用于巴豆醛液相选择性加氢的高性能Ir/TiH 2 催化剂

郑万彬 Zheng Wan-bin 叶艳文 YE Yan-wen 胡一鸣

在Ir/TiH2催化剂上进行了巴豆醛液相选择性加氢反应，并研究催化剂还原温度对其反应行为的影响.相比于Ir/TiO2催化剂，相同反应条件下Ir/TiH2催化剂的活性提高了2倍(80℃时巴豆醛转化率为52%)，且巴豆醇选择性大幅度提高(78%).表征结果表明，Ir/TiH2催化剂表面富含的氧缺位和强的H活化能力是催化剂性能提高的主要原因.此外，Ir/TiH2催化剂中Ir颗粒尺寸随催化剂还原温度的升高而增大，导致其本征活性降低，表现出明显的尺寸效应.较小的颗粒尺寸有利于巴豆醛分子中C=O键加氢，从而提高了催化剂的反应性能.

Characterization and Performance of CrOx-Y2O3 Catalysts for the Synthesis of 1,1,1,2-Tetrafluoroethane

Acta Physico-Chimica Sinica (2009)

Qian Lin XING Li-Qiong BI Qing-Yuan Hongfang Li Kefeng Chen

制备了一系列CrOx-Y2O3催化剂用于气相氟化1，1，1-三氟-2-氯乙烷（HCFC-133a）合成1，1，1，2－四氟乙烷（HFC－134a），并考察了Y（OH）3、YCl3和Y（NO3）3前躯体对催化剂性能的影响．XRD和UV—Vis光谱实验结果表明，Y前躯体对催化剂表面Cr物种有影响，其中采用Y（OH），前躯体的催化剂有利于以高分散的Cr^6＋形式存在．研究表明CrOx-Y2O3催化剂在预处理和反应过程中，部分高价CrO3可转化为CrF3-催化剂中CrF3含量增加，导致其转化为活性物种的含量相对减少，所以其催化活性下降．

The Direct Gas-Phase Epoxidation of Propylene on Sn-modified Au/TS-1 Catalysts

Journal of Molecular Catalysis(China) (2010)

Ji-Qing Lu

The direct propylene epoxidation in the presence of hydrogen and oxygen was studied over Au catalysts supported on a Sn-modified TS-1.The supported Au catalysts were prepared using the deposition-precipitation method.The effects of Sn contents on the structure and catalytic properties of catalysts were investigated.X-ray diffraction(XRD) and Fourier transform infrared(FTIR) spectroscopic results showed that the Sn was incorporated into the struture of the TS-1.The presence of Sn in the catalyst resulted in an increment of C3H6 concersion from 1.6% to 2.5% and PO selectivity from 87% to 90%,which may be due to a ligand effect.

Selective Hydrogenation of Crotonaldehyde over Ir–FeO_x/SiO₂ Catalysts: Enhancement of Reactivity and Stability by Ir–FeO_x Interaction

The Journal of Physical Chemistry C (2016)

Yu Qin Kyoko K. Bando Ju-Fang Yuan Ce-Qi Luo Aiping Jia

A series of FeOx-promoted Ir/SiO2 catalysts were prepared and tested for gas phase selective hydrogenation of crotonaldehyde. It was found that a catalyst containing Ir nanoparticles contacting with highly dispersed FeOx clusters (3Ir/0.1Fe/SiO2) showed excellent activity and stability, with a 5-fold enhanced steady state crotyl alcohol yield (59.6%) compared to that of the bare Ir/SiO2 (12.4%), while a catalyst promoted with high content of Fe (3Ir/3.5Fe/SiO2) had high initial activity but deactivated rapidly. A catalyst with similar highly dispersed FeOx clusters but prepared by an inverse impregnation sequence (0.1Fe/3Ir/SiO2) also suffered severe deactivation. Various characterizations revealed that the observed behaviors were closely related to the Ir–FeOx interactions induced by different morphologies of the catalysts. The active sites generated at Ir–FeOx interface were responsible for the better performance. The catalyst deactivation was attributed to the deposit of heavy compound and strong adsorption of CO on the surface, which was induced by the strong Ir–FeOx interaction due to heavy decoration of FeOx on the Ir surface.

Catalytic oxidation performance of supported CeO_2/OMS-2 catalysts for VOCs

Industrial Catalysis (2011)

Ji-Qing Lu

OMS-2 was synthesized using a reflux method,and CeO_2/OMS-2 catalysts were prepared by the impregnation method. The as-prepared catalysts were characterized by XRD, Raman, BET, H_2-TPR and NH_3-TPD techniques. The performance of CeO_2/OMS-2 catalysts for catalytic oxidation of dichlo-romethane and ethyl acetate were investigated. XRD results indicated that the octahedral molecular sieve structure of OMS-2 was not changed with the addition of CeO_2 and CeO_2 particles were highly dispersed on the surface of OMS-2. BET results showed that the surface area of the catalyst increased with the addition of CeO_2. H_2-TPR results indicated that with the increase of CeO_2 loadings,low temperature and high temperature reduction peaks first shifted to low temperature and then to high temperature. NH_3-TPD results indicated that with the increase of CeO_2 loadings, high temperature desorption peak assigned to strong acid first shifted to low temperature and then to high temperature. The results of reaction activity showed that the activity of Ce/OMS-2 catalysts were better than that of OMS-2 support. The highest reac- tivity was obtained over 1. 0Ce/OMS-2 catalyst (CeO_2 loading mass fraction 1.0% ) , probably due to the enhanced oxygen mobility and the weakened acidity of the catalyst by the addition of CeO_2.
