Convergence Research Seminar Series, William Tarpeh, PhD (Stanford University)

Abstract:

Wastewaters are underutilized mines that can improve the sustainability of chemical manufacturing. Converting aqueous pollutants into high-purity products require both separations and reactions with high selectivity. These ion-selective separations require integrated design of materials and processes, particularly electrochemical separations and electrocatalysis that can be paired with renewable energy and on-site manufacturing. This seminar will focus on converting wastewater nitrate to ammonia and concentrating ammonia as a value-added product using electrocatalysis and electrochemical swing processes. Together, these efforts to design nitrogen-selective electrochemical processes will enable treatment of polluted waters and electrified chemical manufacturing.
