The invention provides a method for preparing 5-hydroxymethylfurfural by catalyzing through loaded type ferric phosphate. The method comprises the following steps: taking a mixed solution of water and acetone as a reaction medium, taking a biomass as a raw material and taking loaded type ferric phosphate SiO2-FePO4 as a catalyst; preparing the 5-hydroxymethylfurfural by utilizing a one-pot method. The method has the advantages that the raw material is green and environment-friendly and is cheap and easy to obtain; reaction conditions are moderate and the catalyst is a multi-phase catalyst, is easy to recycle, has no toxin and no corrosion to equipment and has the advantages of low price and easy availability; a whole reaction process is simple and convenient to operate and is green and environment-friendly. 种负载型磷酸铁催化制备5-羟甲基糠醛的方法，以水和丙酮的混合溶液为反应介质，生物质为原料，负载型磷酸铁SiO-FePO作为催化剂，利用锅法制备5-羟甲基糠醛。该方法原料绿色环保、廉价易得，反应条件温和，催化剂为多相催化剂，易回收利用，无毒，对设备无腐蚀，且具有廉价易得的多重优点，整个反应过程操作简便，绿色环保。
