, 2013 为开发出一种适用于太阳能吸附制冷的高性能吸附剂,利用浸泡的方法制作了硅胶/氯化钙复合吸附剂,并对吸附剂的吸附性能进行了实验测试。结果表明:与硅胶相比,复合吸附剂不论是吸附量还是吸附速率都有大幅度提高,在相对湿度20%,吸附20min时,硅胶的吸附量为1.96g/100g吸附剂,而复合吸附剂的吸附量为8.08g/100g吸附剂。用制备的复合吸附剂制作一台小型吸附制冷机并进行测试,当热源温度为90°C,冷却水温度为35°C时,在整个循环周期内(15min),制冷功率为1.03kW,单位质量吸附剂的制冷功率 ...

, 2018 固化吸附剂是提高吸附剂传热性能的重要方式,但是恶化了吸附剂的传质性能。以羧甲基纤维素（CMC）为黏结剂的多孔固化吸附剂利用CMC部分分解,在层间产生丰富的孔道,降低了吸附剂的传质阻力,具有强化吸附剂传质作用。本文对多孔硅胶固化吸附剂开展了容量法吸附性能评价、压汞法测试以及吸附性能计算,结果表明,多孔固化吸附剂层内存在一定量的大孔,改善了吸附剂传质特性;根据细孔扩散和表面扩散的计算方法 ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Defect engineering plays a crucial role in regulating the active sites and reaction pathways of nanozymes. In this work, oxygen vacancies (Vo) were successfully introduced and stably regulated in ternary CoFeMo layered double hydroxide (CFM LDHs) via a microwave‐assisted hydrothermal strategy, leading to the construction of oxygen‐vacancy‐rich

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Vanadium redox flow batteries show considerable promise for energy storage, yet their overall performance is still hindered by the limited electrochemical activity of graphite felt (GF) electrodes. Herein, using folic acid and metal salts as precursors, M–N–C functionalized carbon nanosheets (M–NC, M=Co, Fe, and Ni) were prepared via a ...

, 2000 固体吸附制冷是利用低温热源的一种新型制冷方式。本文对多种固体吸附制冷工质对进行了试验研究，得到不同温度下的吸附曲线和解吸曲线，并根据D-A方程进行了线性拟合得到各工质对的W_0、D值。通过分析和比较，在所选工质对中，活性炭纤维-甲醇的吸附解吸综合性能最好，粉末活性炭的性能也较好，但要求的解吸温度较高。乙醇代替甲醇作制冷剂是可行的，但甲醇-乙醇混合物作制冷剂是不可行的。本研究还设计了一种新型太阳能制冷-热水两用机，采用活性炭粉末-甲醇为工质对，两个吸附器，每个吸附器内装4kg活性炭粉末 ...

Gongye shui chuli, 2017 制备了羧甲基纤维素-单宁基吸附树脂，并研究了吸附树脂对亚甲基蓝的吸附性能。羧甲基纤维素与单宁结合，通过羧甲基纤维素羧基与单宁酚羟基的协同作用，能有效提高吸附树脂对亚甲基蓝的吸附性能，最大吸附容量可达1 300 mg/g。在亚甲基蓝溶液初始质量浓度为1 000 mg/L，吸附剂投加质量浓度为1.5 g/L时，吸附树脂对亚甲基蓝的吸附率可达98%以上，且羧甲基纤维素-单宁基吸附树脂具有较好的重复使用性能。

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Capacitive deionization (CDI) using activated carbon (AC) electrodes holds great promise for seawater desalination, yet its practical application is severely constrained by the intrinsic hydrophobicity of carbon surfaces. Herein, we propose a solid‐state superhydrophilic modulation strategy that physically wet‐mixes superhydrophilic MOF ...
