Positioning growth of scalable silica nanorods on the interior and exterior surfaces of porous composites

摘要: A novel yet straightforward one-pot synthesis technique was developed to grow silica nanorods on the interior and exterior surfaces of a porous, inorganic scaffold. Growth rods surface, versus in bulk, achieved by functionalizing surface with chlorosilane molecules, which allowed emulsion droplets anchor surface. Rods 100–200 nm diameter up 2 μm length could be grown uniformly over typical density 3 per μm2, resulting an order-of-magnitude increase specific area (area mass) porous material. It also shown that properties (e.g., size, density, shape) controlled changing either composition substrate material or concentrations key components reacting mixture. Furthermore, selectively controlling spatial location groups, locations inside
