    摘要: The new metallocene catalysts according to the present invention are prepared by reacting a metallocene compound with a compound having at least two functional groups. The metallocene compound is a transition metal compound, which is coordinated with a main ligand such as cyclopentadienyl group, and an ancillary ligand. The functional groups in the compound are selected from the group consisting of a hydroxyl group, an alkyl or aryl magnesium halide, a thiol group, a primary amine group, a secondary amine group, a primary phosphorous group, a secondary phosphorous group, etc. The metallocene catalysts according to the present invention have a structure in which an ancillary ligand of a metallocene compound is bonded to the functional groups of a compound having at least two functional groups. A structure of the metallocene catalysts can be varied with the type of a metallocene compound and a compound having at least two functional groups, and the molar ratio of each reactant. The metallocene catalysts are employed with a co-catalyst for olefin polymerization. The co-catalyst is an organometallic compound, or a mixture of non-coordinated Lewis acid and alkylaluminium as it is well known in the art.

    摘要: The present invention relates to a method for preparing nanoporous carbons with enhanced mechanical strength and the nanoporous carbons prepared by the method, and more specifically, to a method for preparing a nanoporous carbon, comprising the steps of (i) synthesizing a mesoporous silica template not being subjected to any calcination process; (ii) incorporating a mixture of a monomer for addition polymerization and initiator, or a mixture of a monomer for condensation polymerization and acid catalyst into the as-synthesized mesoporous silica template, and reacting the mixture to obtain a polymer-silica composite; and (iii) carbonizing the polymer-silica composite at a high temperature to obtain a carbon-silica composite, from which the silica template is then removed using a solvent.According to the preparation method of the present invention, the nanoporous carbons having uniform size of mesopores, high surface area and high mechanical stability can be prepared at low preparation cost through a simplified preparation process. Therefore, the nanoporous carbons of the present invention can be used as catalysts, catalyst supports, separating agents, hydrogen reserving materials, adsorbents, membranes and membrane fillers in various application fields.
