    摘要: The present invention relates unique pore structures in nickel supported on alumina with the negligible formation of macropores. Incorporation of additional elements stabilizes the pore structure of the nickel supported on alumina. Additional element(s) were then further added into the nickel-supported materials. These additional element(s) further stabilize the pore structures under heating conditions. The improvements of pore structure stability under heating conditions and negligible presence of macropores limit the sintering of nickel metal to a mechanism of impeded diffusion. The negligible presence of macropores also limits the deposition of alkali metal hydroxide(s)/carbonate(s) on the outer shell of the catalyst pellet in the molten carbonate fuel cells. Both the negligible presence of macropores and improvement in pore structure stability allow for prolonging the catalyst life of these nickel supported on alumina catalysts of the present invention for reforming hydrocarbons.

    摘要: The present invention discloses a method for producing carbon nanocoils, which comprises: providing a metal substrate; depositing a tin precursor on the substrate; heating the substrate with the precursor to a predetermined temperature to form a catalyst on the substrate; placing the substrate in a quartz tube furnace; and introducing carbon source gas and protective gas into the quartz tube furnace to allow carbon nanocoils to grow on the surface of the catalyst. Another method for producing carbon nanocoils is also disclosed, which includes: depositing a mixed solution of iron acetate and tin acetate on a substrate; heating the substrate with the mixing solution to a predetermined temperature to form a catalyst on the substrate; placing the substrate in a quartz tube furnace; and introducing carbon source gas and protective gas into the quartz tube furnace to allow carbon nanocoils to grow on the surface of the catalyst.
