Mapping Electron Flux in Biomimetic Catalysts for Artificial Photosynthesis


EMSL Project ID
51221

Abstract

This proposal requests computational resources to support the Open Call LDRD “Artificial Photosynthesis with Next Generation Molecular Catalysts” (Wiedner). This research program focuses on the development of a new class of biomimetic molecular photocatalysts for CO2 reduction that will enable breakthrough advances in artificial photosynthesis. The central hypothesis is that the electron flux in artificial photosynthetic systems can be directed towards productive conversions using bimetallic catalysts in which the reduction potential can be controlled independently of the catalytic rate. To test our hypothesis, we will focus on two specific aims: (1) accurate calculation of the reduction potentials of the different catalyst intermediates, and (2) studying the electron transfer dynamics between the catalyst intermediates and the photosensitizer that harvests the photons using to provide the catalytic driving force.
