abstract = {Imposing phase engineering to porous materials is promising to realize outperforming electrocatalytic performances by taking advantages of the merits of porous nanoarchitecture and heterophase structure. In this work, amorphous/crystalline ruthenium oxide (RuO2) porous particles with rationally regulated heterophases are successfully prepared by integrating the phase engineering into the porous material synthesis. The resultant defect-rich amorphous/crystalline RuO2 porous particles exhibit excellent electrocatalytic performance toward the oxygen evolution reaction, achieving a low overpotential of 165 mV at a current density of 10 mA·cm−2 and a high mass activity up to 133.8 mA·cm−2 at a low overpotential of 200 mV. This work indicates that the synergistic effect of amorphous/crystalline heterophase and porous structural characteristics enables RuO2 to trigger a superior electrocatalytic activity.}
