摘要：

Highly porous ZnO monoliths are prepared with potential applications as regenerable adsorbents for sulfur removal. ZnS/NaCl composite materials are first obtained by combustion synthesis from mixtures of zinc, sulfur and sodium chloride powders. After NaCl removal by lixiviation with water, they are converted into ZnO by thermal treatment under air. The crystalline structure, the microstructure and the porosity of the resulting monoliths are investigated by X-ray diffraction, scanning electron microscopy and Hg porosimetry. Their evolution after sulfidation-regeneration cycles is also considered. (C) 2012 Elsevier B.V. All rights reserved.
