Abstract Boron‐doped carbon nanocage (BC‐2) was used as carrier to anchor palladium nanoparticles and enhanced the catalytic performance for the ethanol oxidation reaction. The BC‐2 was synthesized via thermal treatment the predesigned compound containing cobalt and boron at 900 °C with the help of hydrogen and acid washing process. Palladium nanoparticles can be loaded on the BC‐2 supports (Pd/BC‐2) for ethanol oxide reaction (EOR). The BC‐2 support has the following characteristics: (i) The hollow structure contains highly order nanoporous to offer more channel and space in catalysis process; (ii) boron‐doped carbon structures can supply abundant activity sites for stabilizing palladium nanoparticles; (iii) the unique three‐dimensional architecture can prevent the agglomeration and inactivation of metal catalysts. The Pd/BC‐2 catalyst displays higher catalytic activities 3614.11 mA mg −1 toward the peak current density compared to that of Pd/C (804.39 mA mg −1 ).
