845CuS QDs/Co3O4 Polyhedra5nmTEMThe CuS QDs had a uniform distribution on the Co3O4 polyhedra surface (Figure 2A, B) with a diameter of 5 nm.The ZIF-67 exhibited a regular rhombic dodecahedral structure with a smooth surface over the whole particle and had an average size of 450 nm. The Co3O4 presented a very rough polyhedra shape, and the size average reduces to 300 nm due to the slight contraction caused by the calcination process.487.67
