Remediation of water containing phosphate using ceria nanoparticles decorated partially reduced graphene oxide (CeO2-PRGO) composite

Gold-selenide quantum dots supported onto cesium ferrite nanocomposites for the efficient degradation of rhodamine B

“…Nitrogen adsorption desorption isotherms of the as-synthesized Cs 2 Fe 2 O 4 NC and x wt.% AuSe QDs/Cs 2 Fe 2 O 4 NC samples were displayed in Figure 6 , which exhibited type-IV isotherms according to IUPAC classification [ 57 , 58 , 59 ] and have inflection around P/P o (0.20–0.40) with narrow hysteresis loops. The specific surface area of the Cs 2 Fe 2 O 4 NC and x wt.% AuSe QDs/Cs 2 Fe 2 O 4 NCs was calculated from the isotherms.…”

Enhanced performance of hydroxyl and cyano group functionalized graphitic carbon nitride for efficient removal of crystal violet and methylene blue from wastewater

“…6B and S3(B), † respectively. 3,49,50 Using the Langmuir model, the correlation coefficient (R 2 ) was 0.999 (Table 1), which was much greater than that (R 2 = 0.885) obtained using the Freundlich model. Furthermore, the adsorption capacity values of the Langmuir model were consistent with the experimental results described in Table 1.…”

Photocatalytic Degradation of Methylene Blue under Visible Light Using TiO2 Thin Films Impregnated with Porphyrin and Anderson-Type Polyoxometalates (Cu and Zn)

“…It consists of the irradiation of a catalyst surface with enough energy to generate photoexcitation, producing highly oxidizing species that allow the degradation or mineralization of pollutants on a liquid or gaseous phase [3]. In photocatalysis, semiconductors (e.g., SnO 2 , ZnO or TiO 2 [4]) and hybrid materials (quantum dots, composites [5][6][7]) are usually used as the active phase. The TiO 2 surface chemical properties rely on the electronic properties of the semiconductor surface, and it is one of the reasons for its high interest in photocatalytic applications [8].…”
