Ag-induced Phase Transition of Bi2O3 Nanofibers for Enhanced Energy Conversion Efficiency towards Formate in CO2 Electroreduction

Xin Wang et al.

Summary: In this study, an Ag-Bi2O3 hybrid nanofiber was developed for highly efficient electrochemical reduction of CO2 to formate. The Ag-Bi2O3 catalyst exhibited a formate selectivity of over 90%, and achieved a yield rate of 11.7 mmol·s(-1)·m(-2) at a current density of -250 mA·cm(-2). The presence of Ag in the catalyst increased the energy efficiency by nearly 10% compared to a Bi2O3 only counterpart, and this enhancement was attributed to the conversion of Bi2O3 from a monoclinic phase to a metastable tetragonal phase and the accelerated formation of active metallic Bi at low overpotentials.

Active and conductive layer stacked superlattices for highly selective CO2 electroreduction

Junyuan Duan et al.

Summary: This study proposes a superlattice model with alternating metal oxides and selenide sublayers, in which electrons are rapidly exported through the conductive metal selenide layer to protect the active oxide layer from self-reduction. The active [Bi2O2]2+ sublayers retain oxidation states during CO2 electroreduction due to rapid electron transfer through the conductive [Cu2Se2]2- sublayer. Theoretical calculations reveal high activity of the [Bi2O2]2+ sublayers, achieving over 90% formate selectivity. This work expands the understanding and improvement of CO2 electroreduction properties in metal oxide systems.
