Hierarchical copper oxide (CuO) microspheres were prepared by a simple microwave‐assisted preparation method in an ordinary household microwave oven under ambient pressure. The CuO microspheres were characterised by scanning electron microscopy, transmission electron microscopy, X‐ray diffraction, X‐ray photoelectron spectroscopy, and thermal gravimetric analysis. Characterisation results show that the hierarchical CuO microspheres are assembled by spine‐like nanorods and have high Brunauer–Emmett–Teller surface area of 25.0 m 2 /g.
