Abstract :
Octahedral Co3O4 (~1 μm) was synthesised by a one-step carbon-assisted method using degreasing cotton and cobalt chloride as precursors. The characterisation results show that the calcination temperature, calcination time, reaction precursor, oxygen environment and reactants ratio of the precursor play important roles in fabricating the Co3O4 powders. The result of the UV-vis spectrum also shows that the octahedral Co3O4 obtained can be applied in photocatalytic water splitting under visible light irradiation.
