This research project, supported by the Analytical and Surface Chemistry Program and the Grant Opportunities for Academic Liaison with Industry (GOALI) program, addresses the molecular level mechanisms of the direct synthesis of silicone precursors from silicon using copper catalysts, the Muller-Rochow process. The research combines UHV adsorption studies carried out at Temple University under the direction of Professor Strongin, with STM measurements of the reactant surface carried out by Professor Hinch and coworkers at Rutgers University. Scientists at Dow Corning Corporation are involved in the evaluation of reaction kinetics and selectivity of the catalysts designed by the group based on the results of the molecular level investigations of reaction mechanism. Understanding gained from these studies is applied directly in the predictive design of catalysts for the Muller-Rochow process. The information gained from this work will have a direct impact on the commercially important silicones industry. The investigation of the molecular level mechanism of the direct synthesis of silicone precursors on Cu/Si surfaces is the focus of this research project. A combination of basic studies of copper catalyzed adsorption, morphological studies of the reacting silicon surface, and kinetic studies of operating catalysts will provide information about this technologically important process. Researchers at Temple University, Rutgers University, and the Dow Corning Corporation all contribute to this research project.
