Metal-organic frameworks (UiO-66) functionalized glass fiber separator was constructed to accelerate the transport of charge carriers and provide a uniform electric field distribution on the surface of zinc anode.
-
Zinc anode demonstrates preferential orientation of (002) plane under the control of UiO-66-GF, which effectively inhibits dendrites.
-
Density functional theory calculation confirms that the adsorption effect of (002) plane on H is weaker, thus improving corrosion resistance and suppressing the hydrogen evolution reaction.
-
Symmetric cells exhibit highly reversible plating/stripping behavior with long cycle life over 1650 h and full cells demonstrate excellent long-term stability (85%) for 1000 cycles.

构建金属有机骨架 (UiO-66) 功能化玻璃纤维隔膜以加速电荷载流子的传输并在锌阳极表面提供均匀的电场分布。
-
锌阳极在 UiO-66-GF 的控制下表现出 (002) 面的择优取向,有效地抑制了枝晶。
-
密度泛函理论计算证实,(002)面对H的吸附作用较弱,从而提高了耐腐蚀性,抑制了析氢反应。
