Research Overview

Design photocatalysts to improve efficiency and reactivity. Understand light-activated chemical reactions with time-resolved spectroscopy.

Sayre Research Group

The Sayre Group designs, synthesizes, and investigates light-activated catalysts (photocatalysts) with the goal of light-powered chemical manufacturing. We investigate photocatalysis mechanisms with spectroscopy and electrochemistry and apply mechanistic insight to improve photocatalyst efficiency.
