| 1 | Effect of loading on the Ni_2P/Al_2O_3 catalysts for the hydrotreating reactions显示文摘The 80%Ni2P/Al2O3 catalysts were prepared by the phosphidation of corresponding 80%Ni/Al2O3 with triphenylphosphine in liquid phase and compared with the 60%Ni2P/Al2O3 for hydrotreating reactions. Both the60%Ni2P/Al2O3 and 80%Ni2P/Al2O3 in comparison exhibited the small and uniform Ni2 P particles(6.3 and8.4 nm,respectively),high CO uptakes(305 and 345 μmol/g,respectively) and thus high activities for the hydrotreating reactions. After the hydrotreating reactions,the small and uniform Ni2 P particles were remained,although the CO uptakes on the used 60%Ni2P/Al2O3 and 80%Ni2P/Al2O3 were greatly decreased(to 68 and95 μmol/g,respectively) due to the incorporation of S into the Ni2 P surfaces. The 80%Ni2P/Al2O3 was found to be significantly more active than the 60%Ni2P/Al2O3 due to that the 80%Ni2P/Al2O3 possessed more,and more active Ni2 P sites than the 60%Ni2P/Al2O3,probably due to the less S incorporated in the 80%Ni2P/Al2O3 than in the 60%Ni2P/Al2O3 during the hydrotreating reactions. | Junen Wang Shaozhong Li Jun Xu Hui Chen Jiangyu Yuan Jianyi Shen | 2015 | Journal of Energy Chemistry2015，24，4： | 4 |
| 2 | Optimization of MgO/Al_2O_3 ratio for the maximization of active site densities in the Ni_2P/MgAlO catalysts for the hydrotreating reactions显示文摘The Ni_2P/MgAlO catalysts with different MgO/Al_2O_3 ratios were prepared by the phosphidation of corresponding Ni/Mg Al O catalysts with triphenylphosphine in liquid phase.It was found that the MgO/Al_2O_3 ratio affected the Ni_2P/MgAlO catalysts significantly.The Ni_2P/Mg Al O catalyst with the MgO/Al_2O_3 ratio of 3(w/w) exhibited the highly dispersed Ni_2 P particles(~9 nm) with the highest CO uptake(344 μmol/g)and thus the highest activities for the hydrotreating reactions.However,based on the CO uptakes on the used catalysts,the TOF values for the hydrodesulphurization of dibenzothiophene as well as those for the hydrogenation of tetralin on all the Ni_2P/MgAlO catalysts were respectively similar,indicating that the MgO/Al_2O_3 ratio did not affect the intrinsic activities of Ni_2 P supported on the MgAlO support for the hydrotreating reactions. | Junen Wang Xiaogan Wang Yamei Yuan Abdalla Shuaib Jianyi Shen | 2016 | Journal of Energy Chemistry2016，25，4： | 3 |

| 8 | Behaviors of helium in vanadium:Stability,diffusion,vacancy trapping and ideal tensile strength显示文摘The behaviors of helium in vanadium including stability,diffusion,and its interaction with vacancy as well as its effects on the ideal tensile strength was investigated by a frst-principles method.The activation energy barrier of helium was calculated to be 0.09 eV,which is consistent with the experimental result.The results indicated that the vacancy can lead to a directed helium segregation into the vacancy to form a helium cluster since the vacancy provides a 'lower atomic and electron density region' as a large driving force for helium binding.It is easy for a mono-vacancy to trap helium and form a Hen V complex.The frst-principles computational tensile test demonstrates that helium obviously decreased the tensile strength of vanadium. | Lijiang Gui Yuelin Liu Weitian Wang Yinan Liu Kameel Arshad Ying Zhang Guanghong Lu Junen Yao | 2013 | Progress in Natural Science:Materials International2013，23，5： | 0 |
