Cobalt-terpyridine compounds have been shown to be catalysts for CO<sub>2<\/sub> reduction to CO while simultaneously producing H<sub>2<\/sub> from the requisite proton source. To investigate the parameters governing the competition for H<sup>+<\/sup> reduction <i>versus<\/i> CO<sub>2<\/sub> reduction, the cobalt bisterpyridine class of compounds is first evaluated as H<sup>+<\/sup> reduction catalysts. We report that electronic tuning of the ancillary ligand sphere can result in a wide range of second-order rate constants for H<sup>+<\/sup> reduction. When this class of compounds is next submitted to CO<sub>2<\/sub> reduction conditions, a trend is found in which the less active catalysts for H<sup>+<\/sup> reduction are the more selective towards CO<sub>2<\/sub> reduction to CO. This represents the first report of the selectivity of a molecular system for CO<sub>2<\/sub> reduction being controlled through turning off one of the competing reactions. The activities of the series of catalysts are evaluated through <i>foot-of-the-wave<\/i> analysis and a catalytic Tafel plot is provided.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1039\/c4sc03766a Authors: No\u00e9mie Elgrishi, Matthew B.
