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 (PtO2), and a third material (M3) such as a cerium oxide (CeOx). The shell can be formed of a ceramic such as silica and is generally a porous material that can support the yolk.
