Figure 1. Schematic illustration of the solid-liquid-gas triphase interface for thermally intensified CO2 electroreduction to formate. With the gas channel (red arrow) providing a sufficient supply to counteract the solubility-driven CO2 depletion in the liquid phase (blue arrow), the elevated temperature accelerates formate desorption (black arrow), synergistically ensuring the maximal utilization of thermal intensification strategies.
