Organic−inorganic hybrid membranes based on poly(vinyl alcohol)−SiO2 were prepared under acidic and basic conditions, in which sulfonic acid groups introduced at the inorganic segment. These extensively characterized for their morphology, intermolecular interactions, thermal mechanical stability, physicochemical properties using scanning electron microscopy (SEM), transmission (TEM), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), differential calorimetry (DSC), dynamic...
This review addresses the basic route used to synthesize composite membrane materials. The main emphasis has been given preparation procedures of inorganic materials, their modifications and composites with perfluorinated hydrocarbon polymers. properties are addressed respect fuel cell applications.
Herewith we are reporting a half-cell study of ceria electrode material made by uniform doping silver and platinum nanoparticles for high performance supercapacitor applications. The hydrothermally synthesized had 5–7 nm size doped particles decorated on graphene sheet. electrodes were prepared dip coating. measured specific capacitance the neat Gr–CeO2 was found to be 208 F g–1 at 1 A current density. Doping with platinum, large increase in observed. Silver gave 1017 density, 5-fold...
Due to energy crises in the future, much effort is being directed towards alternate sources. Solar accepted as a novel substitute for conventional sources of energy. Out long list various types solar cells available on market, solid state photoelectrochemical (SSPECs) and dye sensitized (DSSCs) are proposed an alternative costly crystalline cell. This review provides common platform SSPECs DSSCs using polymer electrolyte, particularly polyethylene oxide (PEO)-based electrolytes. numerous...
Benchmarking of a polyethylene–styrene–divinylbenzene-based interpolymer cation exchange membrane for vanadium redox flow batteries.
The development of high-performance membranes to address the issue vanadium ion crossover in redox flow batteries (VRFB) is a significant area focus. Current commercial perfluorinated suffer from economic impracticality, poor selectivity, and electrolyte leakage. In this report, we present composite membrane called PANI-Si@PP, which exhibits exceptional selectivity for protons over ions due Donnan exclusion by positively charged polyaniline backbone presence well-defined proton conductive...
Poly(vinyl alcohol)–silica composite proton-exchange membranes were prepared by a sol–gel process in acidic conditions using aminopropyltriethoxysilane as an inorganic precursor and functionalized with phosphonic acid. Phosphorylation of the was confirmed Fourier transform infrared (FTIR) spectroscopy ion-exchange capacity (IEC) studies. These extensively characterized for their thermal mechanical stabilities, physicochemical electrochemical properties thermogravimetric analysis (TGA),...
Li-ion battery anodes made of SnO2 nanoparticles and a TiO2-supported nanocomposite formed equimolar amounts the Sn Ti oxides were investigated, respectively. By limiting voltage window charge/discharge cycles to range 50 mV–1.0 V, both SnO2-based anode SnO2/TiO2-based show improved cycling stability. Compared nanoparticle based anodes, TiO2-support-SnO2 exhibit better cyclability higher Coulombic efficiency. During first lithiation process, Li+ conducting LixTiO2 is in SnO2/TiO2 composite,...
The electrospinning of chitosan remains challenging due to its rigid crystalline structure, insufficient viscosity, and limited solubility in common organic solvents. This work presents a “smart” modification that allows irrespective molecular weight or deacetylation value without blending with synthetic polymers. A novel derivative, namely 2‐nitrobenzyl‐chitosan (NB), at various molar compositions chitosan:2‐nitrobenzaldehyde (1:1 (NB‐1), 1:0.5 (NB‐2), 1:0.25 (NB‐3)) was synthesized by the...
Rational design of active and stable bifunctional electrocatalysts for the generation hydrogen oxygen is crucial clean renewable energy. Herein, we developed a robust method preparation from RuO 2 phosphomolybdic acid (PMA)-encapsulated multi-walled carbon nanotubes (MWCNT). It involves low-temperature thermal encapsulation PMA followed by anchoring at sites ion exchange. @PMA/MWCNTs showed an exceptionally low overpotential 41 mV evolution reaction (HER) with Tafel slope 71 d −1 ec in...
