Single-atom catalysts (SACs) have exhibited enormous potential toward electrocatalytic CO2 reduction (CO2RR). The accessibility of active sites has a significant influence on their catalytic performance, especially in the mass-transport-limited reaction like CO2RR. Therefore, rational design SACs with easily accessible and high-loading atomic is crucial but still remains grand challenge. In this work, thermally removable template strategy combined emulsion-induced interface anisotropic assembly method was developed to prepare iron single-atom catalyst easy high loading amount. For CO2RR, as-synthesized Fe-SACs supported hollow porous carbon nanocube (H–Fe–NC SACs) display selectivity CO. Most importantly, CO partial current density H–Fe–NC at −0.98 V can reach −23.5 mA cm–2, which 2.3 times higher than that solid sphere. matrix efficiently enhances promotes mass transport, thus accelerating kinetics catalysis reaction.
