Molecular Heterogeneous Catalysis in Confined Geometries
Metal complexes of porphyrinoids and pyridyl-carbenes as molecular photo-/electro-catalysts in confined geometries
Sequestering climate-unfriendly CO2 and utilizing it to generate useful chemicals is one of the grand challenges of the current age. One of the possible strategies to this end is the electrocatalytic reduction of CO2. However, this usually gives CO or formate as end products, which have limited value. Hence, there is a need for developing processes that lead to C2 and higher products. In this project, we will develop and immobilize well-defined molecular catalysts in mesoporous materials to improve the CO2 reduction reaction (CO2RR) by: i) preconcentrating CO2, ii) improving selectivity for CO2RR over hydrogen production and for C≥2 over C1 products.
