Abstract: The present disclosure relates to yolk-shell structured catalysts. The yolk-shell catalysts can be particularly useful in the tri-reforming of methane. The yolks can include a primary material (M1), such as nickel (Ni) or nickel oxide (NiO), and a secondary material (M2). The shell is generally a porous material that can support the yolk. The shell can include silica (SiO2) and the secondary material can include ceria (CeO2). The yolk-shell catalyst can take the form of tube-like structures in which the yolk is dispersed within the shell support in a substantially homogeneous fashion.

Abstract: 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.
