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

Our research activities include laboratory and field studies on wastewater treatment, water treatment, nutrient recovery, and electrochemical and electrocatalytic processes. We conduct experiments focused on electrode engineering, nanomaterials synthesis, chemical and morphological characterization, and (electro)catalyst materials performance.

Water

How can we utilize materials science and engineering technology to enable water sustainability?

Food

What are the water and energy challenges for food production, and how can we use engineering to support a resilient food supply?

Energy

How can we use materials and system design to achieve energy efficiency?

Research Program

Energy

Non-Precious Nanoparticle Electrocatalysts

Spectroscopic and electrochemical characterization of highly active electrocatalysts for the alkaline oxygen evolution reaction.

Water

N & P Nutrient Recovery from Wastewater

Electrochemical technology designed and studied for the recovery of nitrogen and phosphorus in recyclable forms.

Water

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.

Agriculture

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.

Energy

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.

Water

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.

Water

Antimicrobial Membrane to Filter Wastewater

Polymer-2D nanomaterial composites are developed as membranes to provide an intrinsic antimicrobial activity and treat wastewater.
