Template-Free Single-Step Room-Temperature Fabrication of Metal Oxide Hollow Nanospheres and Nanofoams

摘要

Metal oxide hollow nanospheres and nanofoams are fabricated at room temperature by a single-step template-free aerosol process using low boiling-point hydrophobic solvent by controlling mass transport and sol-gel reactions at droplet interface. The facile technique is important for drug delivery, wave absorption, catalysts, sensors and energy storage.
