Swellable Organically Modified Silica (SOMS) As a Catalyst Scaffold for Catalytic Treatment of Water through Hydrogenation and Hydrogenolysis Reactions Ozkan, Umit S.; Ailawar, Saurabh A.; Hunoor, Anagha; Çelik, Gökhan; Gunduz, Seval; Miller, Jeffrey T.; Tao, Franklin Feng; Edmiston, Paul L. (null; 2019-11-13) Ground water contamination by halogenated hydrocarbons or by aromatics is a growing concern. Existing technologies such as adsorption or air stripping suffer from incomplete degradation of the contaminants or their transfer from one medium to another such as water-to-land or water-to-air. In this study, we are investigating the catalytic conversion of these contaminants through catalytic hyrdogenolysis or hydrogenation reactions. What is unique about this study is that we are using a novel material, swellab...
Swellable Organically Modified Silica (SOMS) as a Catalyst Scaffold for Catalytic Treatment of Water Contaminated with Trichloroethylene Çelik, Gökhan; Sohn, Hyuntae; Tang, Yu; Tao, Franklin Feng; Miller, Jeffrey T.; Edmiston, Paul L.; Ozkan, Umit S. (2018-08-03) The properties of a swellable organically modified silica (SOMS) scaffold allowed us to synthesize "smart" catalysts with tunable accessibility of the active sites induced by organic swelling agents. Pd nanoparticles (NPs) deposited inside the swollen matrix of SOMS were shown to be selectively located on the interior surface, a surface which is only available through swelling. Techniques such as near ambient-pressure X-ray photoelectron spectroscopy (NAP-XPS) and cryogenic scanning electron microscopy (SEM...
Swellable Organically Modified Silica (SOMS): A Novel Support for Pd Catalyzed Hydrodechlorination of Trichloroethylene in Aqueous Phase Çelik, Gökhan; Gunduz, Seval; Miller, Jeffrey T.; Tao, Franklin Feng; Edmiston, Paul L.; Ozkan, Umit S. (null; 2018-10-28)
Swellable Organically Modified Silica (SOMS): A Novel Support for Aqueous Phase Hydrodechlorination of Trichloroethylene Ailawar, Saurabh A.; Çelik, Gökhan; Hunoor, Anagha; Gunduz, Seval; Edmiston, Paul L.; Ozkan, Umit S. (2019-06-28) This study focuses on the use of swellable organically modified silica (SOMS) as a catalyst support for aqueous-phase hydrodechlorination of trichloroethylene. SOMS is extremely hydrophobic and swells volumetrically when contacted with organics. These properties should help overcome the disadvantages associated with the commercial catalyst (Pd/Al2O3), such as deactivation by anions.
