(514g) High Temperature Catalyst Development and Testing for Low Cost and Efficient Solar Driven Sulfur-Based Hydrogen Production
Greenway Energy (GWE), in conjunction with the University of South Carolina (USC) and Idaho National Laboratory (INL), is developing and testing new catalytic materials to decompose sulfuric acid. A novel catalyst preparation technique, developed by USC, uses a combination of: (1) strong electrostatic adsorption (SEA), which permits formation of very small metal particles with a narrow distribution of sizes, and (2) electroless deposition (ED) to produce controlled bimetallic catalysts. This will result in limiting the catalyst deactivation by using very small particles of a high surface free energy core metal with a catalytically-active outer metal shell deposited by ED. This presentation will focus on the testing of these novel catalysts in the high-temperature sulfuric acid decomposition environment.
