Employing graphite-conjugated catalysts in CO2 reduction demonstrates a possible application in energy conversion reactions with increased stability of the electrocatalyst. fac-Re(5,6-diamino-1,10-phenanthroline)(CO)3Cl covalently conjugated to graphite resulted in a graphite-conjugated rhenium material that was highly active in the CO2 to CO reduction in acetonitrile (Figure ). The graphiteconjugated Re catalyst displayed 96 ± 3 % Faradaic efficiency and turnover numbers greater than 12,000. The cyclic voltammogram of the graphite-conjugated rhenium material, recorded under catalytic conditions (CO2-saturated acetonitrile with 0.1 M tetrabutylammonium hexafluorophosphate electrolyte), displayed a catalytic current at 10 mA cm -2 at -2.09 V with CO as the only product. Covalent conjugation of rhenium onto the glassy carbon electrode increased the stability of the compound compared to adsorption or electropolymerization methods. The graphite-conjugated Re catalyst remained robust for 1.4 ± 0.3 h with a sustained catalytic activity at 1.0 mA. An enhanced activity compared to the homogenous analogue, high selectivity for CO, and extended durability of the catalyst were observed.
