Welcome to the Walter Research Group in the Department of Chemistry at the University of North Carolina at Charlotte. We are interested in the synthesis and development of new materials for solar energy conversion. Our work involves new porphyrin structures and photocatalytic materials for photovoltaic or solar fuel applications. We have recently begun to collaborate with researchers at the Carolina Medical Center to develop new sensitizers for photodynamic therapy. Our work spans materials research, organic synthesis, hybrid organic/inorganic systems, and nanoscience.

Congrats to the Walter Research Group for obtaining funding from the Environmental Protection Agency for a new project "Sustainable Responsivity" which is a collaboration with Prof. Mona Azarbayjani in the College of Architecture at UNC Charlotte. The design team composed of chemistry, physics, and architecture students will compete against other schools this March in Washington D.C. for the top P3 prize.

The lab is starting up! Our gloveboxes have been installed, and we are starting to synthesize and test new organic semiconductors. We will study their optical and electronic properties using organic polymer solar cell and photoelectrochemical configurations to learn about their ability to convert solar photons into usable, clean energy! Here's more picts of the Walter Lab.
