Abstract null null Structural doping is often used to prepare materials with high oxygen-ion conductivity and electrocatalytic function, but its wider application in solid oxide fuel cells (SOFCs) is still a major challenge. Here, a novel approach to developing materials with fast ionic conduction and high electrocatalytic activity is reported. A semiconductor-ionic heterostructure of perovskite Ba0.5Sr0.5Fe0.8Sb0.2O3-δ (BSFSb) and fluorite structure Sm0.2Ce0.8O2-δ (SDC) is employed. The BSFSb-S...

Abstract null null A comparative study is performed to investigate the electrochemical performance of the low-temperature ceramic fuel cells (CFCs) utilizing two different novel electrolytes. First, a perovskite semiconductor SrCo0.3Sn0.7O3-δ was used as an electrolyte in CFCs due to its modest ionic conductivity (0.1 S/cm) and demonstrated an acceptable power density of 360 mW/cm2 at 520 °C. The performance of the cell was primarily limited due to the moderate ionic transport in the electrolyte...

Abstract Introducing multiple-ionic transport through a semiconductor-electrolyte is a promising approach to realize the low-temperature operation of SOFCs. Herein, we designed and synthesized a single-phase Ce-doped BaCo0.2Fe0.3-xTm0.1Zr0.3Y0.1O3-δ semiconductor-electrolyte possessing triple-charge (H+/O2−/e−) conduction ability. Two different compositions are synthesized: BaCo0.2Fe0.3-xCexTm0.1Zr0.3Y0.1O3-δ [x = 0.1–0.2]. The 20% doped Ce composition exhibits an outstanding oxide-ion and proto...

Abstract Layer-structured lithium cobalt oxide (LCO) is one of promising electrode materials for secondary aqueous lithium-ion batteries, yet the effect of structural proton insertion in LCO in neutral aqueous electrolytes cannot be ignored. Present study investigates the electrochemical performance of polycrystalline spherical LCO in neutral aqueous saturated Li2SO4 solution. Herein, we for the first time demonstrate the dependence of LCO stability on the discharge cutoff potential. The applied...

Abstract Low-temperature solid oxide fuel cells (LT-SOFCs) is a promising fuel cell technology but often suffers from low ionic conductivity of the electrolyte. Herein we develop a solid electrolyte with high ionic conductivity based on thulium (Tm) doped composite, Sr0.1TmxCe0.9-xO2-δ [x = 0.1] having a cubic fluorite structure. The fuel cell utilizing Tm-doped SrCeO2-δ electrolyte achieved the power output of 682 mW/cm2 at 550 °C with an open-circuit voltage (OCV) of 1.03 V; whereas the fuel c...

The introduction of heterostructure is a new approach in gas sensing due to its easy and quick transport of charges. Herein, facile hydrothermal and solid-state techniques are employed to synthesize α-Fe2O3/Nb2O5 heterostructure. The morphology, microstructure, crystallinity, and surface composition of the synthesized heterostructure are investigated by SEM, TEM, XRD, XPS, and BET analyses. The mutual incorporation of α-Fe2O3 nanorods with Nb2O5 interconnected nanoparticles (INP) for the success...

Nanocomposites can offer a platform to conjugate biorecognition features of aptamer with unique size-dependent properties of a given material, which can autoprobe the binding event based on their electroactive characteristics. Herein, we design electroactive switchable aptamer probes based on co-doped single-phase semiconducting materials employing the cyclic voltammetry method to record the current signal at each step of electrochemical characterization. To do so, we utilized a facile hydrother...

Abstract This study reported the chemical reduction method based synthesis of ionic liquid (IL) functionalized nano-zerovalent cerium (nZVCe) for the degradation of carbamazepine (CBZ) and colorimetric detection of H2O2. Carbamazepine is an important class of emerging water pollutants while H2O2 is produced as a major by-product by living organisms during metabolism. The synthesized IL-nZVCe showed high efficiency towards CBZ degradation and H2O2 detection. The use of advanced characterization t...
