本文用热水法制备了不同Pr掺杂量的花状Ce x Pr 1-x O 2-δ 固溶体材料,并研究了其结构特性以及对CO氧化的催化活性。实验发现随着Pr掺杂量的增加,Ce x Pr 1-x O 2-δ 固溶体中的氧空位含量不断增加,当Pr掺杂量为30mol.%时,氧空位含量最高。10mol.%Pr掺杂的样品在CO氧化催化反应中活性最好,这可能跟Ce元素的还原性能和氧空位含量有关。

第二次工业革命以来,人类的生存和发展主要依赖于化石能源(煤炭、石油和天然气),世界能源消费结构中化石能源比例大于80％,中国的化石能源比例更大(大于90％).化石能源是一类不可再生资源,需要经过数百万年乃至上亿年才能形成,且传统的化石能源利用方式会产生碳氧化物、硫氧化物等环境污染物.世界各国为了争夺石油资源,不断引发战争;石油开采和精炼过程中产生的有毒有害气、液体,严重污染了环境;各国海洋石油勘探开发溢油污染事故频发,对海洋环境保护和近邻居民的生活带来了巨大的危害.为了降低对化石能源的依赖和降低温室气体排放,世界各国都在大力发展可再生能源,如风能、太阳能、生物质能、氢能、燃料电池等.

Nanostructured ceria materials have attracted wide attention as catalysts, and the doping of these materials with rare earth elements to modify their catalytic activity has been comprehensively investigated. A novel type of Ni-doped hierarchical nanostructured peony-like ceria (PCO) has been prepared and its catalytic activity is investigated and compared with that of Ni-loaded samples. The prepared Ni-doped ceria have nanoscale grain sizes and open mesopores. This unique morphology endows it with superior catalytic activity for the oxidation of CO and the partial oxidation of methane. It is found that extra oxygen vacancies are generated in the ceria, and the reducibility of the ceria is highly enhanced after Ni-doping. The catalytic activity for CO oxidation is improved after Ni-doping, compared with that of pure ceria and Ni-loaded ceria. In the reaction for the partial oxidation of methane, the 3.8 atm% Ni-loaded PCO sample realizes a higher CH4 conversion than the Ni-doped ceria. However, it is found that the onset temperature for CH4 conversion decreases from 400 degrees C for the pure PCO and 3.8 atm% Ni-loaded PCO sample, to 340 degrees C for the 5.7 atm% Ni-doped PCO sample.

Solid oxide fuel cells (SOFCs) are electrochemical reactors that can directly convert the chemical energy of a fuel gas into electrical energy with high efficiency and in an environment-friendly way. The recent trends in the research of solid oxide fuel cells concern the use of available hydrocarbon fuels, such as nature gas. The most commonly used anode material Ni/YSZ cermet exhibits some disadvantages when hydrocarbons were used as fuels. Thus it is necessary to develop alternative anode materials which show a mixed conductivity under fuel conditions. This article reviews the recent developments of anode materials for SOFCs with carbon-based fuels. The future trend in this field is briefly summarized as well.

Cerium oxide is a promising material for electrodes and electrolytes of solid oxide fuel cells (SOFCs). Lowering the sintering temperature of the electrolyte will bring a lot of benefits to the fabrication of SOFCs. This paper evaluates the feasibility of using lithium oxide as a sintering aid to reduce the densification temperature of samarium-doped ceria (Ce0.8Sm0.2O1.9, SDC) by SEM and electrochemical impedance spectroscopy. It is shown that the addition of Li2CO3 can indeed decrease the sintering temperature of SDC. More attention is paid to understand the aiding mechanism of Li2CO3. Raman spectroscopy and thermal analysis indicate that it is Li2O, a decomposition product of Li2CO3, that facilitates the sintering by way of a liquid phase sintering effect on the grain boundaries of SDC. These findings help to promote the application of ceria-based electrolytes for intermediate temperature SOFCs.

Herein, we introduce a novel material of flowerlike mesoporous CeO2 microspheres with nanointerspace, which was a kind of multifunctional material for both clean and renewable energy technologies. Catalyst of nickle oxide based on flowerlike cerium microspheres with high dispersion was made to achieve simultaneous dehydrogenation of ethanol and water molecules on multiactive sites. This special morphology catalyst represented novel stability more than 2000 h for hydrogen production at low temperature ethanol steam reforming. And, the molecules of poisonous volatile organic compounds (VOCs) such as benzene, HCN and so on could be adsorped chemically by this CeO2 microspheres based materials easily at room temperature. And, carbon monoxide could be converted to carbon dioxide lower than 100 degrees C by this CeO2 microspheres based materials, without rare metals.

Cu, Mn and Ag nanoparticles are loaded on nanostructured mesoporous CeO2 as catalysts for CO oxidation. The Cu/CeO2 catalyst exhibits an obvious deactivation after the stability test at 95 degrees C for 60 h. This is caused by carbon deposition as confirmed by FTIR spectroscopy, Raman spectroscopy and thermogravimetry-differential scanning calorimetry-mass spectroscopy (TG-DSC-MS) analysis. It is found that the Cu-Mn or Cu-Ag binary metal catalysts supported on the nanostructured CeO2 exhibit much improved activity and stability in CO oxidation. In ease case, carbon deposition is absent in the similar stability test, due to enhanced oxygen adsorption property.

Previously, hydrothermally prepared mesoporous peony-like ceria (PCO) material was shown to exhibit superior catalytic properties for CO oxidation and ethanol reforming. Ni supported PCO had been shown to have high activity for ethanol steam reforming at low temperature. In this work, Ag, Cu and Mn is co-loaded with Ni on PCO catalysts by impregnation method. The catalysts were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), and a combined thermogravimetry, differential scanning calorimetry, and mass spectrometry (TG-DSC-MS). It was found that all the catalysts gave 100% ethanol conversion above ca. 300°C and exhibited similar H2 yield. It is found that the severe coking problem for the Ni-loaded PCO catalyst was alleviated significantly if Ag, Cu or Mn is co-loaded. Among them, the addition of Mn is the most effective in reducing carbon formation.

Mesoporous peony-like ceria has been previously investigated to exhibit superior catalytic properties for CO oxidation, ethanol reforming and anode catalysts for low temperature SOFC. In this work, morphological and catalytic stability are investigated upon heat treatments in reducing and oxidizing atmosphere at temperatures between 300 and 600°C. Although the peony-like appearance remains stable upon heat treatment at 600°C for up to 72h, the BET surface area decreases from 150 to 30m2g−1 with nanocrystalline size increased from 6 to 15nm. Catalytic activity of CO oxidation decreases such that T50 (temperature for 50% conversion) increases from 153 to 197°C. Although morphological variation is more prominent significant upon treatment in reducing atmosphere, the catalytic activity for CO oxidation degrades less than in oxidizing atmosphere. Oxygen vacancies produced upon reduction treatment are responsible for the superior catalytic activity despite the morphological disadvantage.

Catalysts of nano-sized nickel oxide particles based on flowerlike lanthanum oxide microspheres with high disperse were prepared to achieve simultaneous dehydrogenation of ethanol and water molecules on multi-active sites. XRD, SEM, 77K N-2 adsorption were used to analyze and observe the catalysts' structure, morphology and porosity. Catalytic parameters with respect to yield of H-2, activity, selectivity towards gaseous products and stability with time-on-stream and time-on-off-stream were all determined. This special morphology NiO/La2O3 catalyst represented more than 1000 h time-on-stream stability test and 500 h time-on-off-stream stability test for hydrogen fuel production from ethanol steam reforming at 300 degrees C without any deactivation. During the 1000 h time-on-stream stability test, ethanol water mixtures could be converted into H-2, CO, and CH4 with average selectivity values of 57.0, 20.1, 19.6 and little CO2 of 3.2 mol%, respectively, and average ethanol conversion values of 96.7 mol%, with H-2 yield of 1.61 mol H-2/mol C2H5OH. During the 500 h time-on-off-stream stability test, ethanol water mixtures could be converted into H-2, CO, CH4 and CO2 with average selectivity values of 65.1, 17.3, 15.1 and 2.5 mol%, respectively, and average ethanol conversion values of 80.0 mol%. For the ethanol-H-2 and petrolic hybrid vehicle (EH HV), the combustion value is the most important factor. So, it was very suitable for the EH HV application that the low temperature ethanol steam reforming products' distribution was with high H-2, CO, CH4 and very low CO2 selectivity over the special NiO/La2O3 flowerlike microspheres.
