The XRD, HRTEM, and N2 adsorption-desorption isotherms were used to characterize the prepared ZnO functionalized mesoporous silica samples. As a result, the presence of ZnO in highly-ordered MCM-41's pore was proved as well as maintenance of the ordered mesostructure of MCM-41. The materials were possessed with a high specific surface area (1114-509 m2.g-1) and a large pore diameter (4.03-3.27 nm). Based on the obtained results from the adsorption of H2S gas in a lab-made setup, the Znx@MCM-41 showed the superior ability to increase of ZnO amount up to 7 hours as a breakthrough point.  06 29 2020 74 81 10.24200/amecj.v3.i02.104 http://journal.amecj.com/index.php/AMECJ-01/article/view/104 http://journal.amecj.com/index.php/AMECJ-01/article/download/104/207 http://journal.amecj.com/index.php/AMECJ-01/article/download/104/207 http://journal.amecj.com/index.php/AMECJ-01/article/download/104/208
