摘要：

In this work, ZnS microspheres consisting of nanoblocks were synthesized by a simple, templatefree approach employing a hydrothermal reaction at different temperatures, using Zn(CH3COO)(2) and Na2S2O3 center dot 5H(2)O as starting materials in the aqueous solution. The synthesized samples were characterized using field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and Brunauer Emmett Teller (BET). The photocatalysts were evaluated using photodecomposition of methylene blue under UV-C light. The photocatalytic degradation rate followed a pseudo-firstorder equation. The kinetic constant (k(1)) of the ZnS microspheres was 5.43 x 10(-2) min(-1).
