Feel free to go through, our latest work on 6e-/6H+ catalytic CO2 reduction to CH3OH via a tandem approach.
Thrilled to share our latest @J_A_C_S. We show that unlike previous tandem CO2RR systems, a MOF-based molecular catalyst tandem utilizes a reaction intermediate other than CO (HCHO), and thus convert CO2 to Methanol. https://t.co/u6En4zR4U2 Congrats @ArnabGh29129499 @shiva2119!

#sabic2024 was a remarkable conference indeed. It was really overwhelming to interact with such renowned scientists all over the world, as well as felt honored to present my work in front of such distinguished bio-inorganic community. It is a reunion for #somadlab family as well.

Please check out our new work,,where the presence of 2nd sphere amine distal residues over porphyrin induces higher ORR rate at lower overpotential.
Just out @J_A_C_S now higher electrocatalytic rates can be obtained at lower driving forces using second sphere effects. https://t.co/mwcXIYkoRh

SO2 could be reduced to SO by an iron porphyrin via a [FeIII−SO]+ intermediate. This intermediate, which is proposed to be involved in sulfite reductase enzymes, has not been observed outside the...

2nd sphere hydrogen bond donors/proton transfer residues in iron porphyrins help substrate activation...ORR rates high selectivity high. Switch to hydrogen bond acceptors and you get product inhibition......ORR rate is slowed by 100 folds. https://t.co/pdHFBR79Ft
