    摘要： An emission device is provided for extracting electrons onto an anode of a visual display. The emission device (10) includes a conductivity limited material (18) positioned between first and second electrodes (14, 16) and having a surface (26). A plurality of catalytic nanoparticles (22) are distributed throughout the conductivity limited material (18), wherein some of the catalytic particles (22) are contiguous to the surface (26). A plurality of nanostructures (24), such as carbon nanotubes, are grown from the catalytic nanoparticles (22) contiguous to the surface (26). A voltage is applied across the conductivity limited material (18) having a plurality of catalytic particles (22) embedded therein, thereby causing the electrons to tunnel between the catalytic particles (22). An anode (28) is spaced apart from the nanostructures (24) for extracting and receiving electrons emitted from the nanostructures (24) when a first potential is applied across the first and second electrodes (14, 16) and a second potential is applied to the anode (28).

    摘要： A method of forming a nano-supported sponge catalyst (10) on a substrate (12) is comprised of depositing an active catalytic metallic element (16) on the substrate (12) and depositing a structural metallic element (18) with the active catalytic metallic element (16) to form a mixed metal alloy layer (14). The method is further comprised of etching the mixed metal alloy layer (14) with an etchant to oxidize the active catalytic metallic element (16) and the structural metallic element (18) and to remove at least a portion of the structural metallic element (18) from a first sub-layer of the mixed metal alloy layer (14). The first sub-layer of the mixed metal alloy layer (14) is porous and comprised of nano-particles of the active catalytic metallic element (16) that are supported by a metal oxide structure derived from the structural metallic element (18).
