Low‐dimensional copper selenide (Cu 2‐ x Se) nanostructures with controllable morphologies are fabricated via the chemical synthesis. The ratio of reactants and the concentration of ligands affect the kinetics of the transformation reaction and control the morphology of Cu 2‐ x Se nanostructures. The resultant Cu 2‐ x Se nanostructures are valuated as potential electrocatalysts for oxygen reduction reaction (ORR) in alkaline media at room temperature. The electrocatalytic activity of the Cu 2‐ x Se nanorods is better than that of other nanostructures. The type and amount of carbon materials mixed with Cu 2‐ x Se nanorods influence the catalytic performance of the modified electrodes. This study illustrates that the low‐dimensional Cu 2‐ x Se nanostructures can perform as electrocatalysts for ORR in alkaline media.
