Rittmann will formulate a mechanistic and predictive model of photobiocatalysis by incorporating the parameters determined in the molecular, ecological, and engineering studies to evaluate chemical and biochemical reactions and microbial community responses. Gray will evaluate the effectiveness of novel reactor designs for the integration of photocatalysis as a post-treatment strategy in biotreatment. The research goal of this group is to generate knowledge to develop synthesis strategies for superior catalysts and to understand the chemistry of this interesting and technologically important reaction. Synthesis and structural characterization Dr. Sachtler will synthesize, characterize, and evaluate zeolite-based catalysts. Since this complex requires two Al-centered tetrahedra within a distance of 0.
Fe complexes is understandable.
The results, coupled with appropriate characterization of the iron species to be formed in the zeohte, will be very informative for understanding the nature of the active sites. Sachtler found that small amounts of added La 2 O 3 increase the selectivity. Other zeolites, e.g. ferrierite and beta, could be used as support instead of ZSM-5 to test the role of the channel structure. 2 O and O 2 . As no one-phase material is expected to catalyze all these processes in an optimum Drnner, they will try to design combinations of solids, each exposing sites of high activity for one or two of these processes.
