Design Strategy toward Recyclable and Highly Efficient Heterogeneous Catalysts for the Hydrogenation of CO<sub>2</sub> to Formate
One bottleneck in
the realization of CO<sub>2</sub> conversion
into value-added compounds is the lack of catalysts with both excellent
activity and recyclability. Herein, a catalyst is designed for the
hydrogenation of CO<sub>2</sub> to formate to boost up these features
by considering the leaching pathway of previously reported heterogenized
catalyst; the design strategy incorporates oxyanionic ligand(s) in
the coordination sphere to provide a pathway for both preventing the
deleterious interactions and assisting the heterolysis of H<sub>2</sub>. The tailored heterogenized catalyst, [bpy-CTF-RuÂ(acac)<sub>2</sub>]ÂCl, demonstrated excellent recyclability over consecutive runs with
a highest turnover frequency of 22 700 h<sup>–1</sup>, and produced a highest formate concentration of 1.8 M in 3 h. This
work is significant in elucidating new principles for the development
of industrially viable hydrogenation catalysts
