These pollutants are removed by heterogeneous catalysis and the platinum group metals (PGM) remain the catalysts of choice but this situation is now complicated by the requirement for higher performance at lower costs while the PGM are experiencing escalating prices. A solution to this problem is the use of nanostructured perovskite-based Nanoxite™ catalysts engineered with unique structural features and high surface areas that enable higher catalytic efficiency at lower temperatures without sacrificing durability performance. In fact, Nanoxite is a “catalytic washcoat” product in that it simultaneously functions as the emission control catalyst while providing the bulk of the washcoat. As a result, both the PGM level and the amount of conventional washcoat materials are simultaneously reduced. Each powder particle possesses a hierarchical structure where larger micron sized particles hold the < 40 nanometer size perovskite grains. This desired arrangement facilitates easy powder handling and eliminates reactivity typically associated with discrete Nanograin materials. These perovskite-based catalyst formulations are applicable to both diesel engine and stationary emission control with respect to CO / VOC oxidation and the management of NOx and PM.","PeriodicalId":6429,"journal":{"name":"2007 Cleantech Conference and Trade Show Cleantech 2007","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2006-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73383048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These novel materials are created from a combination of synthetic nanoporous ceramic substrates that have specifically tailored pore sizes (2 to 10 nm) and very high surface areas (~1000 m 2 /g) with self-assembled monolayers of wellordered functional groups that have high affinity and specificity for specific types of free or complex cations or anions. These sorbents known as SAMMS™ (SelfAssembled Monolayers on Mesoporous Silica) are hybrids of two frontiers in materials science: molecular selfassembly techniques and nanoporous materials. One form of SAMMS™ containing monolayers of mercaptopropyltrismethoxy silane has shown exceptional sorptive properties for mercury and other soft cations such as silver, cadmium, and lead. Another form of SAMMS™ with a functional monolayer consisting of ethylenediamine-Cu(II) complex (Cu-EDA) specifically adsorbs tetrahedral oxyanions such as arsenate, selenate, molybdate, chromate and pertechnetate even in the presence of high concentrations of sulfate. Separation of actinides can be addressed by SAMMS™ material synthesized with a set of monolayer functionalities consisting of hydroxypyridinones, acetamide and propinamide phosphonates. These nanoporous sorbents offer a better choice for efficient and cost-effective removal contaminants from diverse waste streams.","PeriodicalId":6429,"journal":{"name":"2007 Cleantech Conference and Trade Show Cleantech 2007","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2006-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83210630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
