Hollow CuInS2microspheres have been successfully prepared via a simple solution-based route without employing templates and surfactants. Transmission electron microscope (TEM) images clearly show the hollow nature of the as-obtained products. Field emission scanning electron microscopy (FESEM) images reveal that the shells of as-prepared CuInS2microspheres were constructed by nanoparticles or nanoflakes. The specific surface area and pore-size distribution of the obtained product as determined by gas-sorption measurements show that the CuInS2hollow microspheres exhibit high Brunauer–Emmett–Teller (BET) surface area and porosity properties. TEM observations of intermediate products at different reaction stages indicate that these hollow CuInS2microspheres are formed mainly via Ostwald ripening.
