Investigators at Soochow University Detail Findings in Photocatalytics [A Cu(Ii)-tetra(Imidazole) Coordination Polymer and Its G-c3n4 Composite of Photodegradation of Organic Dyes]

2022 DEC 01 (NewsRx) -- By a News Reporter-Staff News Editor at Nanotech Daily -- Current study results on Nanotechnology - Photocatalytics have been published.

Article Description

A Cu(II) coordination polymer {[Cu(tmpe) 0.5 (1,2-bdc)]·2CH 3 CN} n ( Cu(tmpe) ) (tmpe ​= ​1,1,2,2-tetra[4-(2-methyl-1H-imidazole-1-yl)phenyl]ethylene, 1,2-bdc ​= ​1,2-benzenedicarboxylate) was prepared. Cu(tmpe) has the (4,4)-connected 2D structure exhibiting the kgm topology (3 2 ·6 2 ·7 2 ) 2. The series of attached g-C 3 N 4 composites Cu(tmpe)/g-C 3 N 4 were prepared with grinding method and the morphology, functional groups, chemical composition, thermal stability, band gap, optical properties and electrochemical performances of prepared materials were comprehensively characterized with XRD, SEM, HRTEM, EDX, FTIR, XPS, TGA, UV–Vis, PL and electrochemical tests. Cu(tmpe)/10%g-C 3 N 4 had the highest catalytic efficiency for degradation of methylene blue (MB) in a series of Cu(tmpe)/wt%g-C 3 N 4 (w ​= ​5, 10, 15, 20). The photocatalytic study of Cu(tmpe) and its composite Cu(tmpe)/10%g-C 3 N 4 showed high efficiencies of decomposition methylene blue (MB), methyl orange (MO), methyl violet (MV), and rhodamine B (RhB) with the rates were in the order of MB ​> ​MO ​> ​MV ​> ​RhB. Cu(tmpe) and Cu(tmpe)/10%g-C 3 N 4 could degrade 95.4% and 93.6% of MB after 60 ​min and 30 ​min, respectively. The photocatalytic possible mechanism of the degradation process was studied with trapping experiments as well as Mott-Schottky tests. Cu(tmpe) and Cu(tmpe)/10%g-C 3 N 4 composite are good photocatalytic materials for removing organic dye pollutants from wastewater.
