Li4Ti5O12/C–C (using glucose and polyurethane as double carbon sources) microspheres with particle sizes ranging from 200 to 300 nm were fabricated with a spray drying method, followed by a solid-state reaction. Compared with pure Li4Ti5O12 and Li4Ti5O12/C (using glucose as single carbon source), Li4Ti5O12/C–C exhibits higher rate performance and b...

AbstractA mathematical model based on a generalized Maxwell–Stefan equation has been developed to describe multicomponent ion and water transport inside a cation-exchange membrane. This model has been validated using experimental data and has been used to predict concentration profiles, membrane potential drop, and transport numbers of ions and wat...

Cobalt/iron oxide nanoparticles (CFO/NPs) were fabricated with a facile solid combustion method and decorated on polyaniline-derived porous N-doped carbon nanosheets. The N-doped carbon nanosheets provide a pathway for charge transfer and act as defensive layers to avoid the agglomeration of nanoparticles. The decoration of CFO nanoparticles on por...

Herein, we report the electrochemical water oxidation efficiency of nano-Co3O4 catalyst samples obtained by the thermal decomposition of Co(NO3)2·6H2O at various temperatures (320, 420, 520, and 620 °C). The structural and morphological details of the synthesized samples were determined by employing X-ray diffraction, scanning electron microscopy, ...

AbstractPreviously optimized anatase and nitrogen-doped anatase TiO2 coatings have been grown by low-frequency plasma-enhanced chemical vapor deposition (PECVD) on different kinds of substrates at low plasma power (64 W) and high plasma power (100 W) for photo-electrochemical studies. Nitrogen-doped TiO2 layers exhibit better photoactivity and also...

The sub-micrometer lead powders were electrodeposited on a mild steel (MS) substrate in PbS-containing (10–50 mM) choline chloride–urea deep eutectic solvent (ChCl–urea DES) at 353 K and 2.5 V. The electrochemical behaviors of the Pb(II)/Pb on MS and glass carbon electrodes were determined by cyclic voltammetry and chronoamperometry measurement. It...

The poly(diphenylamine) and poly(4,4′-diaminodiphenyl ether) represent poor current signals and activity. This paper has aimed to synthesize the poly(diphenylamine-co-4,4′-diaminodiphenyl ether) for the first time to overcome these deficiencies. Regarding the reaction circumstances, the potential range of 0–1000 mV was applied to the 1:1 mixture of...

AbstractThermal runaway is posing big threat towards common electrochemical devices, such as lithium ion batteries and supercapacitors. It is caused by heat accumulated within electrochemical device and can cause devices to lose functionality, shorten service-life, or even cause hazardous fires and explosions. One effective approach to tackle therm...

AbstractReversible oxygen reduction/evolution reaction (ORR/OER) electrodes with non-precious metal catalysts are essential for the larger scale development of rechargeable metal–air batteries and regenerative fuel cells. Here, an investigation of the catalyst layer morphology is presented with respect to the bifunctional ORR/OER activity and durab...

AbstractTwo MgCo2O4 nanostructures in different morphologies have been synthesized by using two different structure-directing agents (urea (U) and nitrilotriacetic acid (NTA)) as new catalysts for water oxidation reactions. The properties of these nanostructures were discovered and characterized by a combination of analytical techniques, being TEM,...
