Ion conductive membranes (ICMs) with highly conductive proton selectivity are of significant importance and greatly desired for energy storage devices. However, it is extremely challenging to construct fast proton-selective transport channels in ICMs. Herein, a membrane with highly conductive proton selectivity was fabricated by incorporating porous carbon sieving nanospheres with a hollow structure (HCSNs) in a polymer matrix. Due to the precise ion sieving ability of the microporous carbon shells and the fast proton transport through their accessible internal cavities, this advanced membrane presented a proton conductivity (0.084 S·cm−1) superior to those of a commercial Nafion 212 (N212) membrane (0.033 S·cm−1) and a pure polymer membrane (0.049 S·cm−1). The corresponding proton selectivity of the membrane (6.68 × 105 S·min·cm−3) was found to be enhanced by about 5.9-fold and 4.3-fold, respectively, compared with those of the N212 membrane (1.13 × 105 S·min·cm−3) and the pure membrane (1.56 × 105 S·min·cm−3). Low-field nuclear magnetic resonance (LF-NMR) clearly revealed the fast proton-selective transport channels enabled by the HCSNs in the polymeric membrane. The proposed membrane exhibited an outstanding energy efficiency (EE) of 84% and long-term stability over 1400 cycles with a 0.065% capacity decay per cycle at 120 mA·cm−2 in a typical vanadium flow battery (VFB) system.

研究4种十二取代叔胺(DRN,DEN,DPN和DBN)对高岭石的浮选行为。发现4种叔胺对高岭石的浮选捕收能力都较好,其中DEN最好,浮选回收率最高可达92 %以上。4种叔胺主要依靠静电引力吸附在高岭石表面,在酸性pH范围内,浮选高岭石的回收率较高,随着pH的增大,叔胺的阳离子组分减少,使得浮选回收率下降。Zeta电位研究表明,高岭石在整个pH范围内,表面主要带负电,4种叔胺与高岭石作用后,能显著增加高岭石的Zeta电位。红外光谱研究表面,4种叔胺主要与高岭石表面发生了电性作用的物理吸附。叔胺中N原子上的取代基的给电子效应和空间位阻效应是造成 4 种叔胺浮选能力差异的主要原因。
