Sample preparation solution-state nuclear magnetic

Exploring various phenomena at metal/solution interfaces relates directly to heterogeneous catalysis and its applications to fuel cell catalysis. By the late 1980s, electrochemical nuclear magnetic resonance spectroscopy (EC-NMR) was introduced as a new technique for electrochemical smface science. (See also recent reviews and some representative references covering NMR efforts in gas phase surface science. ) It has been demonstrated that electrochemical nuclear magnetic resonance (EC-NMR) is a local surface and bulk nanoparticle probe that combines solid-state, or frequently metal NMR with electrochemistry. Experiments can be performed either under direct in situ potentiostatic control, or with samples prepared in a separate electrochemical cell, where the potential is both known and constant. Among several virtues, EC-NMR provides an electron-density level description of electrochemical interfaces based on the Eermi level local densities of states (Ef-LDOS). Work to date has been predominantly conducted with C and PtNMR, since these nuclei...
