Synergizing Multi‐Chemisorption Sites and Micropore Confinement in Porous Carbon for High‐Performance Zinc‐Ion Hybrid Capacitors

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Aqueous zinc‐ion hybrid capacitors (ZICs) bridge the gap between high‐energy batteries and high‐power supercapacitors, yet their performance is fundamentally bottlenecked by the micropore confinement effect in carbon cathodes, which restricts hydrated Zn2+ transport and active site utilization.

Dual‐Phosphidation‐Engineered Ni/NiO Heterojunction Nanoflowers With Synergistic Surface PO43− Group and P Doping Sites for High‐Performance and Low Temperature (−40°C) Supercapacitors

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Nickel oxide (NiO)‐based electrodes with high theoretical specific capacitance can effectively increase the energy density of supercapacitors—the key factor limiting their practical deployment. However, several issues still restrict the production of advanced NiO‐based electrodes.

Atomically Dispersed Platinum Sites Immobilized on NiFe LDH by Controlling Localized Amorphization for Efficient Alkaline Electrocatalytic Hydrogen Evolution

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Platinum (Pt) single‐atom catalyst (SAC) shows great promise for hydrogen evolution reaction (HER), but faces a huge challenge in activity enhancement due to the isolated single‐atom sites. Fabricating support with partially amorphous (pa) structures to realize the synergetic interaction in neighboring single atoms could facilitate H2O ...

Upcycling of Waste Polyethylene Terephthalate Plastics to Fabricate Cobalt–Nickel Metal–Organic Frameworks and Their Phosphides for Efficient Oxygen Evolution Reaction

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves

腐殖酸对蒙脱石吸附镉离子的影响机理研究

Shuitu Baochi Xuebao, 2007
实验研究了腐殖酸存在下重金属元素镉(Cd2 )在蒙脱石表面的吸附过程,对比研究了两种不同腐殖酸对吸附机理的影响。结果表明,重金属离子在蒙脱石表面的吸附作用受介质pH的影响。加入腐殖酸后吸附产生滞后现象,蒙脱石先吸附腐殖酸,之后转变为腐殖酸和蒙脱石共同吸附Cd2 作用,吸附量较单独吸附过程更大。吸附机理与腐殖酸的投加量和投加方式有关。

沉水植物菹草改性后对Cr(Ⅵ)的吸附研究

Gongye shui chuli, 2019
为开发廉价高效去除水中重金属Cr（Ⅵ）污染的生物吸附剂，在以沉水植物菹草固形物作为吸附剂研究的基础上，对菹草进行改性以提高吸附性能，并以其为吸附剂进行吸附实验。改性菹草对Cr（Ⅵ）的去除率最高为99.6%，其对Cr（Ⅵ）的吸附动力学符合准二级动力学方程，吸附等温线符合Langmuir吸附等温线，最大吸附量可达64.5 mg/g，与未改性的菹草相比，最大吸附量提高了84.3%。

改性黄曲霉A5P1对染料酸性蓝25的吸附效果与机理研究

Gongye shui chuli
以黄曲霉A5P1为原料，利用盐酸改性法制成生物吸附剂A5P1acid，用于吸附酸性蓝25（AB25）染料。对A5P1acid吸附的影响因素进行分析，结果表明：染料吸附的最佳吸附剂用量为0.5 g/L，最适pH为2，60 min达到吸附平衡。吸附剂经盐酸改性后，吸附量从137 mg/g提高到182 mg/g，染料去除率提高了32%。通过分析A5P1acid吸附去除AB25的机理，发现吸附过程符合准二级动力学模型，是由化学吸附控制吸附速率；符合Freundlich吸附等温线，吸附属于多层非均相吸附 ...

13X沸石对Ca²⁺吸附性能的实验研究

Gongye shui chuli, 2008
在静态条件下,研究了吸附时间、13X沸石的用量、粒度、流体剪切力、溶液pH、钙离子浓度等因素对13X沸石吸附钙离子性能的影响。结果表明:13X沸石对Ca2+有很好的吸附能力,即使中性条件下表观吸附量就可达到55.60mg/g,并且吸附速度相当快,20min即可达到平衡;合适的流体剪切力可以提高沸石对Ca2+的表观吸附量,此结论证实了流体力化学效应的存在;静态等温吸附过程符合Langmiur吸附等温方程式;13X沸石对Ca2+的吸附机理主要为离子交换吸附和化学吸附,碱性条件下可能发生表面络合和表面沉淀吸附。
