Hydrogen Sulfide Removal Using Zinc Oxide Nanoplates
Hydrogen sulfide (H2S), a dangerous and highly toxic gas, is formed through many industrial processes (most notably waste treatment, sewage treatment, and oil refining). Due to the prevalence and toxicity of the gas, members of these industries need to remove hydrogen sulfide as they complete their respective industrial processes. Zinc oxide (ZnO) can be used in this removal. Zinc oxide and hydrogen sulfide react to form zinc sulfide (ZnS) and water. The structure of the zinc oxide differs significantly based on the method of synthesis. The structure greatly affects the ability of the zinc oxide to react with hydrogen sulfide. Other variables that can affect the reaction include temperature, H2S gas flow rate, and zinc oxide grain size. Our research has shown that the zinc oxide nanoplates can reach 95% theoretical sorption. Our nanoplates have shown 10-15% superiority to commercially available nanoparticles.
