Facile synthesis of silver and polyacrylic acid doped magnesium oxide nanostructure for photocatalytic dye degradation and bactericidal behavior

Bactericidal Action and Industrial Dye Degradation of Graphene Oxide and Polyacrylic Acid-Doped SnO2Quantum Dots:In SilicoMolecular Docking Study

“…Various methods for degrading dyes have been adopted for synthesizing metal oxides, including hydrothermal, co-precipitation, sol−gel, and so forth. 26 From these methods, the co-precipitation technique is used as it is eco-friendly, inexpensive, energy-efficient, and easy to use with a short preparation time. 27 However, SnO 2 has the limitation of a high recombination rate.…”

Comparative Study of Sonophotocatalytic, Photocatalytic, and Catalytic Activities of Magnesium and Chitosan-Doped Tin Oxide Quantum Dots

“…In an acidic dye solution, adsorption of cationic species is limited and attributed to a positively charged catalyst surface. The adsorption of MB dye enhanced in basic medium, manifesting the large electrostatic interaction between the MB dye and negatively charged catalyst that causes the surface charges to become negative . Moreover, the addition of CS enhanced the photocatalytic degradation of MB, attributed to the occurrence of amino and hydroxyl groups in CS .…”

“…Both the crystallite size and Eg decreased with CS and Mg doping due to the substitution of Mg 2+ ions into SnO 2 QDs and matched well with those in the literature. 37 − 39 The reduction of Eg might be associated with the existence of holes in Mg-doped QDs. Due to the lower valence compared to that of Sn 4+ , all substitutional Mg atoms will produce two holes in the O 2p state that may create an impurity band in the Eg region.…”

“…The adsorption of MB dye enhanced in basic medium, manifesting the large electrostatic interaction between the MB dye and negatively charged catalyst that causes the surface charges to become negative. 39 Moreover, the addition of CS enhanced the photocatalytic degradation of MB, attributed to the occurrence of amino and hydroxyl groups in CS. 38 The incorporation of Mg also enhanced the PCA, which served as an electron acceptor and separated the e – –h + pair; consequently, the trapped electron shifted to absorb the oxygen molecule.…”

Effect of the green synthesis of CuO plate-like nanoparticles on their photodegradation and antibacterial activities

“…11,12 Apart from engineering and technological applications, nanoparticles can be used to upgrade the environment by remediating environmental contaminants. [13][14][15] Nowadays, air, water, soil, and sound pollution are predominant problems around the globe. [16][17][18] The principal sources of such pollution in many cases is from industrial wastes and effluents.…”
