摘要： The present disclosure belongs to the technical field of catalyst preparation, and provides a polynorbornene/carbon black-cross-linked three-dimensional network-immobilized bimetallic copper/gold (PNBI/CB-Cu/Au) nanocatalyst, and a preparation method and use thereof. Metallic copper and gold both exist in a form of nanoparticles in the catalyst and are uniformly dispersed, and further enhancing a catalytic performance. Moreover, the carrier is a polynorbornene/carbon black-cross-linked three-dimensional network, and a relative content of free hydroxyl groups in the catalyst is controlled by changing a monomer ratio to adjust a hydrophilic-lipophilic balance value of the catalyst, adapting to a reaction of an organic phase with an aqueous phase. Furthermore, the catalyst is insoluble in conventional solvents, and has a desirable effect in immobilizing nanoscale metallic copper, prolonging a service life of the catalyst.

摘要： Disclosed is a process for the preparation of cis-1,1,1,4,4,4-hexafluoro-2-butene comprising contacting 1,1,1-trifluorotrichloroethane with hydrogen in the presence of a catalyst comprising ruthenium to produce a product mixture comprising 1316mxx, recovering said 1316mxx as a mixture of Z- and E-isomers, contacting said 1316mxx with hydrogen, in the presence of a catalyst selected from the group consisting of copper on carbon, nickel on carbon, copper and nickel on carbon and copper and palladium on carbon, to produce a second product mixture, comprising E- or Z—CFC-1326mxz, and subjecting said second product mixture to a separation step to provide E- or Z-1326mxz. The E- or Z-1326mxz can be dehydrochlorinated in an aqueous basic solution with an alkali metal hydroxide in the presence of a phase transfer catalyst to produce hexafluoro-2-butyne, which can then be selectively hydrogenated to produce Z-1,1,1,4,4,4-hexafluoro-2-butene using either Lindlar's catalyst, or a palladium catalyst further comprising a lanthanide element or silver.

摘要： A method of fabricating composite filaments is provided. An initial composite filament including a core and a cladding (such as a Pt-group metal) is cut into smaller pieces (or is first mechanically reduced and then cut into smaller pieces). The smaller pieces of the filaments are inserted into a metal matrix, and the entire structure is then further reduced mechanically in a series of reduction steps. The process can be repeated until the desired cross sectional dimension of the filaments is achieved. The matrix can then be chemically removed to isolate the final composite filaments with the cladding thickness down to the nanometer range. The process allows the organization and integration of filaments of different sizes, compositions, and functionalities into arrays suitable for various applications. Materials and components made from such composite filaments and arrays of composite filaments are also disclosed.

摘要： The present invention relates to a bimetallic catalyst for ammonia oxidation, a method for producing a bimetallic catalyst for ammonia oxidation and a method for tuning the catalytic activity of a transition metal. By depositing an overlayer of less catalytic active metal onto a more catalytic active metal, the total catalytic activity is enhanced.
