|a Developing materials capable of rapidly decontaminating nerve and blister agents directly under ambient conditions are crucial for practical applications. In this work, Mg3Al1- xZrx-LDH with different Zr4+ doping contents and corresponding OH- intercalated materials Mg3Al1- xZrx-LDH-OH are synthesized. First, they are used for the decontamination of nerve agents under ambient conditions, showing that increasing the Zr4+ doping amount accelerates the decontamination rate of diethyl cyanophosphonate (DECP) and soman (GD), with the half-life of DECP and GD being 3-5 times shorter with Mg3Al0.6Zr0.4-LDH (the highest Zr4+ doping content) compared to Mg3Al1-LDH. Notably, the intercalation of OH- in Mg3Al0.6Zr0.4-LDH further greatly enhances the catalytic activity for DECP and GD, the reaction half-life of DECP and GD with Mg3Al0.6Zr0.4-LDH-OH being 18 s and <15 s, respectively, which is the shortest recorded so far. Additionally, under ambient conditions, Mg3Al0.6Zr0.4-LDH-OH exhibits superior detoxification performance for mustard gas (HD) compared to Mg3Al0.6Zr0.4-LDH, with 92.8% of HD being removed within 6 h. Mechanistic studies reveal that Mg3Al0.6Zr0.4-LDH-OH efficiently decontaminates nerve and blister agents utilizing the synergistic effect of Lewis acid-base sites (Zr4+ and laminate OH groups) and interlayer OH-. To extend the practical applications of the materials, PVA(PAN/LDH-OH) self-detoxifying fiber loaded with Mg3Al0.6Zr0.4-LDH-OH is prepared
