The invention discloses a bimetallic composite biochar catalyst for sugar acid synthesis, and a preparation method of the catalyst comprises the following steps: crushing and sieving biomass to obtain biomass powder; adding the biomass powder, platinum salt and/or zinc salt and alkali salt into an organic solvent, and carrying out solvothermal reaction; and washing the obtained material with absolute ethyl alcohol and ultrapure water, and drying to obtain the bimetallic composite biochar catalyst for sugar acid synthesis. According to the invention, the straw is used as a raw material, so that recycling of the straw is realized; the straw-based porous biochar material loaded with Pt and Zn bimetals is synthesized in one step through a solvothermal method, and the synthesis route is greener and safer; the polyhydric alcohol solution reduces part of platinum at high temperature, and transition metal zinc is introduced, so that not only can a biomass derivative C5/C6 unit be efficiently converted into saccharic
