权利人:UNIV NANYANG TECH
摘要:Methods of preparing a sulfur-containing catalyst for the chirally selective synthesis of single-walled carbon nanotubes are presented. Sulfur-containing catalysts for the chirally selective synthesis of single-walled carbon nanotubes, the catalysts comprising sulfur-doped transition metal as active phase on a support, and methods of forming single-walled carbon nanotubes having a selected chirality using the catalysts are also presented.

权利人:WESTAIM TECHNOLOGIES INC
摘要:A single calcination stage process for the synthesis of homogeneous crystalline lithium nickel cobalt dioxide from either a mechanical mixture of nickel and cobalt oxides, hydroxide or oxyhydroxide or a chemical precipitation of a homogeneous nickel cobalt hydroxide or cobalt nickel cobalt oxyhydroxide is provided. The reactants are calcined in the presence of lithium hydroxide and an alkali metal hydroxide under predetermined oxygen partial pressure and temperature conditions. The products of the process are characterized in having a lithium to transition metal ratio closely approximating to the desired theoretical value.

摘要:The present invention is related to a cobalt catalyst supported on high-surface area niobium pentoxide for Fischer-Tropsch synthesis, the support of this catalyst which is a niobium pentoxide (Nb2O5) with a BET surface area in the range of 30 to 160 m2.g-1, the process for the preparation of the high-surface area support of niobium pentoxide by calcination of a hydrated niobium oxide or by synthesis from either organic or inorganic niobium precursors, a process for the preparation of said catalyst, and the use of the catalyst for the Fischer-Tropsch synthesis to obtain hydrocarbons with carbon atoms equal or higher than five containing specially linear paraffins in the diesel fuel range, and without a significant formation of light hydrocarbons, olefins, aromatics and oxygenated compounds.

摘要:Disclosed is a new catalyst composition comprising a bimetallic Co—Fe catalyst, optionally complexed with a ligand selected from a N-heterocycle, phosphine, or porphorine ligand, that provides a lower cost alternative for the one step synthesis of 1,3-propanediol (1,3-PDO) from ethylene oxide and synthesis gas. For example, a catalyst containing cobalt carbonyl: iron carbonyl with no ligand, or a catalyst containing a cobalt carbonyl: octaethylporphine iron acetate provide moderate yields of 1,3-PDO in a one step synthesis under mild conditions.

摘要:Disclosed is a new catalyst composition comprising a bimetallic Co—Ru catalyst complexed with a N-heterocylcic ligand that is effective, economical, and provides improvements in oxidative stability in the one step synthesis of 1,3-propanediol (1,3-PDO) from ethylene oxide and synthesis gas. For example, cobalt-ruthenium-2,2′-bipyrimidine, 2,2′-dipyridyl, or 2,4,6-tripridyl-s-triazine catalyst precursors in cyclic ether solvents, such as 1,3-dioxolane, 1,4-dioxolane, 1,4-dioxane, and 2-ethyl-2-methyl-1,3-dioxolane, provide good yields of 1,3-PDO in a one step synthesis.

摘要:A method for the fabrication of nanostructured semiconducting, photoconductive, photovoltaic, optoelectronic and electrical battery thin films and materials at low temperature, with no molecular template and no organic contaminants. High-quality metal oxide semiconductor, photovoltaic and optoelectronic materials can be fabricated with nanometer-scale dimensions and high dopant densities through the use of low-temperature biologically inspired synthesis routes, without the use of any biological or biochemical templates.
