High activity platinum and nickel yolk-shell catalysts
The present disclosure relates to yolk-shell structured catalysts having compositions that can be particularly useful in the dry reforming of methane. These catalysts can demonstrate long-term stability that would be an advantage in industrial applications such as mitigating fossil fuel plant emissions. Example catalysts can include a yolk containing nickel (Ni) or nickel oxide (NiO), platinum (Pt) or platinum oxide (PtO.sub.2), and a third material (M3) such as a cerium oxide (CeO.sub.x). The shell can be formed of a ceramic such as silica and is generally a porous material that can support the yolk.

Process for reducing aromatic nitro compounds with supported catalyst
A supported catalyst having rhodium particles with an average diameter of less than 1 nm disposed on a support material containing magnetic iron oxide (e.g. Fe.sub.3O.sub.4). A method of producing the supported catalyst and a process of reducing nitroarenes to corresponding aromatic amines employing the supported catalyst with a high product yield are also described. The supported catalyst may be recovered with ease using an external magnet and reused.
