Abstract

[Co(bds)<sub>2</sub>][<italic>n</italic>Bu<sub>4</sub>N] (where bds = 1,2-benzenediselenolate) was identified as an electrocatalyst for H<sub>2</sub> evolution. Mechanistic studies indicate that with acid a protonated oligomeric {[Co(bds)<sub>2</sub>(H)<sub>x</sub>]<sup>x−1</sup>}<sub>m</sub> is formed, which was found to reenter the catalytic cycle and generate H<sub>2</sub>.
