Bimetallic Ag-Zn-BTC/GO composite as highly efficient photocatalyst in the photocatalytic degradation of reactive yellow 145 dye in water

Retracted: Synthesis characterization of Zn-based MOF and their application in degradation of water contaminants

“…As a result, developing techniques to remove it from water, such as photocatalytic degradation, is necessary (Patil & Shukla 2015). Nguyen et al (2021) developed Ag x -Zn 100Àx -BTC/GO nanostructures (BTC: benzene-1,3,5 tricarboxylic, GO: graphene oxide) with varied Ag/Zn molar concentration ratios using hydrothermal-assisted microwave processing. When compared to Zn-BTC/GO and AgBTC/GO, the Ag x -Zn 100Àx -BTC/GO showed exceptional photocatalytic properties in the destruction of RY 145 dye under visible light illumination, with about 100% RY-145 degradation during 0.5 hours.…”

Heterostructure of vanadium pentoxide and mesoporous SBA-15 derived from natural halloysite for highly efficient photocatalytic oxidative desulphurisation

“…9b . Note that the conduction bands of Fe–Al–SBA-15 (0.3 eV) and V 2 O 5 /Fe–Al–SBA-15 (0.25 eV) are more negative than the thermodynamic potential of the H 2 O 2 redox reaction ( E o H 2 O 2 /˙OH = +0.73 eV) 64 and higher than those of the O 2 redox reaction ( E o O 2 /˙O 2 − = −0.33 eV), 65,66 thus the reaction over these catalysts would generate ˙OH radicals rather than ˙O 2 − radicals. The proposed pathway for improving the photocatalytic performance of V 2 O 5 /Fe–Al–SBA-15 is given as follows.…”

Synthesis of a UiO-66/g-C3N4 composite using terephthalic acid obtained from waste plastic for the photocatalytic degradation of the chemical warfare agent simulant, methyl paraoxon

“…5F ) showed that three peaks at 530.69, 531.99, and 533.25 eV were attached to the O in the metal-bound crystal lattice (Zr–O), chemisorbed O species, and O in the O–C O group. 48 The high-resolution spectrum Zr 3d of the UiO-66 sample ( Fig. 5G ) showed signals at 182.88 and 185.19 eV related to Zr 3d 5/2 and Zr 3d 3/2 , respectively.…”

“…5E ) showed that three peaks at 530.81, 532.35, and 533.53 eV were attached to the O in the metal-bonded crystal lattice (Zr–O), the chemisorbed O, and the O in group O–C O. 48 The O 1s spectra of the UiO-66/g-C 3 N 4 -30% sample ( Fig. 5F ) showed that three peaks at 530.69, 531.99, and 533.25 eV were attached to the O in the metal-bound crystal lattice (Zr–O), chemisorbed O species, and O in the O–C O group.…”

“…This increase may be due to the uniform dispersion of the catalyst in a solution, which significantly increased the contact between the DMNP molecules and the active sites of the catalyst. 24,48 When increasing the catalyst dose from 12 mol%, the rate of the DMNP degradation reaction slightly increased. Thus, with a catalytic mass of 2, 4, 6, 8, and 12 mol%, the half-life of DMNP was 11.89, 6.95, 4.67, 2.38, and 2.17 min, respectively.…”
