Catalysts, catalyst precursors, and catalytic systems are provided. The catalysts generally comprise a substrate that includes a group IB metal and a porous, microcrystalline layer that includes the metal and that is disposed on at least a portion of the substrate. The catalysts are prepared by providing a substrate that includes group IB metal, oxidizing said substrate in the presence of stainless steel to produce an oxide coating of said group IB metal, and reducing substantially all of said oxidized substrate.
