Abstract

We describe the design, construction, and operation of two types of nuclear magnetic resonance (NMR) sample probes for use in electrocatalysis/surface NMR studies. The first is an electrochemical NMR cell, which permits observation of NMR signals of surface-adsorbed species under external potential control. This cell also permits conventional voltammograms to be recorded from the actual NMR sample. The second or mini-cell has a long, thin sample region and better sensitivity than the electrochemical NMR cell, but is not capable of voltammetry. Spectra have been obtained for 13CO, 13CN- and C15N- adsorbed on polycrystalline platinum black, as a function of applied potential, demonstrating the feasibility of multinuclear NMR studies at electrified interfaces.
