摘要
Tailoring metal oxide nanostructures with mesoporous architectures is vital to improve their electrocatalytic performance. Herein, we demonstrate the synthesis of 2D mesoporous Co3O4 (meso-Co3O4) 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-Co3O4 product. The optimized precursor concentration allows us to synthesize ordered meso-Co3O4 with four to seven nanowires in each particle. The meso-Co3O4 structure exhibits excellent electrocatalytic activity for both glucose and water oxidation reactions.
