This report presented an effective way to synthesize MnO2/graphene nanocomposites using the plasma electrolysis method for photocatalytic degradation of methyl orange dye in water. The morphology, structure, and chemical composition materials were investigated through scanning electron microscopy (SEM), Raman spectra, Fourier-transform infrared (FTIR) spectroscopy, respectively. SEM results sho...

Glyphosate, one of the organophosphate herbicides, has been widely used in the word. The removal of glyphosate was comparatively investigated by MnO2 oxidation, electrochemical oxidation, and electrochemically assisted MnO2 oxidation (electro-MnO2) processes. The effects of MnO2 dosage, current density, and solution pH on glyphosate removal and Mn release were examined. The results indicated th...

Water pollution with dye effluents from different industries is a broadly established environmental and health problem that needs serious attention. In this study, making use of Acacia nilotica seed extract, greenly synthesized MnO2 nanoparticles were loaded on the surface biochar derived palm waste (MnO2/PF), specific areas 70.97 m2/g. Batch experiments adopted, aiming to evaluate performance ...

The our main goal of the present research is evaluating the performance of MnO2 nanoparticles-AgX zeolite composite as a novel adsorbent catalyst for the decontamination reactions of two most known sulfur mustard simulants; 2-chloroethyl phenyl sulfide (2-CEPS), 2-chloroethyl ethyl sulfide (2-CEES) at room temperature and monitoring by Gas chromatography flame ionization detector (GC-FID) and G...

composite electrodes of polyaniline/mno2-multi walled carbon nanotube (pani/mno2-mwcnt), mno2-mwcnt nanocomposites and mwcnt was produced by the in situ direct coating approach. the supercapacitor performance of the nanocomposites was studied by fourier transform infrared (ft-ir) spectroscopy and scanning electron microscopy (sem). the electrochemical properties of electrodes were also investig...

Pre-treatment is normally required to reduce or control the fouling of ultrafiltration (UF) membranes in drinking water treatment process. Current pre-treatment methods, such as coagulation, are only partially effective to prevent long-term fouling. Since biological activities are a major contributor to accumulated fouling, the application of an oxidation/disinfection step can be an effective c...

A novel γ-MnO2 catalyst obtained by selective removal and other traditional MnO2 catalysts (α-, β-, δ-MnO2) were studied for their catalytic performance in toluene combustion. The new γ-MnO2 catalyst showed the best catalytic activity owing to its three-dimensional macroporous and mesoporous morphology and the γ-MnO2-like structure.

Various nanoparticles have been developed for bio-applications. However, nanocomposites particles, (NCPs) with effective and ability to sensing cholesterol, are still needed. Herein, we present new cholesterol pH-responsive NCPs as sensor particles promote sensitivity. The traditional method of mixing grinding was used fabricate the oxides magnesium manganese MgO–MnO2 different ratios. Structur...

The nanocomposite materials of poly(3,4-ethylenedioxythiophene)/graphene oxide (PEDOT/GO), poly(3,4-ethylenedioxythiophene)/MnO2 (PEDOT/MnO2), and poly(3, 4-ethylenedioxythiophene)/graphene oxide/MnO2 (PEDOT/GO/MnO2) were successfully prepared by facile and template-free solution method. The structure and morphology of nanonanocomposites were characterized by Fourier transform infrared spectros...
