Comparison of the photocatalytic degradation of trypan blue by undoped and silver-doped zinc oxide nanoparticles

Constructing novel Ag nanoparticles anchored on MnO2 nanowires as an efficient visible light driven photocatalyst

“…9 and Fig. 55 In other words, the greater amount of dye molecules competing for the degradation process and the separation of the electron-hole pair was significantly reduced. It was obvious that the photocatalytic activity of Ag@MnO 2 was increased while the amount of Ag loading increased.…”

Comparative study of catalytic activity of ZrO2 nanoparticles for sonocatalytic and photocatalytic degradation of cationic and anionic dyes

“…11 and 12, the efficiency of ZrO 2 NPs was found to decrease with an increase in the initial dye concentration of the VB and DR. This behavior can be explained on the basis that when the initial concentration of dye increases, the Å OH radical ion concentration is reduced correspondingly, so the steady-state concentration of Å OH radicals in US-ZrO 2 NPs causes the degradation efficiency of VB and DR to reduce [38,39].…”

Vitamin B6 Cofactor‐Conjugated Polyethyleneimine‐Passivated Silver Nanoclusters for Fluorescent Sensing of Zn2+ and Cd2+ Using Chemically Modified Cellulose Strips

“…The strip conjugated with PLP_PEI‐AgNCs upon interaction with Zn 2+ and Cd 2+ indicated the elemental bonding occurring between the analyte (Zn 2+ and Cd 2+ ) and PLP_PEI‐AgNCs. Interaction of Zn 2+ with PLP_PEI‐AgNCs shows the presence of two strong peaks with binding energies 1022 eV and 1045 eV due to Zn 2p 3/2 (corresponding to the attachment of hydroxyl groups to zinc ions on the surface) and Zn 2p 1/2 (corresponding to Zn atoms bonding to oxygen atoms and not Zn‐C−O alloys) in the XPS spectra (Figure 6 f ) . As shown in Figure 6 g , the deconvolution of the Cd 3d 5/2 peak renders peaks with binding energies at 404.5 eV and 405.4 eV.…”
