ZIF-8HydrostabilityHydrolysis mechanismRecent studies have shown that zeolitic imidazolate framework-8 (ZIF-8) crystallites are not stable in aqueous solution under ambient conditions. When immersed in water, ZIF-8 crystallites are hydrolyzed to zinc and imidazolate ions, which can be condensed to ...
热解ZIF-8温度通常在800 ℃以上,在此温度下大部分Zn会降至零价状态并蒸发。 ZIF-8合成时Zn2+节点可以被其他过渡金属阳离子取代,从而成为合成M-N-C类卟啉材料的理想前驱体。 然而,ZIF-8前驱体在热解过程中如何形成类卟啉单金属位点仍...
