Smart textiles consisting of cotton, Cu-BTC MOF and oxidized graphitic carbon nitride, g-C3N4-ox, nanospheres were synthesized and tested as nerve agent detoxification media and colorimetric detectors. Combining Cu-BTC and g-C3N4-ox resulted in a nanocomposite (MOFgCNox) of heterogeneous porosity and chemistry. Upon the deposition of MOFgCNox onto cotton textiles, a stable fabric with a supreme photocatalytic detoxification ability towards the nerve gas surrogate, dimethyl chlorophosphate, was obtained. The detoxification process was accompanied by a visible and gradual color change, which can be used for the selective detection of chemical warfare agents and for monitoring their penetration inside a protective layer. These smart textiles adsorbed almost 7 g of CWA surrogate/its detoxification products per gram of Cu. The superior performance was linked to the high dispersion of the MOF crystals on the fibers, and a specific texture promoting the availability of the active copper centers.

MOF / gC 3 N 4纳米球的智能纺织品,用于化学战剂的快速检测/解毒

合成了由棉,Cu-BTC MOF和氧化石墨氮化碳,gC 3 N 4 -ox,纳米球组成的智能纺织品,并作为神经毒剂解毒介质和比色检测器进行了测试。结合Cu-BTC和gC 3 N 4-ox产生了具有不同孔隙率和化学性质的纳米复合材料(MOFgCNox)。将MOFgCNox沉积到棉纺织品上后,获得了一种对神经气体替代物氯代磷酸二甲酯具有最高光催化解毒能力的稳定织物。排毒过程伴随着可见的逐渐变色,可用于选择性检测化学战剂并监测其在保护层内部的渗透。这些智能纺织品每克铜吸附近7克CWA替代品/其排毒产品。优异的性能与MOF晶体在纤维上的高度分散以及特定的质地可促进活性铜中心的可用性有关。
