Designed synthesis of hematite-based nanosorbents for dye removal

Influence of chemical structure of dyes on capacitive dye removal from solutions

“…The development of methods of dye removal from solutions is a subject of intense experimental works. Many investigations were focused on the development of efficient adsorbents [31][32][33]. Efforts to increase dye removal efficiency have resulted in the development of adsorbent materials with magnetic properties [34].…”

Photocatalytic upgrading α-Fe2O3 nanoparticles by incorporating MoS2/rGO nanosheets

“…Effective use of electron-hole pairs is a key factor in rapid degradation of organic pollutants but the determinant step in the process is recombination of electrons and holes causing the weakening of the photocatalytic activity of many common semiconducting metal oxides [2][3][4]. Thus, in recent years, various approaches have been proposed to strengthen the photocatalytic activity of semiconductors, including the increase of external surface area, surface/morphology modification or creating structural defects [1,2,[6][7][8]. Among them, modifying the surface of metal oxide semiconductors using noble metals such as platinum and palladium is one of the most successful methods to boost the photocatalytic activity.…”

Highly monodispersed hematite cubes for removal of ionic dyes

“…Various chemical and physical treatment techniques and processes have been used to remove the dye pollutants from contaminated water. The adsorption [2][3][4] and catalytic oxidation processes, especially heterogeneous photocatalysis [5,6], are the most successful methods for removal of dye pollutants from water. The development of new materials with higher pollutant removal capacity and reuse ability has contributed significantly to the treatment of contaminated effluents.…”
