Preparation method of titanate nano material uniformly loaded with elemental gold

The invention provides a preparation method of a titanate nano material uniformly loaded with elemental gold. The method comprises the following steps of: adding tetrachloroauric acid into an ethylenediamine solution to prepare a gold-ethylenediamine precursor; adding amorphous titanium dioxide into an alkaline solution, and carrying out hydrothermal reaction at 120DEG C for 12 hours to obtain a titanate carrier; and mixing the gold-ethylenediamine precursor with the titanate carrier, fully stirring the substances uniformly, and performing centrifuging, washing and drying to obtain the titanate nano material uniformly loaded with elemental gold. The preparation method provided by the invention is simple in process and convenient to operate, does not need to additionally introduce a reducing agent, and can realize reduction preparation of elemental gold through a self-contained organic ligand; the material prepared by the method has a spherical flower-like morphology, and has the advantages of uniform gold par
