Silica supported nanoparticles of nickel manganese oxide,
Ni0.2Mn0.8O, were prepared in a one-pot approach,
combining co-precipitation and sol–gel chemistry. This approach
enables the preparation of small ternary oxide crystallites evenly
dispersed on porous silica. The resulting materials were used as catalyst
for dry reforming of methane (DRM), and show a much higher activity
as the reference bulk material prepared from conventional co-precipitation.
Notably, the catalyst shows a remarkable activity even at low temperatures
for DRM, thus nearly reaching thermodynamic equilibrium at 500 °C.
