Face-Specific Interaction of MoS4(2-) with Oriented Crystals of (0001) Cdx (X = Se, S)

Abstract

Oriented (0001) CdX (X = S, Se) crystals selectively adsorb MoS4(2) onto the Cadmium rich faces. Binding of MoS4(2) is effected by dipping the CdX crystals into CH3CN containing 20 mM (Et4N)2MoS4. Removal of the crystal from the solution followed by rinsing with CH3CN leaves MoS4(2) on the Cd but not X- rich face of the crystal as detected by X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES). The specificity for Cd-face vs. X-face binding is typically greater than 5:1 as determined by XPS and AES data for both faces of the same crystal. Keywords: Cadmium rich crystals, Electrochemistry.
