Future applications of porous materials require novel ones with designed morphology (e.g., pore shape and volume) and predetermined surface properties. The pore distribution and nature of interaction between the porous host and its guest sorbate is directly correlated to the ability to achieve a desired function in a particular application. Hence, a bottom-up synthetic approach at the nano-scale via templated and functionalization mechanisms is needed to tailor the final materials properties. 

anoporous Materials for Gas Separation and Multifunctional Catalysis The IRG3 aims at addressing specific overall challenges pertaining to the preparation and application of nanoporous materials. Objectives and applications relate mostly to the 2nd and 4th Nanotechnology generations suggested by Roco [1]: (i) controlling the size, shape and volume of pores during and after synthesis; (ii) achieving selectivity in separations of similar-sized molecules; (iii) preparation of materials with tunable surface properties; and (iv) preparation and use of nanoporous multifunctional catalysts. The specific applications to be studied are: (i) selective natural gas purification via adsorption at ambient temperature; (ii) gas storage with redox-active metal-organic frameworks; and (iii); and catalytic conversion of biomass resources into renewable fuels. The IRG3 members made seminal contributions in areas such as synthesis and characterization of nanoporous materials, separations via adsorption, and catalysis. The proposed objectives are a natural outgrowth of externally funded programs: NSF PREM (Hernández), NASA-URC Center for Nanoscale Materials (Raptis), and Hernández’s NSF-CAREER grant. The necessary infrastructure (besides the solicited equipment) is already in place and includes X-ray diffraction facilities (NSF-MRI to Hernández) and instrumentation provided by the NSF-EPSCoR IFN (Cardona, Hernández, Raptis).
