| description | The invention relates to application of a catalyst carrier, in particular to application of a nanometer composite aerogel catalyst carrier in the field of diphenyl carbonate synthesis. The application comprises preparation of the nanometer composite aerogel catalyst carrier, preparation of a load type catalyst and catalytic synthesis of diphenyl carbonate, by the following steps: dissolving a main catalyst PdCl2 and an auxiliary catalyst Co(OAc)2 in weak aqua ammonia; and weighing CuO(CoO, MnO)/SiO2 nanometer composite aerogel catalyst carrier, immersing the CuO(CoO, MnO)/SiO2 nanometer composite aerogel catalyst carrier in the aqua ammonia solution with the main catalyst and the auxiliary catalyst, and drying the mixture in vacuum; carrying out heat treatment on the dried catalyst at a temperature of 600 DEG C in oxidizing atmosphere to prepare the load type catalyst; and catalytically synthesizing the load type catalyst to prepare the diphenyl carbonate by an oxidative carbonylation method.
