Abstract |
The application of periodic anodic pulses in CO2 electroreduction (p-eCO2R) offers a promising route to counteract the inevitable in situ reduction of metal oxide catalysts. This study demonstrates the first application of p-eCO2R to a catalyst composed solely of a tin (oxide) active phase, using a pomegranate-structured SnO2@C nanosphere. Periodic, prolonged anodic pulses (30 s) at 0.2 V vs. RHE improved faradaic efficiency towards formate after 6 hours, retaining 78 +/- 2% versus 71 +/- 6% under potentiostatic conditions, suggesting p-eCO2R can extend Sn-based catalyst lifetimes for more sustainable CO2 conversion. |
