掺杂Fe-PbO₂电极的制备及其对酚类废水降解性能研究

Gongye shui chuli, 2012
采用阳极恒电流电沉积技术制备不锈钢基PbO2电极及掺杂Fe-PbO2电极。采用XRD、SEM、EDS等方法对电极的物相结构、表面形貌、元素组成进行了表征和分析,对PbO2电极及掺杂Fe-PbO2电极电催化氧化酚类模拟废水的降解率进行研究,结果表明:掺杂Fe-PbO2电极表面形貌及衍射强度发生不同程度的改变,添加的Fe3+可能进入了表层内部,掺杂Fe-PbO2电极较普通的PbO2电极对酚类废水具有更好的电催化氧化降解性能。

Synergistic Electronic Modulation of 1T/2H Mixed‐Phase MoS2 via Phosphorus Insertion and Carbon Coating for Enhanced Acidic Hydrogen Evolution Kinetics

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT MoS2 is considered a promising electrocatalyst for the hydrogen evolution reaction (HER) because of its low cost and excellent stability. However, its practical application is severely limited by the scarcity of edge active sites and poor intrinsic electrical conductivity.

不均匀电场SF₆/N₂混合气体击穿特性的实验研究

Gaoya dianqi, 2016
文中对SF6/N2混合气体在不均匀场下的击穿特性展开研究,通过测量棒—板电极在不同电极间距、混合比、压强下的正、负极性击穿电压值,分析电场不均匀度及气体压强对SF6/N2混合气体极性效应的影响。研究结果表明:在0.1 MPa时,击穿电压随着电极间距的增大而增大,N2负极性的击穿电压高于正极性的击穿电压,在电极间距为12 mm时,负极性击穿电压是正极性击穿电压的1.71倍,而SF6气体与N2极性效应相反,表现为正极性的击穿电压略高于负极性的击穿电压;电极间距为4 mm时,随气体压强的升高负极性击穿电压增大,

Decorating Graphite Felt Electrode With Uniformly M‐Nx Functionalized Carbon Nanosheets for High‐Performance Vanadium Redox Flow Batteries

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Vanadium redox flow batteries show considerable promise for energy storage, yet their overall performance is still hindered by the limited electrochemical activity of graphite felt (GF) electrodes. Herein, using folic acid and metal salts as precursors, M–N–C functionalized carbon nanosheets (M–NC, M=Co, Fe, and Ni) were prepared via a ...

Construction of Hydrophilic Percolation Networks in Physical Wet‐Mixed Carbon Electrodes for High‐Rate Capacitive Deionization

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Capacitive deionization (CDI) using activated carbon (AC) electrodes holds great promise for seawater desalination, yet its practical application is severely constrained by the intrinsic hydrophobicity of carbon surfaces. Herein, we propose a solid‐state superhydrophilic modulation strategy that physically wet‐mixes superhydrophilic MOF ...
