High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

铁碳微电解强化厌氧产氢及硫酸盐还原

open access: yes, 2016
厌氧生化处理技术在处理废水的同时能够实现能源和资源的有效回收,在应用范围、成本与生态方面都具有显著的特点。但是,该技术自身也存在着诸多缺点。专性厌氧菌世代周期长,而且对环境条件要求严格,为了满足厌氧处理正常运行的要求,常会增加额外的费用和工作量。厌氧微生物对有毒物质比较敏感,当废水中含有高浓度的含硫化合物尤其是硫酸盐时,生成的硫化物会对正常的厌氧过程造成不利的影响。因此,有必要研究强化厌氧产能和硫酸盐还原的新方法,这对厌氧生物处理技术的推广、废水的有效处理和能源化都具有重要的意义。针对以上问题 ...

强化混凝法去除腈纶废水中COD的机理研究

open access: yesGongye shui chuli, 2018
进行了强化混凝法去除腈纶废水中COD的研究。结果表明,铁碳微电解预氧化可提高混凝处理效果。通过对分子质量分布、Zeta电位及核磁共振波谱的测定发现,铁碳微电解的氧化作用可导致大分子有机物降解为小分子有机物,小分子有机物矿化,因此提高了分子质量>50 ku和<3 ku的有机物去除率;微电解产生的Fe2+有电性中和作用,使Zeta电位降低,强化混凝效果;微电解的氧化作用主要破坏酯类和醚类结构。

Pyrolysis‐Engineered Fe/Mn‐ZIF Catalysts: Balancing Activity, Selectivity, and Stability for the Oxygen Reduction Reaction

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the
