This study demonstrates a clean, non-toxic and environment friendly synthetic strategy for the preparation of the Natrolite zeolite/Cu nanoparticles (NPs) using Natrolite zeolite as a natural support and flowers aqueous extract as a reducing and stabilising agent for the synthesis of Cu NPs. Cu NPs with 20 nm diameter were immobilised homogeneously on the surface of Natrolite zeolite. The synthesised Natrolite zeolite/Cu NPs was used as an environmentally benign catalyst for the reduction of 4-nitrophenol, congo red and methylene blue in aqueous media at an ambient temperature. It has been found that the catalyst can be reused several times without any decrease in activity.
本研究展示了一种清洁、无毒且环境友好的合成策略，该策略以钠沸石作为天然载体，花朵水提取物作为铜纳米颗粒（NPs）合成的还原剂和稳定剂，用于制备钠沸石/铜纳米颗粒。直径为20 nm的铜纳米颗粒均匀地固定在钠沸石表面。合成的钠沸石/铜纳米颗粒在环境温度下用作水介质中4-硝基苯酚、刚果红和亚甲基蓝还原反应的环境友好型催化剂。已发现该催化剂可重复使用多次而活性无任何降低。
