Novel iron metal matrix composite reinforced by quartz sand for the effective dechlorination of aqueous 2-chlorophenol

Degradation of 4‐chlorophenol by BM Fe/Cu‐O2 system: The symbiosis of and ·OH radicals

“…The preparation method of BM Fe/Cu bimetallic powder was reported in previous studies (Zhang, Yang, Han, et al., ). Typically, BM was performed in a planetary ball mill (QM‐3SP04, Nanjing University Instrument Corporation) at a rotation speed of 550 rpm.…”

“…The removal efficiency of perfluorocarbon was more than 97%. Recently, a water treatment agent prepared by BM method was frequently applied in photocatalysts (Fu, Hu, Yang, Liu, & Chen, 2013;Shifu et al, 2009), dechlorination agents (Xu et al, 2012;Zhang, Yang, Han, et al, 2016), adsorbents (Simeonidis et al, 2011;Zhang, Moghaddam, O'Hara, & Doherty, 2011) etc. For example, Fu (Fu et al, 2013) researched the BM mixture of hexagonal boron nitride and TiO 2 and found that the photocatalytic removal effi ciency of rhodamine B and methyl blue was increased by 15 and 8 times compared with BM TiO 2 alone.…”

“…Simeonidis (Simeonidis et al., ) found the prepared Fe 3 O 4 by BM process without surfactant assisted had larger adsorbing capacity for As (III) and As (V). Zhang (Zhang, Yang, Han, et al., ) discovered that the BM SiO 2 ‐Fe bimetal possessed higher dechlorination activity for 2‐CP degradation even than the Pd‐Fe bimetal. Compared with the chemical displacement precipitation (CSD) method, BM technique is free from employing lots of expensive borohydride for the reduction of metal ions, and easy to prepare the uniformly distributed materials, which is important to maintain the stability of reaction performance.…”

Nonmetallic modified zero-valent iron for remediating halogenated organic compounds and heavy metals: A comprehensive review

“…Silicon dioxide-modified ZVI (SiO 2 -nZVI) offered multiple advantages in improving the dispersibility, reactivity, and reduction of ZVI. Firstly, the silica coating enhanced the stability of ZVI by improving the resistance to oxidation and corrosion, thereby prolonging the operational lifespan [ 96 ]. Secondly, the silica layer provided additional adsorption sites, augmenting the contact area between pollutants and particles, thereby facilitating adsorption [ 97 ].…”

Dry sliding wear investigation on tungsten carbide particles reinforced iron matrix composites

“…In particle reinforced iron matrix composites (PRIMCs), the particle reinforcements often used are carbides, nitrides, oxides because of their good physical and chemical properties [8][9][10]. Other particles are also reported in the literature such as zirconia toughened alumina (ZTA) [11].…”
