Clustered crystals of Silicalite-1 forming spherical-like structures were synthesized by a solvent-free solid-state method using activated carbon as a hard template. The influence of activated carbon dosage on the Silicalite-1 zeolite was explored by X-ray diffraction, specific surface area analysis, scanning electron microscopy, transmission electron microscopy, infrared spectroscopy, and X-ray photoelectric spectroscopy. The results show that the C—O—Si bond is formed between hydroxyl groups on the surface of activated carbon and silicic acid, growing and aggregating along the activated carbon and formed spherical-like Silicalite-1 zeolites after calcination. The spherical-like Silicalite-1 prepared with 10% (in mass fraction) activated carbon has a greater crystallinity with great specific surface area and pore volume as well as uniform particle size.
