Studies from B. Jeong et al Have Provided New Data on Photocatalytics (ZnO shell on mesoporous silica by atomic layer deposition: Removal of organic dye in water by an adsorbent and its photocatalytic regeneration)

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Photocatalytics have been published. According to news reporting from Yongin, South Korea, by NewsRx journalists, research stated, "We fabricated a ZnO shell on mesoporous Si02 (ZnO/Si02) particles with diameters of 250-500 pm using atomic layer deposition."

The news correspondents obtained a quote from the research, "This structure showed a higher adsorption capacity for methylene blue than bare mesoporous Si02. Moreover, the ZnO/Si02 saturated by methylene blue could be easily separated from the aqueous solution and regenerated upon UV exposure by the photocatalytic activity of ZnO for decomposing adsorbed methylene blue."

According to the news reporters, the research concluded: "This system can be used for efficiently removing organic pollutants from water by adsorption under dark conditions and photocatalytic regeneration, i.e., organic pollutants in water can steadily be removed under alternating dark-light conditions. ."
