High temperature oxide melt solution calorimetry has been used to determine that the slight destabilization caused by the additional surface generated by the mesoporosity introduced in USY zeolite through surfactant‐templating (ca. 2 kJ mol −1 SiO 2 ) is significantly lower than the energetic stabilization resulting from surfactant–silica interactions (in the range of −6.0 to −12 kJ mol −1 SiO 2 ), which drives the rearrangement of the zeolite structure to produce the new hierarchical architecture.
