Abstract The electrochemical properties of metal oxides are very attractive and fascinating in general, making them a potential candidate for supercapacitor application. Vanadium oxide is particular interest because it possesses variety valence states also cost effective with low toxicity wide voltage window. In the present study, vanadium nanorods were synthesized using modified sol–gel technique at temperature. Surface morphology crystallinity studies carried out by scanning electron...
In the present work, we report synthesis of surface modified activated carbon (AC). The have been by using silver nanoparticles. process is simple, cost effective and environment friendly. modified-AC powders characterized X-ray diffraction, scanning electron microscopy area pore size measurements. electrochemical performance prepared materials tested fabricating symmetric configuration EDLC magnesium-ion based polymer electrolytes. cells cyclic voltammetry, impedance spectroscopy...
Ionogels are an attractive class of materials for smart and flexible electronics prepared from the combination a polymer ionic liquid which is entrapped in this matrix. provide continuous conductive phase with high thermal, mechanical, chemical stability. However, because higher percentage liquids it difficult to obtain ionogel conductivity mechanical stability, very important application point view. In work, films flexibility, excellent conductivity, exceptional stability were using...
Single-stage, catalysis-assisted plasma technology is a new concept developed to decompose carbon tetrachloride (CCl/sub 4/), one of the greenhouse gases, and reduce reaction by-products at same time. A laboratory-scale reactor used packed-bed with 1-mm spherical BaTiO/sub 3/ pellets. The configuration employed unique one-stage catalysis/plasma process in which pellets were coated or impregnated by active catalysts such as Co, Cu, Cr, Ni, V. power supply for these experiments was either...

<title>Abstract</title> Electrocatalytic seawater splitting seems to be the most promising and urgent demand strategy for clean hydrogen energy production. Utilizing low-cost electrocatalysts is pivotal in economy, as can made highly efficient more economical. To meet these expectations, we proposed using lithium-ion battery waste, black carbon mass left over from hydrometallurgical metal recovery, an stable electrocatalyst oxygen evolution reaction (OER) performed alkaline media. The...
