Uncapped SnO2 quantum dots for selective adsorption, separation and photocatalytic degradation of a mixture of dyes

“…23 The zinc oxide (ZnO) flakes@Zeolite core-shell was shown to have an adsorption capacity of 74.661 mg g À1 in 60 min. 24 Similarly, Bi 2 O 3 -SrO-FeO@SiO 2 nanocomposites and a microwave irradiation method were reported to show an adsorption capacity of 294.11 mg g À1 for the MB dye. 25 Nanostructured TiO 2 , tin oxide (SnO 2 ), ZnO, V 2 O 5 , iron(III) oxide (Fe 2 O 3 ), and their derivatives were also utilized for photocatalytic dye degradation as well as for adsorption.…”

Preparation and Upscaling of Zeolite@TiO2 Core‐shell for the Removal of Pb(II) and Methylene Blue Dye from Wastewater

“…[28][29][30] Recently, zeolite core-shell particles with porous shell of ZnO Nano flakes have been reported which imparts photocatalytic, antibacterial properties and rapid adsorption of Pb(II) and methylene blue due to negatively charged surface. [31][32] In the present work, a core-shell composite adsorbent material has been designed by growing nano TiO 2 particles in multi layers over the surface of zeolite. [33] A surfactant-assisted process helps in the uniform growth of the TiO 2 nanoparticles on zeolite without negatively affecting its functionality.…”

“…These advanced zeolite materials are being prepared by different modifications of surface by functionalized nanoparticles for simultaneous and facile removal of heavy metals, organic pollutants and microorganisms from contaminated water [28–30] . Recently, zeolite core‐shell particles with porous shell of ZnO Nano flakes have been reported which imparts photocatalytic, antibacterial properties and rapid adsorption of Pb(II) and methylene blue due to negatively charged surface [31–32] …”

Creating Synergy of Microporous Hydrophilic–Organophilic Surfaces in Zeolite@Nano‐Titania Particles for Rapid Removal of Diverse Pollutants in Water

“…The present work relates to the design and synthesis of zeolite@nano‐titania core–shell particles in which zeolite CBV 500 (organophilic) [ 9 ] is coated with multiple layers of nano‐titania (hydrophilic) [ 10 ] to create a multifunctional system wherein hydrophilicity, diffusivity, photocatalytic activity, and antibacterial characteristics are introduced by nano‐titania shell while cation exchange property and organophilicity is retained by zeolite core. Selection of appropriate zeolite with high silica to alumina ratio (5:2) introduces organophilic effect in zeolite owing to the presence of neutral silica surface and absence of projecting silanols.…”
