Design Changes That Lead to Large Effects in Photocatalysis: A Ruthenium–Terpyridine Complex Stable and Active Enough to Outperform [Ru(bpy)<sub>3</sub>]<sup>2+</sup>
Listed in ZivaHub and Deakin Research Online and DMU Figshare — shown once because both records carry DOI 10.1021/acs.inorgchem.6c02048.s001
We report here the synthesis of a new heteroleptic ruthenium–terpyridine complex that exhibits both high stability and enhanced photocatalytic activity with an increase of approximately one order of magnitude for the hydrogen evolution reaction coming from a strong push–pull effect.
Description
The complex demonstrates high performance under blue light (445 nm), achieving a turnover number (TON) above 3500 mol<sub>H<sub>2</sub></sub> mol<sub>PS<sup>–1</sup></sub> with sustained hydrogen production for over 6 days.
That TON value is more than twice as high as that of the reference [Ru(bpy)<sub>3</sub>]<sup>2+</sup> complex under the same conditions. Under red light (630 nm), this complex also shows high efficiency and stability with no significant decrease in the turnover frequency over 6 days, achieving a TON over 960 mol<sub>H<sub>2</sub></sub> mol<sub>PS<sup>-1</sup></sub>, a value competitive with reference [Ru(bpy)<sub>3</sub>]<sup>2+</sup> complex under blue light (this last showing no hydrogen evolution under red-light).

We identified a kinetic competition between the main H<sub>2</sub> production process and degradation reactions from the reduced complex species and could further enhance the sustainability of the system (under blue light) by increasing the cobalt catalyst concentration. A TON above 4100 mol<sub>H<sub>2</sub></sub> mol<sub>PS<sup>-1</sup></sub> could be reached after 8 days.
