The development of bifunctional electrocatalysts with high performance for both hydrogen evolution reaction (HER) and oxygen (OER) earth-abundant elements is still a challenge in electrochemical water splitting technology. Herein, we fabricated free-standing electrocatalyst the form vertically oriented Fe-doped Ni3S2 nanosheet array grown on three-dimensional (3D) Ni foam (Fe-Ni3S2/NF), which presented activity durability HER OER alkaline media. On basis systematic experiments calculation,...
A solid oxide fuel cell's performance is largely determined by the ionic-conducting electrolyte. novel approach presented for using semiconductor perovskite La0.25Sr0.75TiO3 (LST) as electrolyte creating surface superionic conduction, and authors show that LST can deliver superior power density, 908.2 mW cm-2 at just 550 °C. The prepared materials formed a heterostructure, including an insulating core conducting layer. rapid ion transport along surfaces or grain boundaries was identified...
An SOFC using semiconductor TiO<sub>2</sub> thin film as an electrolyte was designed the energy band theory to prevent short-circuiting problem.
Abstract The alkaline zinc-based batteries with high energy density are becoming a research hotspot. However, the poor cycle stability and low-rate performance limit their wide application. Herein, ultra-thin CoNiO 2 nanosheet rich oxygen defects anchored on vertically arranged Ni nanotube arrays (O d -CNO@Ni NTs) is used as positive material for rechargeable Ni–Zn batteries. As highly uniform provide fast electron/ion transport path abundant active sites, O NTs electrode delivers excellent...
We developed an advanced surfactant-assistant method for the Ir(x)Sn(1-x)O(2) (0 < x ≤ 1) nanoparticle (NP) preparation, and examined OER performances by a series of half-cell full-cell tests. In contrast to commercial Ir black, collective data confirmed outstanding activity stability fabricated (x = 1, 0.67 0.52) NPs, which could be ascribed amorphous structure, good dispersion, high pore volume, solid-solution state Ir-rich surface bi-metal oxides, relatively large size (10-11 nm), while...
To elucidate the ion conduction mechanism, pure oxide structure Sn1–xCexO2−δ (x = 0.05, 0.025) is obtained by doping Ce into SnO2 and combined with Sm0.2Ce0.8O3−δ to form an Sn1–xCexO2−δ–SDC semiconductor-ionic material (SIM), which evaluated as electrolyte membrane assemble fuel cells. Raman measurements revealed that two types of oxygen vacancies, Frenkel vacancy (F-OV) intrinsic (I-OV), simultaneously existed in SIM. Through X-ray photoelectron spectroscopy (XPS) characterization density...
Mixed ion-electron conductor based electrolytes have shown great promise in solid oxide fuel cells (SOFCs) with attractive performance at low temperatures (<600 °C), due to their multi-interface conduction and interfacial...
We reported a facile adjusted method for the synthesis of high surface area nanorod hematite film as photoanode application in water splitting. Crystalline nanorods (EG-α-Fe2O3) are fabricated by electrodeposition Fe2+ precursor solution with addition ethylene glycol (EG) and followed annealing at 450 °C. The modified approach exhibits more uncompact structure than α-Fe2O3 obtained directly electrodepositing on FTO substrate. optical structural characteristics also tested. results infer that...
