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

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.

Gongye shui chuli, 2006 采用内电解—MBR工艺对制药废水进行处理研究，内电解法作为预处理主要降低有机污染物污染负荷，同时可以转化难降解有机物抑制的毒性，提高废水的可生化性。MBR工艺具有污泥浓度高、抗冲击负荷能力强、降解充分、降解速率高，对难降解物质也可使之分解去除的特点。通过试验研究得出在原水COD为12000mg/L左右时，内电解对该废水COD去除率可达40%左右，MBR的出水可使COD<300mg/L。

Gongye shui chuli, 2020 考察了铁碳微电解+A/O组合工艺对实际有机硅废水的处理过程。结果表明，铁碳微电解降解符合一级反应动力学；组合工艺对COD总去除率达到了96%，出水达到《污水综合排放标准》（GB 8978—1996）表4的一级标准，说明该组合工艺具备稳定达标运行的能力。三维荧光分析表明，原水中存在难降解峰峰A、峰B，微电解和厌氧处理后出现了易降解峰峰C和峰D，最终出水中仅保留与原水强度相当的峰B。
