Co-Pd bimetallic catalysts immobilized with four kinds of resins with different specific areas were prepared by means of the solvated metal atom impregnation (SMAI) method. The results of the XRD and the magnetic measurement showed that as the specific area of the resin increased, the particle sizes of Co and Pd on the catalysts with the same metal content decreased, so the catalytic activity of the catalysts for the hydrogenation of diacetone alcohol as well as the reduction of oxygen on the fuel cell electrode increased. Below 140℃, the conversion of diacetone alcohol increased as the reaction temperature increased, and above 140℃ the conversion decreased because of the rupture of the resin.

Copper oxide catalysts supported on ceria were prepared by wet impregnation method using finely CeO2 nanocrystals, which was derived from alcohothermal synthesis, and copper nitrate dissolved in the distilled water. The catalytic activity of the prepared CeO2 and CuO/CeO2 catalysts for low-temperature CO oxidation was investigated by means of a microreactor-GC system. The samples were characterized using BET, XRD, SEM, HRTEM and TPR.

Cu/CeO2 and CuO/CeO2 catalysts were prepared by solvated metal atomimpregnation (SMAI) andconventional impregnation (CI) and used for carbonmonoxide oxidationin CO and air. The catalysts were characterized by means of XRD, XPS, AES and H2-TPR techniques. The Cu/CeO2 catalyst prepared via SMAI exhibits higher catalytic activity in CO oxidation than that prepared via CI with the saiile Cucontent due to the smaller Cu particles The CuO/CeO2 catalyst prepared via SMAI also shows higher catalytic activity than that prepared via CI because the CuO particles of the former are smaller than the latter and can be reduced by CO more easily. The Cu/CeO2 catalysts elisplay higher catalytic activities than CuO/CeO2 catalysts with the same Cu content and prepared by the same method. The TPR profile for CuO/CeO2 catalyst prepared via SMAI has a single peak, indicating a one-step reduction, whereas the TPR profile for CuO/CeO2 catalyst prepared via CI has two peaks indicating a two-step reduction due to the existence of two kinds of CuO species.

Supported Au catalysts for low-temperature CO oxidation were prepared by solvated metal atom impregnation (SMAI) and conventional impregnation (CI). X-ray photoelectron spectroscopy investigations indicated that gold in all the samples was in the metallic state. TEM and XRD measurements showed that the mean diameter of Au particles prepared by SMAI was smaller than that of those prepared by CI with the same gold content. Catalytic tests showed that SMAI catalysts had higher CO oxidation activity than CI catalysts with the same compositions. Both SMAI and CI Au/TiO2 catalysts exhibited high activities in low temperature CO oxidation. Full CO conversion was obtained at 323K for 3.1 wt.% Au/TiO2 (SMAI) catalyst, which displayed higher activity than the 3.1 wt.% Au/D-72 (SMAI) and 3.1 wt.% Au/TiO2 (CI). Although the sizes of gold particles prepared by the same method and supported on both TiO2 and resin were comparable, the Au/TiO2 catalysts showed significantly higher activities than the Au/resin catalysts with the same Au contents under the same reaction conditions. These results prove that not only the gold particle size, but also the support plays a key role in CO oxidation.

用沉积-沉淀法制备了不同金含量的Au/SnO2催化剂。采用XRD和UV-Vis等手段对催化剂样品进行了表征并考察了沉积溶液的pH值、金的负载量、焙烧温度和气氛等对Au/SnO2催化CO氧化活性的影响。结果表明:当沉积溶液的pH=9~10时,所制得的金属金的平均粒径最小;随着金的负载量的增大,金属金的粒径增大,Au/SnO2的催化活性降低;在所研究的条件下,Au/SnO2前驱体在空气中473K下焙烧4h,得到的催化剂活性最高;在氢气中373K下处理2h的Au/SnO2的催化活性在所有样品中是最高的。
