【期刊论文】Synthesis and electrochemical properties of mesoporous 4 nickel oxide

Mesoporous Ni(OH)2 is synthesized using sodium dodecyl sulfate as a template and urea as a hydrolysis-controlling agent. Mesoporous NiO with a centralized pore-size distribution is obtained by calcining Ni(OH)2 at different temperatures. The BET specific surface area reaches 477.7m2 g?1 for NiO calcined at 250℃. Structure characterizations indicate a good mesoporous structure for the nickel oxide samples. Cyclic voltammetry shows the NiO to have good capacitive behaviour due to its unique mesoporous structure when using a large amount of NiO to fabricate the electrode. Compared with NiO prepared by dip-coating and cathodic precipitation methods, mesoporous NiO with a controlled pore structure can be used in much larger amounts to fabricate electrodes and still maintain a high specific capacitance and good capacitive behaviour.

【期刊论文】Synthesis and Stabilization of Nanocrystalline Zirconia with MSU Mesostructure

In the presence of nonionic block-copolymer surfactant, nanocrystalline zirconia particles with MSU mesostructure were synthesized by a novel solid-state reaction route. The zirconia particles possess a nanocrystalline pore wall, which renders higher thermal stability compared to an amorphous framework. To further enhance its stability, laponite, a synthetic clay, was introduced. Laponite acts as an inhibitor to crystal growth and also as a hard template for the mesostructure. High surface area and ordered pore structure were observed in the stabilized zirconia. The results show that the formation of the MSU structure is attributed to reverse hexagonal micelles, which are the products of the cooperative self-assembly of organic and inorganic species in the solid-state synthesis system with crystalline water and hygroscopic water present.

In this work, nanoporous nickel oxide was synthesized using anionic surfactant assembly method. Structure characterizations show that this nickel oxide possesses partlyordered mesoporous structure with nanocrystalline pore wall. The formation mechanism of wormlike nanoporous structure is ascribed to the quasi-reverse micelle system formed by ternary phases of SDS (sodium dodecyl sulfate)/urea/water. Cyclic voltammetry shows that these nickel oxide samples possess both good capacitive behavior due to its unique nanoporous structure and very high specic capacitance due to its high surface area with electrochemical activity.

【期刊论文】Mechanistic Study of Carbon Dioxide Reforming with Methane over Supported Nickel Catalysts
阎子峰, Zi-Feng Yan, * Rong-Gang Ding, Lin-Hua Song, and Ling Qian

-1年11月30日
Carbon dioxide reforming with methane to synthesis gas has been investigated in terms of the effects of active metal loading, feed ratio, and reaction temperature on catalyst activity and stability employing supported Ni, Co, and Fe catalysts. Temperature-programmed desorption, temperature-programmed surface reaction, and X-ray photoelectron spectroscopy experiments were conducted to elucidate the reaction mechanism. An interesting observation made was that the direct dissociation of methane without the involvement of adsorbed or gas-phase CO2 most likely occurs and that the formation of hydrogen and surface carbon species, which are both primary products of the decomposition of methane, is the key step for the reforming reaction. Carbon monoxide might be the secondary product formed by interaction between surface carbon species and gas-phase or adsorbed CO2. Three surface carbon species Cα, Cβ and Cγ, which are produced by the decomposition of methane, showed various mobility, thermal stability, and reactivity. In the meantime, the residual partial oxidative NiOx species that were not thoroughly reduced could not migrate on the catalyst surface and be stepwise reduced during the reaction.

在无任何稳定剂存在的条件下,用固态反应-结构导向合成出了介孔纳米二氧化锆分子筛。所得产品拥有层状虫孔结构,比表面明显高于文献值,同时,其介孔纳米特性稳定性高,在较高温度下仍能维持。将该样品引入到甲醇合成用Cu基催化剂后赋予催化剂纳米尺度,从而改变了催化剂的理化结构和电荷性质,使Cu基催化剂显示较高的催化活性和优良的选择性。由不同制备方法所得催化剂反应性能的差异,探讨了甲醇合成催化剂的可能活性位结构。

【期刊论文】Promotion Effects of Nickel Catalysts of Dry Reforming with Methane
阎子峰, YAN, Zi-Feng*, DING, Rong-Gang, LIU, Xin-Mei, SONG, Lin-Hua

The promotion effects of nickel catalyst of dry reforming with methane were extensively investigated by means of XRD, SEM, EDX, N2-adsorption and H2-adsorption. XRD characterization indicated that good dispersion of nickel oxide and MgO promoter is achieved over γ-Al2O3 support. Addition of MgO promoter effectively retards the formation of NiAl2O4 phase. SEM and EDX analysis exhibited that the addition of rare-earth metal oxide CeO2 effectively promotes the Ni metal dispersion on the surface of the catalysts despite of undesirable self-dispersion of CeO2 promoter. Furthermore, the nickel component is gradually dispersed on the surface of the support following the exposure to reaction gas mixture for a period of time. The addition of MgO inhibited the self-dispersion and promotion effect of CeO2 on Ni dispersion on the catalysts. H2 chemisorption revealed that the addition of the alkaline oxide MgO promoter significantly proinibits the metal dispersion on the catalyst. Inappropriate promoter addition can result in sharp decrease of the metal dispersion. N2-adsorptlon indicated that oxide promoter was mostly concentrated on the outer layer of the alumina support while the nickel metal was generally dispersed in the support pores. Addition of promoters contributed to more reduction in mesopore volume.

【期刊论文】Structure characterization of the Co and Ni catalysts for carbon dioxide reforming of methane
阎子峰, Rong Gang Ding, Zi Feng Yan*
Catalysis Today 2426(2001)1-9,-0001,():

The effects of active components, promoters and reforming reaction on structure variation of catalysts for carbon dioxide reforming with methane are extensively investigated. It is found that the active component and promoters disperse in different sites on the support. The impregnated metal species may be mainly located on the inner surface of the micropore of the support. The 8.5%Ni-2%MgO-3%CeO2/Al2O3 catalyst achieves best metal dispersion among the tested catalysts. It is also interesting to note that the addition of the alkaline oxide promoter (MgO) prohibits the metal dispersion on the support, while the addition of rare-earth metal oxide CeO2 effectively promotes the Ni metal dispersion on the surface of the support despite of unsatisfactory self-dispersion of CeO2 promoter.

在非缓冲体系下用柠檬酸对USY分子筛进行分子结构修饰,详细考察了各反应因素对分子筛改性效果的影响;并且用XRD,DTA,DTG,FT-IR,N2静态容量吸附法等物理手段对改性分子筛样品的结构及性能进行了表征,用MAT法评价了其催化裂化反应性能和对低碳烯烃的选择性能。发现改性后分子筛硅铝比、结晶度和热稳定性显著提高,晶胞常数相应减小;具有更加发达的孔结构,尤其二次孔含量明显增多;对低碳烯烃有较高的选择性和收率,酸性质取得了与文献一致的结论。
