Electrochemical step edge decoration

In the first step, amorphous MoO , nanowires were electrodeposited by ESED according to the reaction 

In the second step, these MoOj NWs were converted to M0S2 by exposure to H2S within either of two temperature regimes (500-700 °C or 800-1,000 °C) according to the reaction (for x = 2) 

According to absorption spectroscopy, these nanoribbons were composed of 3R-M0S2. The E/C synthesis of M0S2 wires and ribbons was size selective control over the wire or ribbon size was provided by control of the MoO , nanowire dimensions, which in turn were controlled using the electrodeposition potential and time in the first step of the synthesis.
