针对微米级零价铁（mZVI）表面钝化层抑制电子传递的问题，采用硅钨酸（STA）作为电子介体，构建了STA/mZVI协同还原体系，以提高mZVI传递还原地下水中六价铬的速率。通过批量实验，系统考察了STA投加量、mZVI用量、初始pH、Cr（Ⅵ）浓度及共存阴离子对反应效能的影响。研究表明：在优化条件〔Cr（Ⅵ）=7 mg/L，STA=0.077 g/L，mZVI=1.5 g/L〕下，STA/mZVI体系在60 min内对Cr（Ⅵ）的去除率达96.8%，准一级动力学常数k₁为0.054 min-1 ...

Redox Reaction and Dissolution Analysis for Hollow C Nanospheres Comprising N‐Doped C Framework With Abundant Ni–Co Heteronuclear Catalysts for Highly Durable K‒Te Batteries

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Tellurium (Te), emerging as a promising alternative to sulfur (S) and selenium (Se), offers significant advantages for potassium (K) ion storage due to its comparable theoretical volumetric capacity (2619 mAh cm−3) and higher electronic conductivity (∼102 S m−1), which promotes rapid charge transfer and improves reaction kinetics.
