Employing Cu(II) complexes of N,O-donor ligand for catalysis in visible light driven cleavage of lignin C-C bonds

Mechanistic Investigation of Oxidative Methanol Carbonylation with Mixed Cu(I)/Cu(II)–N-Methylimidazole Catalysts

“…FT-IR analysis was further carried out to verify the chemical structure of the prepared copper complex catalysts. As shown in Figure a, the peaks at 1240, 1525, and 3125 cm –1 indicate the presence of C–N, CN, and C–H bonds in the NMI ligand. , The peaks at 1109, 2825 and 2938, and 3318 cm –1 are ascribed to stretching vibrations of C–O, C–H, and alcohol-OH, respectively . The enlarged FT-IR spectra of copper complex catalysts between 930 and 970 cm –1 are presented, and the peaks at 950 cm –1 may be attributed to ν­(Cu–N), suggesting that the NMI ligand coordinated with copper ions to form metal–organic complexes. , The UV–vis absorption spectroscopic investigation was also conducted to further confirm the coordination structure of the copper complex catalysts.…”

Six polyoxotungstate-based transition metal compounds for electrochemical capacitor application and a comparative analysis of factors affecting capacitances

“…Consequently, scientists have been motivated to explore alternative candidates. Meanwhile, transition metal complexes, known for their high specific surface area, adjustable pore size and good thermal stability, have found extensive application prospects in magnetism, [29][30][31][32][33] catalysis, [34][35][36] luminescence, 34,37,38 electrochemical sensors, [39][40][41] etc. As a result, an encouraging strategy of incorporating POMs into transition metal complexes (TMCs) to build POM-based transition metal complexes (POM-TMCs) was put forward.…”
