Porous materials prepared by ultrasonic spray pyrolysis
Powders produced by ultrasonic spray pyrolysis (USP) are typically comprised of submicron, dense particles; however, depending on a material's applications, porous particles are more desirable. Here, porous particles are prepared using two newly developed templated aerosol methods. In the first approach, a sacrificial template is added to the precursor solution, allowing for composite formation via USP. Post-collection chemical treatment removes the template and introduces pores into the product particles. In the second approach, a temporary salt template is generated in situ which is then removed via aqueous workup
