The invention discloses a supported Anderson type heteropolyacid catalyst for preparing tributyl citrate and a preparation method and application of the supported Anderson type heteropolyacid catalyst. The preparation method includes the steps of firstly, dissolving ammonium molybdate into water, and heating until boiling is achieved; adding a cobalt sulfate solution into the ammonium molybdate solution, stirring, and filtering while the mixed solution is hot; allowing filtrate to stand to wait for crystallization so as to obtain [CoIIMo6] Anderson type polyacid; secondly, preparing the polyacid into an aqueous solution, adding SBA-15 mesoporous molecular sieves into the aqueous solution, performing hydrothermal reaction, centrifuging, and drying to obtain the catalyst. The preparation method has the advantages that the preparation method is simple in process and needed equipment, mild in reaction condition and environmentally friendly; the prepared supported Anderson type heteropolyacid catalyst used for pre
