Description
Summary:Visible-light-driven photocatalytic CO 2 reduction can address climate change and energy short-age. Homogenous photocatalysis converted CO 2 to value chemicals have a straightforward procedure synthesis and CO 2 conversion mechanism. Rhenium complexes based on pyridyl-triazole work as efficient catalysts for CO 2 reduction at room conditions and under visible light. Photo-catalytic measurements show Re(bpy-COOH) possesses the highest catalytic CO 2 conversion activity, whereas Re(Hpytr) is the lowest catalytic activity. These complexes posses the high product selectively, which produce two gases CO and H2 with high CO selectively. CO selectivity of Re(bpy-COOH), Re(Hphtr), and Re(Hpytr) are determined by 99.0, 97.9 and 92.8, respectively. TONCO reaches the highest value at 100 min are 5.46, 1.56, and 0.51 for Re(bpy-COOH), Re(Hphtr), and Re(Hpytr), respectively. This study explore the new property as photocatalysts active for CO 2 reduction of these complexes with high CO selectively.
