Inverted and amplified waves in cyclic voltammograms of [PtH(PEt3)3]+; catalytic production of hydrogen at a mercury electrode
Abstract
Cyclic voltammograms of solutions of [PtH(PEt3)3]+ in phosphate buffer (pH 6.88) at mercury electrodes show large reduction waves on all forward and reverse scans except the first negative scan, which are interpreted in terms of catalytical hydrogen production; sustained hydrogen production occurs at –1.7 V vs. standard calomel electrode after initiation.
