Abstract: A method for making a magnetic-nanoparticle-supported catalyst includes reacting a ferrocenyl phosphine compound with an amino alcohol compound to form a ligand having a phosphine group, an amine group and at least one hydroxyl group; anchoring the ligand to a surface of magnetic nanoparticles via an oxygen atom of the hydroxyl group to form a ligand complex; combining the ligand complex with a metal precursor comprising Rh to bind the metal precursor with the ligand complex and form the magnetic-particle-supported catalyst. The magnetic-particle-supported catalyst is a Rh complex of magnetic-Fe3O4-nanoparticle-supported ferrocenyl phosphine catalyst.

Abstract: The present invention provides a catalyst for catalytic reduction of an industrial flue gas SO2 with CO to prepare sulfur, a method for preparing the same and use thereof. A CeO2 nanocarrier is prepared by using a hydrothermal method, La and Y are loaded as active components, pre-sulfurization is conducted with 6% of SO2 and 3% of CO, and finally, the catalyst is prepared. The catalyst has high reactivity and sulfur selectivity and strong stability. The by-product sulfur generated by the reaction is recovered with a solvent CS2, and the solvent CS2 is recovered by using a distillation process. The preparation method is low in cost, causes no secondary pollution and is high in sulfur recovery rate. The problem of low sulfur production in China at present is solved.

Abstract: Proposed are a core-satellite micelle containing a tetra-block copolymer and a preparation method thereof. The core-satellite micelle includes a core, a shell surrounding the core, and a plurality of satellite domains positioned inside the shell. The core-satellite micelle contains a tetra-block copolymer represented by Structural Formula 1 below. The shell includes a first-monomer first block A1 and a first-monomer second block A2, and the satellite domain includes a second-monomer first block B1 and a second-monomer second block B2. The core-satellite micelle is foiled through self-assembly of the tetra-block copolymer, thereby having a larger interfacial contact area than existing block-copolymer micelles. Therefore, the core-satellite micelle can be used in next-generation nanotechnology applications such as drug delivery systems, porous catalyst materials, and sensors.

A1-B1-A2-B2  [Structural Formula 1]

In Structural Formula 1,



A1 is a first-monomer first block,
B1 is a second-monomer first block,
A2 is a first-monomer second block, and
B2 is a second-monomer second block.
