Analysis of Self-Assembled Monolayers on Mesoporous Supports (SAMMS) Materials


EMSL Project ID
25451

Abstract

The ability of self-assembled monolayers on mesoporous silica (SAMMS) to serve as a support for interfacial chemistry has been thoroughly proven by researchers at PNNL and other institutions. We have been adapting this interfacial chemistry for the purpose of conducing tethered catalysis reactions and for making advanced sorbent materials. In all cases, we must thoroughly and accurately characterize the species which we believe we have synthesized on the surface of our support materials. To do this requires access to a number of the advanced surface analytical techniques (TGA, XRD, and NMR) which are available at the EMSL.
