Gongye shui chuli, 2012 采用碳酸钙沉积法对单宁酸在冷却水中的阻垢性能进行了试验研究,考察了温度、碱度、硬度和金属离子等因素对其阻垢性能的影响。结果表明,单宁酸对碳酸钙具有较好的阻垢性能,当温度低于70℃、单宁酸质量浓度为20 mg/L时,阻垢率可达到72%;高碱度和高硬度条件下,单宁酸对碳酸钙的阻垢率会有一定程度的下降;Fe3++对单宁酸的阻垢有抑制作用,而Cu2++虽对单宁酸的阻垢具有协同作用,但会加大管道腐蚀,所以Cu2++浓度不宜过高。

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Balancing low iridium dosage and robust anodic stability remains a critical hurdle for practical proton exchange membrane water electrolysis (PEMWE). Although IrRuOx offers a cost‐effective alternative, current systems still suffer from the dual dilemma of excessive noble‐metal reliance and inadequate long‐term durability. Herein, we developed

Gongye shui chuli, 2006 在酸性条件下，以过氧化氢还原氯酸钠制备高纯度二氧化氯进行了实验研究。实验数据表明，反应的温度和酸度对反应结果影响比较大，预先加入氯离子可以起到强化作用。实验得出了最佳的反应条件：真空度为0.010 MPa，温度为80℃，硫酸浓度为4 mol/L，过氧化氢与氯酸钠的质量比为0.190。在此条件下，能够保证二氧化氯纯度为100%，且氯酸钠转化率大于88%，二氧化氯收率在90%以上。解决了目前制备方法中二氧化氯纯度与氯酸钠转化率、二氧化氯收率不能同时兼得的问题。

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT To achieve high‐value utilization of spent catalysts, we recovered copper (Cu) from Cu‐bearing spent catalysts via acid‐base leaching to fabricate CuO and systematically studied how calcination temperature affects their microstructure and humidity‐sensing performance. Characterizations show that CuO‐500 (calcined at 500°C) has a large specific

Bidirectional Interfacial Chemical Regulation Enables Durable Aqueous Zn‐I2 Batteries
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐I2 batteries hold great promise for large‐scale energy storage, yet their practical deployment is hindered by coupled interfacial instabilities at both electrodes, where Zn‐anode parasitic reactions and cathodic polyiodide shuttle mutually aggravate each other.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Sodium‐ion batteries (SIBs) offer a promising, cost‐effective alternative for large‐scale energy storage due to the abundance of sodium. However, their practical deployment is challenged by sluggish interfacial kinetics and unstable interphase formation, which severely limit performance across wide temperature ranges. Here, we demonstrate that
