Abstract Atomically dispersed transition metals confined with nitrogen on a carbon support has demonstrated great electrocatalytic performance, but an extremely low concentration of metal atoms (usually below 1.5%) is necessary to avoid aggregation through sintering which limits mass activity. Here, salt‐template method fabricate densely populated, monodispersed cobalt nitrogen‐doped graphene‐like reported, and achieving dramatically higher site fraction Co (≈15.3%) in the catalyst...
The application of highly ordered TiO2 nanotube arrays (NTAs) for energy storage devices such as supercapacitors has been attractive and great interest owing to their large surface area greatly improved charge-transfer pathways compared those nonoriented structures. Modification the semiconductor nature is important its in constructing high-performance supercapacitors. Hence, present study demonstrates a novel method involving fabrication self-doped NTAs by simple cathodic polarization...

Vanadium oxides are a promising class of cathode materials for rechargeable aqueous zinc-ion batteries (ZIBs). However, the intrinsically low electrical conductivity and unstable structure vanadium often lead to fast performance degradation. In this work, we report on potassium-rich preintercalated oxide (K1.1V3O8) as high-performance material ZIBs. The K1.1V3O8 exhibits high specific capacity 386 mAh g–1 at 0.1 A good long-term cycling stability with retention 114.9% (180.7 g–1) after 10...
Recently, wearable and breathable healthcare devices for air filtering real-time vital signs monitoring have become urgently needed since virus particulate matter (PM) cause serious health issues. Herein, we present a trap-induced dense monocharged hybrid perfluorinated electret nanofibrous membrane (HPFM) highly efficient ultrafine PM0.3 removal with an efficiency of 99.712% under low pressure drop (38.1 Pa) high quality factor 0.154 Pa-1. Furthermore, recyclable multifunctional mask is...
The water flooding potential of the target reservoir in Nanpu 3–2 zone has been distinctly declining year by year, making it difficult to achieve effective development. There is an urgent need explore alternative displacement methods improve oil recovery. Based on petrophysical characteristics reservoir, artificial cores were made. oil-saturated prepared according actual forming. After fully displacing with brine, displaced N2, CO2, and hydrocarbon gas, respectively, effectiveness three...
A novel method involving the fabrication of Mo-W mixed oxide (MoxW1-xO3) is proposed to modify modest reaction kinetics and poor cycling stability MoO3 material. By a simple coelectrodeposition method, series MoxW1-xO3 oxides deposited on TiO2 nanotube array substrate. Because differences between Mo6+ W6+ in nature, there significant distortion existing oxides, leading their decreased crystallite size enlarged lattice space, which facilitates ion diffusion solid. As results, show much better...
Polytetrafluoroethylene (PTFE) is a fascinating electret material widely used for energy harvesting and sensing, an enhancement in the performance could be expected by reducing its size into nanoscale because of higher surface charge density attained.
