Abstract
Abstract A Raney metal catalytic sheet material is prepared by spraying molten particles of a Raney alloy, such as a silver, nickel, iron, platinum or cobalt alloy with aluminum on a substrate, and leaching aluminum from the alloy. The sheet catalyst is claimed as is the process of manufacture.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
43 words
A self-supporting porous Raney silver electrode in sheet form according to claim 1, wherein said electrode has a thickness between about 0.5 mm. and 2 mm. and comprising a continuous porous layer consisting essentially of highly subdivided particles of Raney silver bonded together.
Claim 2
Dependent Claim
57 words
A composite Raney silver electrode in sheet form according to claim 1, wherein the electrode comprises a substrate coated with between 0.1 mm. and 1.5 mm. of Raney silver, said Raney silver being in the form of a continuous porous layer consisting essentially of highly subdivided particles bonded together to form sheet material capable of being self-supporting.
Claim 3
Dependent Claim
41 words
Sheet material suitable for electrodes comprising a continuous porous layer consisting essentially of highly subdivided particles of Raney nickel bonded together to form sheet material capable of being self-supporting, said Raney nickel being slightly oxidized to render said sheet material nonpyrophoric.
Claim 4
Dependent Claim
43 words
A self-supporting porous Raney nickel electrode in sheet form according to claim 4 wherein said electrode has a thickness between about 0.5 mm. and 2 mm. and consisting essentially of a continuous porous layer of highly subdivided particles of Raney nickel bonded together.
Claim 5
Dependent Claim
43 words
A composite porous Raney nickel electrode in sheet form according to claim 4 wherein said electrode comprises a continuous porous layer consisting essenTially of highly subdivided particles of Raney nickel bonded together and bonded to and supported by a porous sheet nickel substrate.
Claim 6
Dependent Claim
49 words
A composite Raney nickel electrode in sheet form according to claim 4 wherein said electrode comprises a substrate coated with between 0.1 mm. and 1.5 mm. of Raney nickel, said Raney nickel being in the form of a continuous porous layer consisting essentially of highly subdivided particles bonded together.
Claim 7
Dependent Claim
12 words
The composite electrode of claim 7 wherein said substrate is nickel foil.
Claim 8
Dependent Claim
54 words
A composite Raney nickel electrode in sheet form according to claim 4 wherein said electrode comprises a nickel foil substrate coated on both surfaces with between 0.1 mm. and 1.5 mm. of Raney nickel, said Raney nickel being in the form of a continuous porous layer consisting essentially of highly subdivided particles bonded together.
Claim 9
Dependent Claim
42 words
Sheet material suitable for electrodes comprising a continuous porous layer consisting essentially of highly subdivided particles of Raney cobalt bonded together to form a sheet material capable of being self-supporting, said Raney Cobalt being slightly oxidized to render said sheet material nonpyrophoric.
