α-MoO₃/polyaniline composite for effective scavenging of Rhodamine B, Congo red and textile dye effluent

Abstract

Polyaniline modified MoO3 composites were synthesized via a chemical oxidative polymerization method and employed as a novel adsorbent for Rhodamine B (RhB), Congo red (CR) and textile dye effluent.

Synthesis of MoO3/polypyrrole nanocomposite and its adsorptive properties toward cadmium(II) and nile blue from aqueous solution: Equilibrium isotherm and kinetics modeling

“…Molybdenum trioxide (MoO 3 ), an n ‐type semiconductor, which exists essentially in orthorhombic phase with double MoO 6 octahedral layers, is used in wide range of applications such as electrochemical capacitors, in ceramics and glass production, sensors, and as catalysts. However, the application of MoO 3 or its composite in wastewater treatment process has received scant attention …”

“…However, the application of MoO 3 or its composite in wastewater treatment process has received scant attention. 20 To our best knowledge, no study on adsorptive removal of pollutants using MoO 3 /Ppy nanocomposite has been reported in the litera- TECHNAI-320 KV, Japan), operating at 80 KV was used to investigate the internal morphology and average particle size of the nanocomposite. The residual concentration of Cd 2+ (dithizone method) 21 and NB was determined with T80+ UV/VIS spectrophotometer (PG Instrument Ltd, United Kingdom).…”

Synthesis and characterization of kaolinite/polyaniline nanocomposites and investigating their anticorrosive performance in chlorinated rubber/alkyd coatings

“…Figure 3 shows shift to lower angles in kaolinite diffraction peaks with increasing concentration of PANI in the nanocomposites. This may be due to the expansion produced by the included PANI chains within the kaolinite layers [25,41]. Figure 4 shows the surface morphology and EDX analysis of pure kaolinite and KPAn nanocomposites.…”

Preparation of recyclable MoO3 nanosheets for visible-light driven photocatalytic reduction of Cr(vi)

“…[5][6][7][8] As a n-type semiconductor, molybdenum trioxide (MoO 3 ) can be used in catalytic, optical and electrochemical applications, and compared to other metal oxide materials, MoO 3 has low cost, good structural stability and less toxicity. [9][10][11] For example, assembled-sheets-like MoO 3 was synthesized with a facile heat treatment route and used as an anode for lithium ion batteries, which maintained an improved discharge capacity over 100 cycles with capacity retention of $100%; 12 Wang et al prepared ultrane b-MoO 3 from industrial grade MoO 3 powder via the method of sublimation and discussed its growth mechanism; 13 Pandeeswari et al fabricated nanostructured a-MoO 3 thin lm as a highly selective TMA sensor; 14 by a solution combustion reaction, ultra-porous MoO 3 can be obtained with both excellent photocatalytic and electrochemical properties. 15 Therefore, the development of MoO 3 nanoparticles has consequently increased in recent years.…”
