Tailoring metal oxide nanostructures with mesoporous architectures is vital to improve their electrocatalytic performance. Herein, we demonstrate the synthesis of 2D mesoporous Co 3 O 4 ( meso ‐Co 3 O 4 ) nanobundles with uniform shape and size by employing a hard‐template method. In this study, the incipient wetness impregnation technique has been chosen for loading metal precursor into the silica hard template (SBA‐15). The results reveal that the concentration of a saturated precursor solution plays a vital role in mesostructured ordering, as well as the size and shape of the final meso ‐Co 3 O 4 product. The optimized precursor concentration allows us to synthesize ordered meso ‐Co 3 O 4 with four to seven nanowires in each particle. The meso ‐Co 3 O 4 structure exhibits excellent electrocatalytic activity for both glucose and water oxidation reactions.
