Gongye shui chuli重金属炭基吸附材料再加工制备超级电容器电极，是实现废弃炭材料回收再利用的有效途径。1 200 ℃热解炭（BC）对水中Cu（Ⅱ）和Pb（Ⅱ）的吸附容量、效率及去除率远远超过市售活性炭。5 min内，BC对Cu（Ⅱ）、Pb（Ⅱ）的去除率接近100%，可作为一种潜在的超快速废水重金属吸附剂。吸附过程更符合拟二级动力学及Langmuir等温线模型，以单分子层化学吸附为主。由Langmuir等温线模型计算BC吸附Cu（Ⅱ）和Pb（Ⅱ）的最大吸附容量分别为（176.35±5.02）、（174.61±4.93）mg ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The low energy density of sodium‐ion batteries (SIBs) remains a major barrier to their large‐scale deployment. Alloy‐based anodes represent a promising class of materials owing to their high specific capacity and low operating potential for sodium storage. However, their practical application is hindered by severe volume expansion upon cycling.

Gongye shui chuli, 2018 采用活性炭纤维作为电极材料，经过盐酸改性后研究其电吸附去除水溶液中盐离子的效果。研究结果表明，工作电压越高去除效率越好；不同盐离子的吸附量与其平衡浓度之间的关系均较好地符合Freundlich等温式，Lagergren准二级动力学方程能很好地描述电吸附过程的整个阶段；含有不同价态的盐离子溶液，价态越高吸附效果越好；而含有同价态的盐溶液，电吸附更偏向选择水合半径小的离子，且价态大于水合半径对电吸附效果的影响。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Heteroatom coordination regulation is an effective strategy to enhance Fenton‐like catalysis of single atom catalysts, yet its impact on the local microenvironment of active sites still requires in‐depth investigation. Herein, Cl2–Fe–NC catalysts with axial Cl coordination are prepared.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Nickel‐based materials are highly remarkable as promising transition metal catalysts for the electrochemical hydrogen evolution reaction (HER) in alkaline electrolytes. However, their electrochemical performance is limited by an unfavorable d‐band energy (Ed) level. Herein, we showcase an effective lattice‐strain strategy to modulate the Ed of

Gongye shui chuli, 2001 论述了荷电微孔滤膜对水中负电颜料达旦黄的吸附性能。实验证明,水的pH值在 .0～ 9.0之间,膜对达旦黄的吸附性能不受pH值的影响,但当pH值大于9.0时,其吸附性能减弱。水中氯化钠不影响膜的吸附性能。一般条件下,孔径为0.2μm的荷电微孔滤膜对达旦黄的吸附容量为10mg/cm3。这表明荷电微孔滤膜在工业废水处理中对负电颜料的分离有着广阔的应用前景。
