This National Science Foundation (NSF) CAREER award under the Engineering (CFDA 47.041) program provides $440,000 in funding to The Leland Stanford Junior University (Stanford University) over the period of May 1, 2024 to April 30, 2029. The project's overarching goal is to explore the use of electrochemical refining to recover nitrate from wastewater and convert it into valuable products like ammonia, a critical component of nitrogen fertilizers. The key objectives are to: 1) design and synthesize novel molecular electrocatalysts to enable efficient and selective electrochemical nitrate reduction to ammonia, 2) develop extraction systems to separate the catalysts and ammonia products from treated wastewater, and 3) optimize integrated electrochemical reactor and separation systems that could be integrated into wastewater treatment plants. This work aims to advance the mitigation of nitrate pollution and enable a more sustainable circular nitrogen economy. The project also includes educational and outreach activities such as an electrochemistry bootcamp, undergraduate research opportunities, and science fair projects to engage students from underrepresented groups.
