抄録	We studied the quantized conductance behavior of mechanically fabricated Pt nanoconstrictions under electrochemical potential control in H2SO4, Na2SO4, and NaOH solutions. There was no clear feature in the conductance histogram, when the electrochemical potential of the nanoconstrictions was kept at the double layer or the under potential deposited hydrogen potential. At the hydrogen evolution potential, the conductance histograms showed clear features around 0.5 and 1 G0 in the H2SO4 solution. In Na2SO4, and NaOH solutions, a 1 G0 feature with a shoulder appeared in the histogram. The quantized conductance behavior of Pt nanoconstrictions could be controlled by the electrochemical potential and solution pH.
