Oriented 0001 CdX X S, Se crystals selectively adsorb MoS42 onto the Cadmium rich faces. Binding of MoS42 is effected by dipping the CdX crystals into CH3CN containing 20 mM Et4N2MoS4. Removal of the crystal from the solution followed by rinsing with CH3CN leaves MoS42 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 51 as determined by XPS and AES data for both faces of the same crystal. Keywords Cadmium rich crystals, Electrochemistry.
