1Ethanol steam reforming over Ni-Cu/Al_2O_3-M_yO_z (M = Si, La, Mg,and Zn) catalysts显示文摘Ni-based catalysts doped with copper additives were studied on their role in ethanol steam reforming reaction. The effects of Cu content, support species involving Al2O3-SiO2, Al2O3-MgO, Al2O3-ZnO, and Al2O3-La2O3, on the catalytic performance were studied. Characterizations by TPR, XRD, NH3-TPD, XPS, and TGA indicated that catalysts 30Ni5Cu/Al2O3-MgO and 30Ni5Cu/Al2O3-ZnO have much higher H2 selectivity than 30Ni5Cu/Al2O3-SiO2, as well as good coke resistance. H2 selectivity for 30Ni5Cu/Al2O3-MgO catalyst was 73.3% at 450 °C and increased to 94.0% at 600 °C, whereas for 30Ni5Cu/Al2O3-ZnO catalyst, the H2 selectivity was 63.6% at 450 °C and 95.2% at 600 °C. These Al2O3-MgO and Al2O3-ZnO supported Ni-Cu bimetallic catalysts may have important applications in the production of hydrogen by ethanol steam reforming reactions.Lifeng Zhang Jie Liu Wei Li Cuili Guo Jinli Zhang 2009Journal of Natural Gas Chemistry2009,18,1:5

3Effect of doped Ni-Bi-B alloy on hydrogen generation performance of Al-InCl3显示文摘In this work,Ni-Bi-B alloy has been synthesized via chemical synthesis method.A new kind of Al-InCl3-(Ni-Bi-B)composite has been prepared by high energy mechanical ball grinding A1 powder with additives.Results show that the doped Ni-Bi-B alloy can significantly improve the hydrogen generation performance of Al-InCl3 and the catalytic activity is enhanced with the increasing content of Bi in Ni-Bi-B alloy.Under optimal conditions,the hydrogen generation yield and conversion yield of Al-InCl3-(Ni-Bi-B)reached1196.8 mL g^-1 and 100.0%at room temperature,respectively.Mechanism study shows five kinds of active sites,such as the fresh surface/defect of Al particle,Al-AlCl3,Al-In,Al-Bi/B and Al-Ni/B produced during the ball milling process.Their synergistic effect enhances the hydrogen generation performance of AlInCl3-(Ni-Bi-B)remarkably.In general,the proposed Al-InCl3-(Ni-Bi-B)composite is possible to serve as hydrogen generation material for fuel cells.Jun Chen F.Xu L.Sun Kexiang Zhang Yongpeng Xia Xiaolei Guo Huanzhi Zhang Fang Yu Erhu Yan Hongliang Peng Pengru Huang Shujun Qiu Cuili Xiang Yujie Sun 2019Journal of Energy Chemistry2019,28,12:1

5Highly Dispersed Pd Nanoparticles Supported on Zr-Doped MgAl Mixed Metal Oxides for 2-Ethylanthraquinone Hydrogenation显示文摘In this study,Pd-Mg(Al)-LDH/γ-Al2O3 and Pd-Mg(Al)Zr-LDH/γ-Al2O3 precursors were synthesized by impregnating Na2PdCl4 on Mg(Al)-LDH/γ-Al2O3 and Mg(Al)Zr-LDH/γ-Al2O3,and then the precursors were calcinated and reduced to obtain Pd-Mg(Al)-MMO/γ-Al2O3 and Pd-Mg(Al)Zr-MMO/γ-Al2O3 catalysts.Compared with Pd/γ-Al2O3 catalyst,the hydrogenation efficiency of Pd-Mg(Al)-MMO/γ-Al2O3 and Pd-Mg(Al)Zr-MMO/γ-Al2O3 increased by 15.7%and 24.0%,respectively.Moreover,the stability of Pd-Mg(Al)Zr-MMO/γ-Al2O3 catalyst was also higher than that of Pd/γ-Al2O3.After four runs,the hydrogenation efficiency of Pd/γ-Al2O3 decreased from 12.1 to 10.0 g/L,while that of Pd-Mg(Al)Zr-MMO/γ-Al2O3 decreased from 15.0 to 14.3 g/L.The active aquinones selectivities of all catalysts were almost 99%.The structures of the catalysts were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),N2 adsorption–desorption,inductively coupled plasma-atomic emission spectrometry(ICP-AES),CO chemisorption analysis,transmission electron microscopy(TEM),temperature-programmed reduction with hydrogen(H2-TPR),and X-ray photoelectron spectroscopy(XPS).The results indicate that the improved catalytic performance is attributed to the stronger interaction between Pd and Mg(Al)Zr-MMO/γ-Al2O3,smaller Pd particle size and higher Pd dispersion.This work develops an effective method to synthesize highly dispersed Pd nanoparticles based on the layered double hydroxides(LDHs)precursor.Yunhao Wang Kaige Gao Chenliang Ye Ang Li Cuili Guo Jinli Zhang 2019Transactions of Tianjin University2019,25,6:1
6Differences of Physicochemical Properties Between Chalky and Translucent Parts of Rice Grains显示文摘Rice grain chalkiness is an important characteristic,but the difference between chalky and translucent parts in grains is still unclear.Here,we investigated the differences of flour made from the chalky or translucent part of rice grains in three indica and three japonica rice varieties.The chalky flour had significantly lower amylose and protein contents and looser starch granule morphology,and starches in the chalky flour had higher relative crystallinity,higher short chain content but lower long chain content than those in the translucent flour.The water states,determined with nuclear magnetic resonance,differed between the chalky and translucent flour after soaking,cooking and retrograding,and the chalky flour had more bound and free water but less constructural water than the translucent flour.Mostly,the chalky flour had lower viscosity and shorter gel consistency,but higher onset temperature and gelatinization enthalpy than the translucent flour.The results indicated that starch granule morphology would be more indicative than other attributions on pasting and gelatinization properties of chalky and translucent parts of rice grains.WANG Cuili GUO Wen HU Peisong WEI Xiangjin TANG Shaoqing JIAO Guiai 2022Rice science2022,29,6:0
7AlCl_(3)modified Pd/Al_(2)O_(3)catalyst for enhanced anthraquinone hydrogenation显示文摘Anthraquinone hydrogenation to produce H_(2)O_(2) is an economically interesting reaction with great industrial importance.Here,we report a series of Pd/xAl catalysts with different AlCl_(3) contents by a conventional stepwise impregnation method.The optimal Pd/1.0Al catalyst exhibits a higher performance toward anthraquinone hydrogenation with 8.3 g·L^(-1)hydrogenation efficiency,99.5%selectivity and good stability,obviously superior to that of Pd/Al_(2)O_(3) catalyst(5.2 g·L^(-1)and 97.2%).Detailed characterization demonstrates that AlCl_(3) can be grafted on the γ-Al_(2)O_(3) support to obtain a modified support with abundant surface weak acid and Lewis acid,which can adsorb and activate anthraquinone.Meanwhile,its steric hindrance could isolate and disperse active metals to form more active sites.The synergies between metal sites and acid sites promotes the anthraquinone hydrogenation.Furthermore,the good stability after grafting AlCl_(3) could attribute to the enhanced metal-support interaction inhibiting metal particles agglomeration and leaching.Qinqin Yuan Jingyue Liang Wei Li Jinli Zhang Cuili Guo 2023Chinese Journal of Chemical Engineering2023,64,12:0
8Effect of the support calcination temperature on selective hydrodesulfurization of TiO_2 nanotubes supported CoMo catalysts显示文摘TiO2 nanotubes(TiO2-NTs) were synthesized by the hydrothermal method.Co and Mo active components were supported on a series of the as-prepared TiO2-NTs samples which were calcined at different temperatures.The effects of support calcination temperature of CoMo/TiO2- NTs catalysts on their catalytic performance were investigated for selective hydrodesulfurization(HDS).The samples were characterized by means of the scanning electron microscopy(SEM),the transmission electron microscopy(TEM),N2 adsorption-desorption,X-ray diffraction (XRD),Raman spectroscopy and H2 temperature-programmed reduction(H2-TPR).The experimental results revealed that TiO2-NTs support calcined under 500℃can maintain the nanotubular structure with higher surface area and pore volume.Meanwhile,the obtained supported CoMo/TiO2-NTs catalysts exhibited weak metal-support interaction,more octahedral Mo6+ species and high catalytic performance in selective HDS.Cuili Guo Yuanyuan Wu Xin Wang Bo Yang 2013Journal of Energy Chemistry2013,22,3:0
