Title

Hydrogen Sulfide Adsorption with Zinc Oxide Nano Materials

Abstract

Hydrogen sulfide (H2S) is a highly toxic gas that is produced in petroleum refining, natural gas, and the decomposition of sewage. Because of its increasing prevalence with today’s industrial processes, the need for competent filtration is eminent. A variety of metal oxides have been tested and used, such as zinc oxide (ZnO), as a filtering material. ZnO has a variety of structures it forms, and we are manipulating the synthesis and structure of ZnO to produce a highly efficient hexagonal nanoplate to adsorb the gas. By controlling several variables, such as temperature during the reaction between ZnO and H2S (g), length of exposure, and amount of adsorbent, we will determine the efficiency of the nanomaterials. So far we have found that our ZnO nanoplate material yields nearly 100% ZnS (s) while reacting with H2S (g) for 2 hours at 400 degrees Celsius.
