Promotional effect of metal doping on nanostructured TiO2 during the photocatalytic degradation of 4-chlorophenol and naproxen sodium as pollutants

Impact of Doping and Additive Applications on Photocatalyst Textural Properties in Removing Organic Pollutants: A Review

“…The high surface area and the large porous channels of nanorods were among the factors for enhanced performance. Similar results were obtained by Hinojosa-Reyes et al [38] who studied the removal of 4-chlorophenol and naproxen sodium by various dosages of several metal-doped photocatalysts.…”

Recent progress in photocatalytic degradation of chlorinated phenols and reduction of heavy metal ions in water by TiO2-based catalysts

“…Various studies show that the rate of degradation of CPs is dependent on, solution pH [80][81][82][83][84] and molecular structureespecially the number of substituted Cl groups and their positions on the benzene ring relative to the hydroxyl group [85][86][87]. It is well known that the initial degradation rate of most organic pollutants with TiO 2 and other photocatalysts follows the pseudo-first-order reaction model [85,[88][89][90][91]. ), 4-CP (10 ppm) Ni (90%, 80%), Cu (90%, 73%), Fe (37%, 31%) degradation and TOC removal, respectively, in 6 h ), 4-CP concentration (50 mg L −1 ) 100% degradation in 60 min, ∼90% TOC removal in 100 min [101] CdS@TiO , pH = 5) 100%, 76% and 85% degradation in 45…”

Table 2 summarises the recent findings (mainly over the past five years) on the application of TiO 2 -based photocatalysts for the photocatalytic degradation of CPs in aqueous solution.…”

Metal‐Doped Titanium Dioxide for Environmental Remediation, Hydrogen Evolution and Sensing: A Review

“…Photocatalytic activity and kinetic results indicated that the best performance was achieved with 1 wt % Cu doped TiO 2 for the degradation of 4‐CP (degradation performance of 90 %) and for NPX, 1 wt % Fe doped TiO 2 was the photocatalyst (degradation efficiency of 97 %). This photocatalyst‘s exceptional performance was due to the increased concentration of Ti III species and the presence of Cu II and Fe II which worked as heterojunctions of TiO 2 promoting the degradation of organic compounds [56] …”
