Thin layers of silicalite‐1 were grown on H‐ZSM‐5 crystals. Silicalite‐1 crystals of < 100 nm formed on the ZSM‐5 crystals and grew along the crystal surface (see Figure). The single‐crystal‐like composite catalyst showed excellent para‐selectivity of 99 % in the alkylation of toluene with methanol, and is expected to develop as a new shape‐selective catalyst.
