My research interests include building and characterizing photocatalytic systems that couple light absorbing semiconductor nanocrystals to proton reduction catalysts. Using various time resolved and steady state spectroscopies we gain insight into the mechanisms governing the delivery of reducing electrons to the catalysts and use these insights to rationally optimize the photon to hydrogen conversion efficiency. We also exploit these photocatalytic systems as a novel method to optically initiate hydrogenase turnover, enabling time resolved investigation of the proton reduction mechanism via infrared spectroscopy which can be developed into a general methodology for probing catalytic reduction mechanisms.
