Eco-friendly synthesis of self-regenerative low-cost biosorbent by the incorporation of CuO: a photocatalyst sensitive to visible light irradiation for azo dye removal

Enhancing solar absorbance using a 2D graphene oxide/CuO composite film for efficient solar desalination

“…The two strong peaks located at 35.5° and 38.7° correspond to the (11-1) and (111) crystal planes of CuO, respectively. 30 In the XRD patterns of all the GO/CuO films, the typical diffraction peaks indexed to GO were observed at 10.7° and 26.0°, corresponding to the (001) and (002) crystal planes of GO, respectively. 31 Upon increasing the concentration of CuO, the intensity of the peak related to CuO also increased.…”

Hierarchical structured Cu@carbon/carbon cloth film with high levels of light absorption for efficient solar thermal desalination

“…The CC has a wide diffraction peak around 26.5°without displaying other peaks, indicating a high purity of CC. 27,28 Once the Cu NPs coupled with CC, all Cu and CC peaks can be seen in the XRD patterns of Cu@C/CC. As the content of Cu increases, the intensity of the characteristic peak corresponding to Cu increases as well.…”

Activated Sludge-Assisted Phytoremediation For Dye Removal

“…The Lemna biomass was also observed after phytoremediation experiments using the CBS (centered backscattered electrons) mode which is sensitive to the differential phase mode. From Figure 9c, e we can observe that the two dyes are present on the surface of the white colored biomass suggesting that the plant biomass can accumulate organic dyes on the frond surface, revealing the signi cant a nity of duckweed for anionic dyes (Khaled et al 2020). To support the above observation, the EDX results summarized in Table 7 showed that there was a major change in the composition of the biomass where the mass percentage of C, N and O increased after phytoremediation experiments con rming that most of the dyes present in the solution have been eliminated by phytoaccumulation process (Hocini et al 2020).…”
