The Sayre Research Group designs and synthesizes broad-spectrum photocatalysts for high-energy reactions. We employ steady-state and time-resolved spectroscopy to investigate photocatalysis mechanisms. Mechanistic understanding informs design of the next generation of photocatalysts.
Broad-spectrum light absorption is important for the advancement of photocatalysis. Red photons are lower energy than blue photons and are lower cost. The sun is a sustainable source of broad-spectrum light.
Time-resolved spectroscopy is a valuable tool to learn how light-activated chemistry occurs. We use time-resolved spectroscopy to follow the flow of energy and electrons upon light absorption.
We use our understanding of photocatalysis mechanisms to minimize deactivation pathways such as charge recombination (CR).
The Sayre Group designs, synthesizes, and investigates light-activated catalysts to improve photocatalysis efficiency through mechanistic understanding. We investigate photocatalysis mechanisms using a variety of spectroscopic techniques and apply mechanistic insight to design the next generation of photocatalysis systems.
