A novel method to produce a hierarchical porous carbon as a conductive support of PtRu particles. Effect on CO and methanol electrooxidation

► A novel and simple method for the synthesis of hierarchical porous carbon (HPC) is reported. ► The carbon present macropores and mesopores with large active surface area. ► Highly disperse PtRu nanoparticles are loaded inside the HPC by modifying the formic acid method. ► This hierarchical porous catalyst shows high activity toward methanol electrooxidation.
