Synthesis, Structural Characterization, Hirschfeld Surface Analysis and Photocatalytic CO2 Reduction of Yb(III) Complex with 4-Aacetylphenoxyacetic Acid and 1,10-Phenanthroline Ligands

Abstract

A new nine-coordinated Yb(III) complex [YbL3(Phen)] (1) (HL = 2-(4-acetylphenoxy)acetic acid (APA), Phen = 1,10-phenanthroline) was synthesized with 2-(4-acetylphenoxy)acetic acid, YbCl3.6H2O, NaOH and 1,10-phenanthroline as materials. Complex (1) was characterized by IR and X-ray single-crystal diffraction analysis. The results show that the Yb(III) ion is nine-coordinated with seven carboxylate oxygen atoms from five different deprotonated APA ligands and two nitrogen atoms from one Phen ligand. Complex (1) forms a 3D supramolecular framework through the - stacking interactions between the Phen aromatic rings. The hirschfeld surface analysis of complex (1) was also calculated. The CO2 photoconversion activity of complex (1) has been performed under UV-vis light irradiation. The complex (1) shows good photocatalytic activity with the yield of CO is closed to 146 mmol/g after three hours of UV-vis light irradiation, the CO selectivity has reached to 97.9%.

“…However, the shortcomings of expensive costs and difficult synthesis limit the further applications of the above material catalysts. Recently, metal complexes such as cobalt complexes [ 14 , 15 ], Mn tricarbonyl bipyridyl complexes [ 16 ], Cu(I) complexes [ 17 ], Fe(II)-1,10-phenanthroline complexes [ 18 ], Ru(II) binuclear complexes [ 19 ], and rare earth metal complexes [ 20 , 21 ] have become a research hotspot in photocatalytic CO 2 reduction because of their simple synthesis and low price. However, the above studies of complex materials have focused on transition metal and rare earth complexes.…”

Synthesis, Structural Characterization, and Hirschfeld Surface Analysis of a New Cu(II) Complex and Its Role in Photocatalytic CO2 Reduction

“…However, due to the high cost of these noble metal complexes, the use of earth-abundant metal complexes as catalysts for photocatalytic CO 2 reduction has attracted increasing attention from chemists and material scientists. Among these complexes, Co(II), Mn(II), Fe(II), Cu(I), and rare earth ions containing complexes have been used for photocatalytic CO 2 reduction [16][17][18][19][20][21][22][23][24]. However, to date, there are very few reports on the photocatalytic CO 2 reduction by Cu(II) complexes [25][26][27].…”

The Synthesis, Structural Characterization, and DFT Calculation of a New Binuclear Gd(III) Complex with 4-Aacetylphenoxyacetic Acid and 1,10-Phenanthroline Ligands and Its Roles in Catalytic Activity

“…Over the past ten years, metal complexes have garnered considerable attention as catalysts in photocatalytic CO2 reduction and benzyl alcohol oxidation reactions due to their tunable properties, simple synthesis, and catalytic activity. Some metal complexes, such as the Co(II) complex [16,17], Mn(II) complex [18], Cu(I) complexes [19], Fe(II) complex [20], Ru(II) complex [21], and Ln(III) complexes [22,23], have shown excellent catalytic activity and selectivity in photocatalytic CO2 reduction. For example, the Co(II) complex catalyst shows high photocatalytic CO2 reduction activity with a catalytic rate of 3012.5 μmol•g −1 •h −1 [17].…”
