    摘要:
    研究了钠(Na)促进剂对钴锰(CoMn)催化剂对费托合成烯烃(FTO)反应的催化性能的影响。对于不含Na的样品,发现Co 0是具有低CO 2选择性的传统基于Co的费-托反应的活性相。发现烯烃/石蜡(O / P)比率低,C 2-4 =选择性仅为15.4 C%。然而,通过添加Na,形成了暴露出(101)和(020)小面的碳化钴(Co 2 C)四边形纳米棱镜。Co 2 C纳米棱镜显示出较高的C 2–4 =在温和的反应条件下具有较高的选择性(54.2 C%)和较低的甲烷选择性(5.9 C%)。C 2–4的O / P比达到23.9,并且产品分​​布与经典的Anderson–Schulz–Flory(ASF)分布大相径庭。Co 2 C纳米棱镜被认为是一种有效的FTO活性相,具有很强的刻面效应。Na促进剂在FTO催化剂的发展中起关键作用。Na作为钴的电子供体,添加后会导致更强的CO吸附和增强的CO解离,这也有利于Co

    A series of Mn–Co mixed oxides with a gradual variation of the Mn/Co molar ratio were prepared by coprecipitation of cobalt and manganese nitrates. The structure, chemistry, and reducibility of the oxides were studied by X-ray diffraction (XRD), X-ray absorption spectroscopy, X-ray photoelectron spectroscopy (XPS), and temperature-programmed reduction (TPR). It was found that at concentrations of Mn

    Thin metallic Mn 50 Co 50 coatings (0.3 and 1 μm) were deposited by magnetron cosputtering on bare and on 100 h preoxidized ZMG232L stainless steel substrates for application as protective coatings for solid oxide fuel cells (SOFCs) interconnects. The coatings on bare steel were oxidized for different times of up to 101 h at 800°C in ambient air. After 1 h heat-treatment, the metallic films had already

From the results on Co/Cr and Co/Ru multilayers it is deduced that the impurity neighbours out of the c-plane depress the Co hyperfine field less than the in-plane impurity neighbours. Comparison with the alloys CoCr and CoRu suggests a similar conclusion for CoMn alloys. As to CoCu systems, the situation is the opposite, although there

  • Structure and magnetism of the β-Mn–Co solid-solution phase

    The crystal structure of the beta-Mn1-tCot solid-solution phase (0 <= t <= 0.40) has been studied with powder neutron (10 and 298 K) and single-crystal X-ray (150 K) diffraction methods. The lattice-constant (a) isotherms at 10, 150, and 298 K go through flat maxima between t = 0.10 and 0.25. Up to t = 0.25 all Co is found to substitute at the T1 (T1 = Mn and/or Co) site of the beta-Mn crystal structure (position 8c of space group P4(1)32) whereas for t = 0.40 also the T2 site (position 12d) is partly occupied by Co (some 0.2 Mn + 0.8 Co occupancy of the T2 site). The variable positional parameters x (for T1) and y (for T2) exhibit remarkably small variations with composition (t) and temperature. The present low-temperature powder neutron-diffraction data confirm the earlier finding that the beta-Mn1-tCot phase does not exhibit conventional co-operative magnetic ordering. However, the appearance of diffuse scattering in the low-temperature diffraction patterns is clearly generated by short-range ordering of magnetic moments, which owing to the atomic arrangement of the beta-Mn-type structure becomes geometric frustrated. The temperature dependence of the magnetic susceptibility for beta-Mn1-tCot is re-measured. Neglecting beta-Mn itself (which exhibits virtually temperature-independent paramagnetism), our magnetic susceptibility curves above some 80 K for t = 0.15, 0.25, and 0.40 can with good-will be described by the Curie-Weiss relation, indicating antiferromagnetic correlations at low temperatures. However, the thus involved paramagnetic moments and Weiss constants must indeed be stamped as unphysically large. (C) 2008 Published by Elsevier B.V.
