Abstract

The extracted ash from common water reeds locally available in Iraq was used as a cost-effective silica source for single-step synthesis of a heterojunction photocatalyst (Ag2O@CRA) combining 9.75 % Ag2O and a surface area of 99.849 m2/g. The Ag2O@CRA photocatalyst was used to investigate methylene blue (MB) degradation which was eliminated at an initial MB concentration of 20 mg/L, Ag2O@CRA dose of 0.1g/100 mL, pH of 7 after 60 min at visible light. This photocatalyst displayed excellent stability after five cycles with more than 91 % removal of MB dye. The OH was the main radical involved in the MB degradation.

利用可回收 Ag2O@CRA 异质结光催化剂光催化氧化去除废水中的有机污染物
从伊拉克当地常见的水芦苇中提取的灰烬被用作一种具有成本效益的硅源,用于一步合成一种异质结光催化剂(Ag2O@CRA),其中含有 9.75 % 的 Ag2O,表面积为 99.849 m2/g。Ag2O@CRA 光催化剂被用于研究亚甲基蓝(MB)的降解,当亚甲基蓝的初始浓度为 20 mg/L,Ag2O@CRA 的剂量为 0.1g/100 mL,pH 值为 7 时,在可见光下 60 分钟后,亚甲基蓝被消除。这种光催化剂在五个周期后显示出卓越的稳定性,对甲基溴染料的去除率超过 91%。⦁OH是参与甲基溴降解的主要自由基。
