Abstract

<abstract abstract-type="main"> <title>SUMMARY</title> <p>A noble‐metal‐free molecular catalyst, [Co(dmbp)₃]Cl₂ (dmbp = 4, 4^'‐dimethyl‐2, 2^'‐bipyridyl) was prepared for photocatalytic H₂ generation. A three‐component photocatalytic system was constructed by combination of [Co(dmbp)₃]Cl₂ as catalyst, Eosin Y as photosensitizer and triethylamine as sacrificial electron donor to give an efficient H₂ generation system under visible‐light irradiation (λ &gt; 420 nm). The maximum H₂ yield was up to 249.2 turnover number (vs. catalyst) over 2 h irradiation under the conditions with catalyst of 4.0 × 10⁻⁴ M, 10% TEA (v/v), EY²⁻ of 4.0 <bold>×</bold> 10⁻⁴ M and pH 10 in MeCN/H₂O (1 : 1, v/v). Furthermore, the dynamics behaviors of the photolysis system were also briefly discussed. Copyright © 2014 John Wiley &amp; Sons, Ltd.</p> </abstract>
