In collaboration with experimental groups at UCF, we have demonstrated that ammonium cations are more effective promoters of CO2 electroreduction (CO2RR) on Au in acidic media than Na+ and K+, achieving a 3-fold improvement in the CO2RR activity. Our Grand canonical Density Functional Theory (GC-DFT) simulations  reveal that promotional effect of NH4+ cations is attributed … Read more

We have uncovered a novel mechanism for CO₂ electroreduction (CO₂RR) to Formate on bismuth electrodes, which does not require CO₂ adsorption on the electrode surface. We also demonstrated the ability to control CO₂RR selectivity (Formate vs. CO) via cation in electrolyte. Notably, the presence of non-metal cations, such as CH₃NH₃⁺, enhances CO production as compared … Read more
