Electrochemical water splitting into hydrogen and oxygen is a promising technology for sustainable energy storage. The development of earth-abundant transition metal phosphides (TMPs) to catalyze the evolution reaction (HER) TMP-derived oxy-hydroxides (OER) has recently drawn considerable attention. However, most monolithically integrated phosphide electrodes are prepared by laborious multi-step methods their operational stability at high current densities been rarely studied. Herein, we...
Co-catalysis is regarded as a promising strategy to improve the hydrogen evolution performance of semiconductor-based photocatalysts. But developing simple and effective technique achieve optimal synergy between co-catalysts host photocatalysts has been great challenge. Herein, hybrid consisting β-NiS modified CdS nanowires (NiS/CdS NWs) have synthesized via green hydrothermal route using NWs template from thiourea nickel acetate in presence sodium hypophosphite. As result, metal Ni...
Ultrafine molybdenum sulfide (MoS2) nanocrystals are grown on a porous cobalt (Co) foam current collector by atomic layer deposition (ALD) using hexacarbonyl and hydrogen as precursors. When used to catalyze the oxygen evolution reaction (OER), optimal Co@MoS2 electrode, even with MoS2 loading small 0.06 mg cm−2, exhibits large cathodic shift of ca. 200 mV in onset potential (the at which density is 5 mA cm−2), low overpotential only 270 attain an anodic 10 much smaller charge transfer...
Sub-stoichiometric WO3-x has provided an alternative platform to investigate oxygen vacancies in gas sensors based on metal-oxides. We present experimental study the influence of sub-stoichiometric phase upon sensing performance. High-quality nanostructures with several x values (WO3, W19O55, W5O14, W18O49) were synthesized and used fabricate H2S sensors. Temperature programmed desorption (O2-TPD) shows that absorption behaviors as-prepared are affected by vacancies, which played a critical...

A very easy and cost-effective approach to the fabrication of monolithic Co9 S8 water oxidation electrodes (Co@Co9 ), fabricated by one-step hydrothermal treatment commercially available cobalt foam in presence thiourea, is reported. The morphology, crystal structure, microstructure, composition as-fabricated Co@Co9 were examined using scanning electron microscopy (SEM), powder X-ray diffractometry (XRD), transmission microscope (TEM), photoelectron spectroscopy (XPS), their electrochemical...

Coupling two-dimensional (2D) electroactive species with 3D carbon substrates is a very promising strategy to fabricate advanced electrodes for high-performance flexible electrical energy storage devices. However, the intractable coupling between them has prevented wide applications of such strategy.

Abstract To obtain high‐performance magnetic sheet with high initial permeability and low loss for wireless charging system, Ni–Zn–Cu ferrite ceramics a chemical formula of Ni 0.6 − x Zn 0.4 Cu Fe 2 O 4 ( = 0–0.30) were prepared by traditional solid reaction‐sintering method. As expected, the doped 2+ ions could effectively reduce sintering temperature increase density ferrites. With increasing doping amount , coercivity, saturation magnetization, Curie resultant ferrites decreased. 0.15,...
