Synthesis of visible light driven ZnO: Characterization and photocatalytic performance

Green synthesis of zinc oxide nano-sized spherical particles using Terminalia chebula fruits extract for their photocatalytic applications

“…The underlying mechanism of the photocatalytic degradation of RhB by the ZnO-NPs under irradiation can be explained on the basis of photogeneration of electronhole pairs (excitons) in ZnO-NP. molecules have the strong oxidative potential for partial or complete decomposition of various organic, inorganic and microbial contaminants adsorbed on the photocatalyst surface [37][38][39][40].…”

Microwave accelerated synthesis of zinc oxide nanoplates and their enhanced photocatalytic activity under UV and solar illuminations

“…So far, various physical and chemical methods like chemical precipitation, thermal decomposition, high energy ball milling, hydrothermal synthesis, spray pyrolysis, sonochemical synthesis, vapour deposition and evaporation methods were employed for preparing the size and shape selective zinc oxide nano materials [9][10][11][12]. Eventhough many attempts have been made for the bulk level preparation of this novel material, a simple, greener and cost effective approach is still in demand.…”

“…It shows exceptional features like high electron mobility, high transparency, biocompatibility, excellent chemical and thermal stability [7,8]. On the basis of these reasons, zinc based oxide nanostructures are acknowledged as the best photocatalysts for any practical applications [9,10].…”

“…Where as, the sun light stimulated activity can be due to the defect related transitions (Fig.S4). When compared with other open morphologies, the ZnO nanoplate structures have more open surfaces to interact with light[9,16]. As the redox reactions proceeds along the surface of ZnO, the oxygen defects present in the nanoparticle surface functions as the active sites for the better catalytic activity.…”

A novel reusable nanocomposite: FeOOH/CBC and its adsorptive property for methyl orange

“…Many techniques have been used so far [1]. Chemical oxidation [2,3], membrane filtration [4], magnetic separation [5], coagulation [6,7], biodegradation [8], photocatalysis degradation [9][10][11] and adsorption [12,13] are most widely used for removing dyes from effluents. Among the numerous techniques of dye removal, adsorption is one of the most attractive methods due to its high effectiveness, economy, operational simplicity and low energy consumption [14][15][16][17].…”
