Continuous electrochemical reduction of carbon dioxide into formate using a tin cathode: Comparison with lead cathode

- The influence of key variables in a Sn cathode filter-press cell was studied.
- The performance of Sn plate was compared with previous results using Pb.
- As with Pb, the influence of current density using Sn was especially remarkable.
- Results with Sn plate cathodes outperformed those with Pb plate.
- These results reinforce the interest in Sn for CO2 electrovalorisation to formate.
