Electron- and Photo-Induced Processes for Molecular Energy Conversion

Artificial Photosynthesis

Research Interests

Fundamental radiation chemistry of organic liquids, including the development of new radical scavengers. Photochemistry and radiation chemistry of transition metal complexes and other systems in conventional solvents, supercritical fluids, and ionic liquids, to gain a fundamental understanding of processes in solar fuels production and catalysis, e.g., CO2 reduction, H2 production, and small molecule activation. Development of advanced, nanosecond time-resolved infrared (TRIR) detection methods for pulse radiolysis and laser flash photolysis, and their use in mechanistic investigations of catalytic and other processes. Transient spectroscopic techniques (UV-visible and time-resolved infrared (TRIR)) on fast and ultrafast timescales.

I am also part of the Center for Hybrid Approaches in Solar Energy to Liquid Fuels (CHASE), which is a Department of Energy Fuels from Sunlight Hub. CHASE’s mission is to develop molecule/material (hybrid) photoelectrodes for cooperative sunlight-driven generation of liquid fuels from feedstocks found in air: CO2 and H2O. The Center is pursuing these goals through three interconnected Thrust areas: Thrust I: Catalyst-Semiconductor Interfaces; Thrust C: Cascades Catalysis, and Thrust H: Catalytic Hybrid Photoelectrodes. My involvement in CHASE includes the development of advanced surface-sensitive, infrared spectroelectrochemical methodologies for kinetic and mechanistic studies of molecular catalysts bound to semiconductor surfaces.
