Description
| This project deals with the use of metal-based fused diporphyrins as electrocatalysts for HER reduction. The objectives of the proposed work are as follows:
- Synthesis of metal complexes (Cu, Ni) of substituted free base monoporphyrin derivatives bearing hydrophilic groups at the periphery (-CO2CH3, tert-butyl groups).
- Synthesis of fused diporphyrins from respective monoporphyrin derivatives. Elucidation of their geometric and electronic structures through electrochemical, spectroscopic, and X-ray diffraction analyses.
- Evaluation of the catalytic activity of the metal complexes in HER reduction in non-aqueous mediums.
- Quantification of electrocatalytic efficiency, and elucidation of mechanistic pathway to develop structure-activity correlations.
- Elucidation of the mechanistic pathway to determine the active intermediates.
