In this research Au nanoparticles, supported on FeO@polyaniline as a magnetic nanocatalyst, was synthesized and its performance has been evaluated to reduce Methylene Blue (MB) and Methyl Orange (MO) from aqueous solutions. Gold nanoparticles, as a nanocatalyst with excellent activity, were prepared through the reduction of Au using a wild herbal extract (Allium Sp) without any toxic chemical compounds and harmful materials. The synthesized FeO@PANI-Au magnetic nanocatalyst was characterized by different instruments. To investigate the effect of nanocatalyst concentration on the degradation rate of azo dyes, two different catalyst concentrations were used at ambient temperature. According to the carried out calculations, degradation reaction of azo dyes with NaBH in presence of the nanocatalyst is 10 to 10 times faster than degradation without using the catalyst.
在这项研究中，合成了负载在 FeO@聚苯胺上的金纳米粒子作为磁性纳米催化剂，并评估了其还原水溶液中的亚甲基蓝 (MB) 和甲基橙 (MO) 的性能。金纳米粒子作为一种具有优异活性的纳米催化剂，是通过使用野生草本提取物 (葱属) 还原 Au 制备的，没有使用任何有毒化学物质和有害物质。合成的 FeO@PANI-Au 磁性纳米催化剂通过不同的仪器进行了表征。为了研究纳米催化剂浓度对偶氮染料降解率的影响，在室温下使用了两种不同的催化剂浓度。根据进行的计算，在纳米催化剂存在下，硼氢化钠还原偶氮染料的反应速度比没有使用催化剂时快 10 到 10 倍。
