Water Chemistry meets Nanomaterials & Electrochemistry
The Greenlee Research Group
Welcome. Our group works on problems of societal importance at the nexus of water, food, and energy. We tackle science and engineering questions with expertise in water chemistry, electrochemistry, nanomaterials, and characterization tools. We invite you to explore our current research projects and think about how you look to solve the world’s problems.
Research Program Overview
Non-Precious Nanoparticle Electrocatalysts
Spectroscopic and electrochemical characterization of highly active electrocatalysts for the alkaline oxygen evolution reaction.
N & P Nutrient Recovery from Wastewater
In Situ Remediation of Harmful Algal Bloom Toxins
Polymer-supported photocatalysts are studied for the degradation of microsystin-LR, an HAB hepatotoxin, and the deactivation of cyanobacteria.
Remediation of Aquaculture and Irrigation Water
Flow-based electrochemical cell design and electrodeposited catalyst layers are used to remove nutrients and disinfect.
Water, Agriculture, Energy
Recovery of Water and Nutrients from Agricultural Wastewaters
Electrochemical cell design and electrodes are used to manage nutrients, treat wastewater, and understand energy efficiency and energy recovery.
Electrocatalyst Surface Chemistry and Double Layer Chemistry
Electrocatalyst films are studied to understand how oxide and hydroxide surface chemistry and the role of electrolyte cations affect electroreduction reactions.
Membrane Filtration to Recover N & P Nutrients
Membrane pore size and surface chemistry are studied to understand how membranes can be used to selectively recover nutrients.
Antimicrobial Membrane to Filter Wastewater
Polymer-2D nanomaterial composites are developed as membranes to provide an intrinsic antimicrobial activity and treat wastewater.
