AbstractRechargeable aqueous zinc-ion batteries (AZIBs), renowned for their safety, high energy density and rapid charging, are prime choices for grid-scale energy storage. Historically, ion-shuttling models centring on ion-migration behaviour have dominated explanations for charge/discharge processes in aqueous batteries, like classical ion insertion/extraction and pseudocapacitance mechanisms.

AbstractElectrochemical conversion of CO2 to formic acid using Bismuth catalysts is one the most promising pathways for industrialization. However, it is still difficult to achieve high formic acid production at wide voltage intervals and industrial current densities because the Bi catalysts are often poisoned by oxygenated species.

Graphical Abstract The Bi nanosheets with the edge defect sites coordinated with S via electrochemical reconstruction of Bi19Br3S27 nanowires (BBS), and the edge-sulfur modulated Bi catalyst demonstrates enhanced formate production and suppressed hydrogen evolution. In an alkaline electrolyte, the edge-sulfur modulated Bi nanosheets exhibit high current density (≈400 mA cm−2) and FE of HCOO− (>90 %) and very low FE of H2 (<5 %) over a wide potential range.
