Abstract null null Symmetrical solid oxide fuel cells based on yttrium-stabilized zirconia (YSZ) electrolyte and Sr2Fe1.5Mo0.5O6-δ (SFM) electrode are prepared via phase-inversion and impregnation processes. The YSZ symmetrical electrolyte support is constructed using two porous frameworks and one thin-dense-membrane via phase-inversion combined with drip-coating techniques. SFM is infiltrated into the porous frameworks of the symmetric YSZ support to work as electrodes. Nanoscale Pr6O11 catalys...

Abstract null null Polythiophene and other conductive polymers can be obtained by electropolymerization from various solvents, of which boron trifluoride diethyl etherate (BFEE) is preferably used. In this solvent, electropolymerization can be performed at significantly lower potentials and therefore milder conditions, from which polymers with improved properties result. However, their quality cannot easily be reproduced. We discovered the mechanism behind the decreased initial oxidation potenti...

Abstract null null Carbon corrosion represents one of the most critical degradation mechanisms within state-of-the-art polymer electrolyte membrane fuel cells. Its most prominent consequences include the loss of electrochemical active surface area (ECSA), porosity, and electrical contact within the electrode. The present study seeks a detailed understanding of the dependence between the polarization performance losses and the individual loss terms, both as a function of the amount of corroded ca...

Abstract null null For lithium–sulfur (Li–S) batteries to be used in practical applications, the low conductivity of elemental sulfur and the shuttle phenomenon need to be overcome together with the preparation of cathode material of a high sulfur content. Herein, we report a two-dimensional (2D) delaminated MXene-wrapped sulfur composite (S@d-MXene) synthesized via facile electrostatic self-assembly. The ultrathin and flexible 2D MXene wrapping of sulfur particles provides a pathway for lithium...

Abstract null null Transition metal oxides as promising electrode materials have been widely explored for lithium-ion batteries (LIBs). Nonetheless, their practical applications are still hindered by their modest electronic conductivities, poor rate properties, and huge volume changes/rapid capacity degradation over the ceaseless delithiation/lithiation processes. To address the issues, we firstly encapsulate nano-dimensional Ni0.5Co0.5MoO4 with a solid solution structure in the carbon nanofiber...

Abstract null null The charge storage and distribution in a porous conductive carbon material, in the presence and absence of electrolyte, are studied using the Poisson-Nernst-Planck equations for the first time in the literature. By solving the Laplace equation, it is found that the charge distribution inside the pores is negligible in the absence of the electrolyte. In the presence of cations and anions of the electrolyte inside the pores, the charge distribution on the pore surfaces and ionic...

Abstract null null Fabrication of perovskite solar cells (PSC) in ambient environment or high relative humidity (RH) condition may assist in reducing the production cost and simplifying the fabrication process. However, processing PSC in high-humidity faces major challenges related to degradation of perovskite material and formation of low-quality film. To this end, we focus on improving the perovskite film quality by introducing 4-tert-butylpyridine (TBP) as additive to manipulate the morpholog...

Abstract null null Porous carbon materials are important in electrochemical applications due to their unique nanostructures and remarkable physicochemical stability. In this work, nitrogen-doped porous carbons were fabricated using the self-templating networks of pyridyl conjugated microporous polytriphenylamine. The prepared nitrogen-doped porous carbons show a high content of nitrogen (4.6–11.5 wt%) with fine performance of CO2 capture (store 14.0–17.0 wt% at 273 K and 1 bar) and high specific...

Abstract null null Amorphous catalysts with abundant defects are attractive for electrocatalytic water splitting. In this work, amorphous Fe0.95S1.05 (a-FeS) nanorods are synthesized by a facile solvothermal method using octylamine solvent and employed as a low-cost and highly active electrocatalyst towards efficient hydrogen evolution reaction (HER). The capped octylamine molecules are responsible for formation of the amorphous structure. The disordered atomic arrangement with plenty of unsatur...

Abstract null null A nanostructured samarium oxide electrode was constructed by electrodeposition onto the surface of a gold electrode on SiO2/Si wafer. The samarium oxides electrode's surface morphology was investigated by scanning electron microcopy showing a quasi-monodispersed nanoplatelets like structure. X-rays diffraction analysis demonstrated a mixture of monoclinic and hexagonal phases while the X-rays photoelectron spectroscopy indicated the co-existence of both Sm2+ and Sm3+ species i...
