Copper-based nano/microparticles have recently triggered much research interest for the development of low-cost and high-performance catalysts that have industrial applications. However, oxidation of Cu to CuO is a commonly observed phenomenon when the sample is handled under ambient conditions. In this work, we reported an aqueous-phase synthesis of hybrid metal–semiconductor Cu-Cu2S microparticles by using Cu microplates templates in a rapid surface sulfidation process while preventing the quick oxidation of Cu monometallic microparticles. The morphology and structure of hybrid Cu-Cu2S were characterized by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. The presence of metal and semiconductor in these hybrid structures contributes to improve the photocatalytic properties due to the synergistic effects between the two components. |
