3. Brief description of the Research Group
Our research group is focused on the development and application of advanced spectroscopic tools for the design of active catalysts for water oxidation, proton reduction, and methane to methanol production processes. Currently the development of artificial photosynthetic assemblies and biological mimics of naturally methane oxidizing enzymes is of great interest, and has drawn significant attention by exploring molecular catalysts based on 3d transition metal complexes. However in spite of emerging design principles, there is an urgent need to correlate the performance and stability of a catalyst to its geometric structure and electronic configuration for its rational development.

In this regard, we are interested in the development of static and time-resolved X-ray based spectroscopic approaches, including X-ray absorption (XAS) and X-ray emission spectroscopy (XES), to understand the critical electronic, energetic and geometric requirements of the water splitting and methane oxidation reactions necessary for achieving economically feasible catalysts. Our research is particularly oriented towards ultrafast pump (laser), X-ray probe studies of metal noble-free photosensitizers, and multimolecular photocatalytic systems for artificial photosynthesis in the femtosecond-microsecond time regime. Combined analysis of experimental data on structures, electronic configurations and spin states provide valuable information to understand the operation mechanism. Further selectivity is achieved through resonant XES or resonant inelastic X-ray scattering spectroscopy.

Synchrotron-based techniques employed in our group are complemented with laboratory- based spectroscopic methods such as UV-Visible spectroscopy, Resonance Raman, Electron Paramagnetic Resonance, Optical transient absorption spectroscopy, and Atomic Force Microscopy. Our studies involve the interplay of several disciplines including synthetic inorganic chemistry, electrochemistry, kinetics, and spectroscopy.

4. Project description


The project will consist in studying solar fuel catalysts through static and ultrafast in-situ X- ray spectroscopy and electrochemistry. The main objectives of the project will be to probe the electronic and structural changes occuring near the active catalytic site through X-ray absorption, emission and resonant inelastic scattering spectroscopy. The student will also be trained in Raman, EPR, Scanning Tunneling Microscopy and X-ray photoelecron spectroscopy.

The Ph.D student will assist in writing the beamtime proposals, and carrying out the synchrotron and laboratory-based experiments, data analysis and interpretation.

Required Qualifications:
1. M.S in chemistry, Physics or Biological Science
2. Experience in synthesis
3. Strong analytical skills, written and verbal communication skills

3. Brief description of the Research Group
Our research group is focused on the development and application of advanced spectroscopic tools for the design of active catalysts for water oxidation, proton reduction, and methane to methanol production processes. Currently the development of artificial photosynthetic assemblies and biomimetic mimics of naturally methane oxidizing enzymes is of great interest, and has drawn significant attention by exploring molecular catalysts based on 3d transition metal complexes. However in spite of emerging design principles, there remains a lack of general understanding about the structure-activity/stability relationship.

In this regard, we are interested in the development of static and time-resolved X-ray based spectroscopic approaches, including X-ray absorption and X-ray emission spectroscopy, to elucidate critical catalytic intermediates in solution phase and upon immobilization on electrode surfaces at synchrotrons. Combined analysis of experimental data on structures, electronic configurations and spin states provide valuable information to understand the operation mechanism. Further selectivity is achieved through resonant XES or resonant inelastic X-ray scattering spectroscopy.

Synchrotron-based techniques employed in our group are complemented with laboratory-based spectroscopic methods such as Raman, Electron Paramagnetic Resonance and Atomic Force microscopy and involve the interplay of several disciplines including synthetic inorganic chemistry, electrochemistry, kinetics, and spectroscopy.

4. Project description
The project will consist in studying artificial analogues of biological enzymes for dioxygen activation reactions through time-resolved X-ray absorption, emission and laboratory-based techniques with fs-ps temporal resolution. The main objectives of the project will be to explore the light-induced intramolecular electron transfer dynamics and kinetics to generate the active species responsible for the insertion of oxygen atom transfer in organic substrates.

The focus of the project will be based on synchrotron-based X-ray absorption and emission spectroscopy including valence-to-core XES, resonant XES, pump X- ray/probe laser spectroscopy and optical transient absorption spectroscopy. These studies will in the long term be complemented with studies at the X-ray free electron lasers and table top high harmonic sources.

The recruited postdoctoral fellow will assist in defining the study, writing the beamtime proposals, and carrying out the synchrotron and laboratory-based experiments, data analysis and interpretation.
