stirring to make loading uniform, and then drying to obtain a second solid, and then grinding the second solid and calcining in the air atmosphere to obtain a Pt—MoOx/ZrO2 catalyst.
