Silicalite-1 (S1) foam was functionalized by supporting manganese-cobalt (Mn-Co) mixed oxides to develop the structured hierarchical catalyst (Mn-Co@S1F) for catalytic combustion for the first time. The self-supporting S1 foam with hierarchical porosity was prepared via hydrothermal synthesis with polyurethane (PU) foam as the template. Subsequently
Mn-Co oxide nano sheets were uniformly grown on the surface of S1 foams under hydrothermal conditions to prepare the structured hierarchical catalyst with specific surface area of 354 m

the crushed Mn-Co@S1F) and unsupported Mn-Co oxides (
i.e
.
Mn-Co). Mn-Co@S1F exhibited comparatively the best catalytic performance
that is
complete and stable toluene conversion at 248 °C over 65 h due to t
he synergy between Mn-Co oxides and S1 foam
which provided a large number of oxygen vacancies
high redox capacity. In addition
the hierarchical porous structure also improved the accessibility of active sites and facilitated the global mass transfer across the catalyst bed
being beneficial to the catalysis and catalyst longevity.
