Abstract: A selective postsynthetic surface modification process of mesoporous Y zeolite (Meso-Y) is provided. The process results in a thin silica, alumina or aluminosilicate overlayer on the external surface without causing significant pore blockage, which otherwise results in the absence of surfactant. The approach relies on occluded CTAB surfactant in as-synthesized Meso-Y acting as a soft template, which protects internal microporosity and mesoporosity during inorganic overlayer synthesis, by directing its deposition to selectively occur on the external surface. The process is conducted under dry conditions.
