Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Transition metal‐based amorphous/crystalline (a/c) heterostructured catalysts have garnered significant attention due to their exceptional activity, stability, and cost‐effectiveness. However, the precise synergistic regulation of interfacial composition and phase states remains challenging.

Gongye shui chuli, 1985 由于离子交换树脂对各种反离子的吸取具有选择性,所以当两种离子达到离子交换平衡时,它们在水溶液中的浓度比和在树脂相中的浓度比是不一样的。离子交换平衡就是研究平衡时这些离子浓度的关系。

Gongye shui chuli, 1985 离子交换水处理工艺是锅炉给水处理普遍应用的方法。离子交换器是离子交换水处理的主体设备,由于运行中的介质—酸、碱、盐等液体的腐蚀性以及树脂交换剂本身需防止污染的要求,交换器必须坚固。

Gongye shui chuli, 1981 <正>水的离子交换除盐系统，在离子交换床运行失效后要用酸和碱对阳床和阴床进行再生。沧州化肥厂地处盐碱地区，地下井水含盐量高达860亳克/立升，原水在离子交换除盐前，虽经石灰混凝和电渗析予处理，但进入离子交换器前原水中的含盐量仍有500毫克/立升左右，这样就使离子交换床负担过重，周期制水最仅700～800吨,再生频繁。

武陵山地植烟土壤酸度特征及影响因素——以湖南省湘西自治州为例
Shuitu Baochi Xuebao, 2018 为了解多年种植烤烟的山地土壤酸度特征，研究了湘西自治州的土壤酸度指标特征及其关系以及植烟年限和土壤类型、有机质、黏粒对土壤酸度的影响。结果表明：（1）植烟年限对土壤酸度的影响大于土壤类型；随植烟年限增加，土壤pH下降，潜性酸度增加，黄棕壤土的交换性盐基、阳离子交换量和盐基饱和度下降。（2）土壤pH与交换性酸为幂函数关系，交换性铝是土壤交换性酸的主体，土壤交换性酸强度随交换性铝及其相对比例的增加而增加。（3）土壤pH与交换性盐基、阳离子交换量、盐基饱和度为二次曲线关系，当pH6时，随土壤pH增加 ...
