  In this talk,we present an efficient approach for finding the p smallest eigenvalues and their associated eigenvectors represented in a prescribed tensor-train(TT)format by solving the trace-minimization problem for a given a huge symmetric matrix A.

由于世界范围内石油资源的日益枯竭,采用煤、生物质等可替代资源通过甲醇生产乙烯、丙烯等低碳烯烃已经成为越来越重要的研究热点.由于分子筛可以催化甲醇转化成烯烃(MTO)同时甲醇具有来源广泛且价格低廉等优点,采用分子筛催化甲醇转化成烯烃受到了工业界以及学术界的广泛关注[1].
贵金属硫化物催化剂在选择性加氢反应中具有良好的选择性,近来受到众多关注,但是贵金属硫化物催化剂较低的催化活性导致需要较高的反应条件,而使其应用受到限制.本文采用H2S/H2混和气对Pd/C进行硫化处理,制备了具有核壳结构的PdSx@Pd/C催化剂,探讨了硫化温度、H2S/H2比等对PdSx@Pd/C催化剂结构的影响.对该系列催化剂进行了XRD、XPS、CO化学吸附等表征,结果表明H2S/H2比对催
