Designing inorganic–magnetic–organic nanohybrids for producing effective photocatalysts for the purification of water

Abstract

The present study describes a new strategy for modifying the structure of zinc oxide for removing colored pollutants from water after a few minutes of light irradiation.

Engineering the Integration of Titanium and Nickel into Zinc Oxide Nanocomposites through Nanolayered Structures and Nanohybrids to Design Effective Photocatalysts for Purifying Water from Industrial Pollutants

“…Photocatalytic processes are a kind of benign light-based technique whereby light is used as an energy source to excite photoactive materials and produce strong oxidizing agents that convert the organic pollutants to CO 2 and water. Previous studies of photocatalytic processes [1][2][3] concluded that the structure of the photocatalysts plays an important role in increasing their photo-related activities and the efficiency of the photocatalytic processes. Saber et al [1,2] designed novel nanohybrids based on inorganicmagnetic-organic structures for increasing the performance of photocatalysts to remove dyes from water.…”

In addition, Ljubas et al [3] utilized nanostructured titanium oxide on a glass with a simulated solar radiation lamp for the complete removal of pharmaceutical compounds from water through photocatalytic processes.…”

Nanolayered Structures and Nanohybrids Based on a Ternary System Co/Ti/Zn for Production of Photo-Active Nanocomposites and Purification of Water Using Light

“…Photocatalytic degradation is one of the most familiar processes belonging to these techniques. Many researchers used photocatalytic reactions for removing pollutants [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. In these studies, the researchers tried to prepare and design effective optical materials because the performance of the photocatalytic processes depends mainly on the structure of the optical materials.…”

“…Among the different kinds of materials, nanolayered structures based on layered double hydroxides (LDHs) have many advantages for preparing optical active materials. LDHs consist of several nanolayers connecting through pillars with a large interlayered space [ 3 , 4 , 5 ]. These nanolayers have a cationic nature because they contain different metals with different valences such as di-, tri-, and tetra-valent metals.…”

“…Depending on the nature and the size of the anionic pillars, the internal spacing among the nanolayers can be controlled and changed to appear as a large spectrum of known or unknown properties. By using organic pillars, different kinds of organic–inorganic nanohybrids can be formed to produce an almost unlimited set of new compounds [ 3 , 4 , 5 ].…”
