Abstract: This article used the water hot process to prepare the CeO2 carrier, again deposited the precipitation method and the co-precipitation law has separately prepared the corresponding Au /CeO2 catalyst, responded take the CO oxidizing reaction as the probe, inspected the catalyst different preparation method to the catalyst performance influence, and diffracted (XRD) and the transmission electron microscope through X beam powder (the TEM attribute method has carried on the attribute to the carrier and the catalyst structure, has analyzed the influence catalyst active reason. The experimental result indicated that, the water used hot process preparation CeO2 carrier particle size small (about 18nm) also the distribution is even, can see clearly from the electron microscope chart to CeO2(111) crystal face crystal lattice spacing. In the Au /CeO2 catalyst deposits the Au /CeO2 catalyst gold crystal grain which precipitation method load Au obtains to disperse highly in the carrier surface also the active constituent and the carrier contact is close, compared with the carrier displays the very high catalytic activity. Key word: Au /CeO2 catalyst, water hot process, CeO2 carrier, CO catalytic activity
