Project Description
Access to safe drinking water is considered a fundamental human right; when access is denied there are widespread health, education and economic implications that are exacerbated by rapid urbanization in developing nations. To address these problems, we are synthesizing a variety of heterogeneous hierarchical porous materials (high surface area materials with nanoscale active sites) for water treatment using novel greener processes. For this project, the student will fabricate an inexpensive, stable, reusable “foam” silicon bead dotted with zinc oxide (a photocatalyst) to degrade organic contaminants such as pharmaceuticals in water via sunlight. In a team of 2-3, students will fabricate and characterize zinc oxide nanoparticles, and then embed these nanoparticles in a foam made by sugar templating a silicon polymer. After characterizing its surface area and stability, the students will investigate the material’s ability to remediate water contaminated with organic compounds to propose a point-of-use device to address critical needs for safe drinking water in developing nations.

Students will learn a variety of materials fabrication and characterization techniques and analytical chemistry laboratory skills and will develop an understanding of photocatalysis for water treatment. Students with a background in Environmental or Chemical Engineering, Chemistry or Materials Science, will be best suited for this project. This project is open to teams of 2-3 students.
