Synthesis and characterization of carbon xerogel/graphene hybrids as adsorbents for metronidazole pharmaceutical removal: Effect of operating parameters

Quick removal of metronidazole from aqueous solutions using metal–organic frameworks

“…14,15 This versatile and cost-effective method is usually characterized by low energy consumption with a limited use or production of harmful products and auxiliary materials. 16,17 Various adsorbents have been utilized for MNZ adsorption, among which pristine and modified sepiolite, 18 microorganism-activated carbon, 19 carbon-based substances, 19,20 a Department of Civil and Environment Engineering, Shahrood University of urea and melamine-modified MOF MIL-101-(Cr), 4 carbon xerogel/ graphene hybrids, 21 Fe 3 O 4 /cellulose nanocomposites, 22 the Fe 3 O 4chitosan nano-adsorbent 23 and the PPY-PANi copolymer 24 can be mentioned.…”

Recycling and valorization of LDPE: direct transformation into highly ordered doped-carbon materials and their application as electro-catalysts for the oxygen reduction reaction

“…This demonstrates, once again, the effect of the generated pressure since other metal-free polymers carbonized at atmospheric pressure present higher I D /I G values even at higher temperatures. 51,52 However, it should be noted that the I D /I G ratio linearly increases with increasing L c ; thus, to evaluate the modification of the graphitization degree by the metal doping, the D band width (W D ) is considered. Note that as expected, the D band width (Table 2) decreases in the order C > C-Fe > C-Ni > C-Co, following the same trend observed for L c and d (002) obtained from the XRD results, denoting an increase of the graphitization degree in this sense.…”

Rational design of in‐situ‐modified resorcinol formaldehyde aerogels for removing chlortetracycline antibiotics from aqueous solutions

“…[31] In recent years, various organic, inorganic, and hybrid aerogels have been fabricated. [32][33][34][35][36][37][38][39] As one of the compelling cases, resorcinol formaldehyde (RF) aerogel that is composed of interconnected structure at the nanometer scale. Throughout the aerogel production methods, general properties of aerogels depend on two ratios: resorcinol/catalyst (R/C) and resorcinol/water (R/W) molar ratio.…”
