Research Description

The Baber Lab uses ultrahigh vacuum surface science studies to simplify complex catalytic materials to better understand reaction pathways and active sites. Our research utilizes a home-built surface analysis chamber to run temperature programmed desorption and Auger electron spectrometry experiments. We also use atomic force microscopy to characterize the morphology of our surfaces.
