Synthesis and Characterization of Hetero-metallic Oxides-Reduced Graphene Oxide Nanocomposites for Photocatalytic Applications

AgO@InGaZnO4 composites for environmental photocatalysis

“…[13] Other papers showed experimentally measured bandgaps of AgO between 1.6 and 2.2 eV. [14][15][16] However, we found that AgO in these papers was prepared by the solid phase method and precipitation method, which may be somewhat different from the samples prepared by photodeposition. In this paper, AgO is also treated as a metal and is considered to act as an electron sink like a metal cocatalyst.…”

“…The degradation of dyes in the same field is more studied, for example, the kinetic constant of AgO photocatalyst for the degradation of methylene blue is 0.0250 min À 1 . [16] Others such as Bi 2 WO 6 , [24] Bi 2 InTaO 7 -3 %Cu, [34] Bi 2 GaTaO 7 -2 %Cu, [34] Bi 2 Ga 3.2 Fe 0.8 O 9 -2.5 %Cu, [35] and Bi 2 Ga 2.8 Al 1.2 O 9 -2.5 %Cu [36] in the reaction of photodegradation of RhB have kinetic constants in…”

“…[12] Ag-ETS-10 sample was used to decompose methyl blue. [13] Besides the most commonly used metallic Ag, AgO has also been used to form composites with other semiconductor materials in photocatalytic studies, such as AgO-loaded TiO 2 and BiVO 4 , [14] Fe 3 O 4 @SiO 2 @AgO, [15] AgO.CuO.WO 3 /rGO, [16] AgO-CoO-CdO/ PASCSGO, [17] and AgO/Ag 2 O@TiO 2 . [18] In photocatalysis, all the above mentioned AgO-containing composites were used for the removal of organic matter and dyes.…”

Novel MgFe2O4-CuO/GO heterojunction magnetic nanocomposite: Synthesis, characterization, and batch photocatalytic degradation of methylene blue dye

“…It is well reported that • O2 − and • OH radicals are the reactive species responsible for the initiating photooxidative degradation reaction of MB in the catalytic system [1,25,75]. Based on that, a possible mechanism (Fig.…”

“…Organic dye industry effluents like methylene blue dye (MB) which has a non-biodegradable aromatic structure and absorbs the majority of sunlight radiation, accumulates in wastewater and causes serious damage to marine ecosystems and human life [1][2][3][4][5]. As a result, the elimination of such dyes from wastewater has become a priority for many researchers worldwide [6][7][8][9][10].…”
