The study presents a breakthrough of a balanced charge separation for heterojunction CuWO4-TiO2 cocatalyst to efficiently enhance visible light photocatalytic degradation of ciprofloxacin (CIP). A solvothermal-synthesized nanopyramid-like CuWO4 semiconductor was assembled before sol–gel treatment with TiO2 precursors to generate CuWO4-TiO2 nanocomp...

... 2 anatase characteristic peaks were confirmed at to a flattened FTIR spectra in this region leaving a significant appearance of Ti-OH and W-OH existing around broad peak region of 2066 cm −1 . Figure 2b shows XRD phase properties for TiO 2 , CuWO 4 , and xCuWO 4 -TiO 2 (CWT) indexed to 8.8 nm tetragonal planar anatase (JCPDS No. 00-064-0863) (Nagakawa and Nagata 2021), 9.1 nm triclinic phase (ICSD no ...

... spectra displayed in Fig. 2c-d represent the phase purity of TiO 2 , CuWO 4 , and CuWO 4 -TiO 2 . TiO 2 samples in Fig. 3c showed the Raman modes: E g1 (at 146.9 cm −1 ) , B 1g (at 399.99 cm −1 ), A 1g (at 519 cm −1 ) and E g (at 640.12 cm −1 ). These TiO 2 bands were previously identified at lower wavenumbers of 141, 390, 512, and 634 cm −1 ( Luo et al. 2016). The ...
