Abstract
Periodic mesoporous quartz was synthesized by a generally applicable nanocasting method at industrially achievable pressure (2–4 GPa) and temperature (750 °C) conditions. The materials have fcc lattice of interconnected spherical mesopores with diameters of ca. 15–18 nm, BET surface areas of 234–238 m 2 g −1, and pore volumes of 0.70–0.84 cm 3 g −1. They show exceptional hydrothermal stability of at least 800 °C in pure steam which appears suitable for practical applications in petroleum cracking.
