A review on degradation of organic dyes by using metal oxide semiconductors

Experimental and computational study of metal oxide nanoparticles for the photocatalytic degradation of organic pollutants: a review

“…[21][22][23] According to researchers' investigations, the nanosized particles show an essential photocatalysis process due to their unique chemical and physical properties, high surface-tovolume ratio, fast dissolution, strong sorption, and high reactivity with respect to their bulk of the same compositions. 24,25 Among these nanosized materials, metal oxide nanoparticles (MONPs) are used as prominent photocatalysts. MONPs have a wide range of applications including environmental remediation, energy storage, electrochemistry, sensors, lubrication, coatings, and other various areas of nanotechnology.…”

A post-synthetically modified porous organic polymer for photocatalytic water purification

“…Metal oxide-based photocatalysts like TiO 2 and BiPO 4 have also been studied because of their high photocatalytic activity, chemical stability, and low toxicity. 19,20 However, their application in dye degradation is quite limited by intrinsic properties such as a wide bandgap, fast electron-hole recombination, and excitation under UV light irradiation. Several research efforts have been made to overcome these drawbacks by employing additional catalytic reactants that have also proven to be unsustainable.…”

Advances in Hybrid Composites for Photocatalytic Applications: A Review

“…Photocatalysis has been applied to degrade several types of organic waste, such as dyes [ 3 , 4 ], phenolic compounds [ 5 , 6 ], organohalides, and petroleum hydrocarbons [ 7 ], but also for the removal of heavy metals such as Chromium, Lead, or Mercury among the others [ 8 , 9 ]. The photocatalytic techniques have been applied even to the degradation of pharmaceutical compounds (PC) that represent a new and emerging source of waste in water and soils [ 10 ].…”
