A method for reducing odor is provided. In one embodiment, the method comprises forming a coordination complex between particles having a positive zeta potential and a transition metal. The method further comprises contacting the coordination complex with an odorous compound, the transition metal providing one or more active sites for capturing the odorous compound. For example, in one embodiment, the particles are formed from alumina-coated silica. In addition, the coordination complex may be formed using a bifunctional chelating agent.
本文提供了一种减少气味的方法。在一个实施方案中,该方法包括在具有正 zeta 电位的颗粒和过渡金属之间形成配位络合物。该方法还包括将配位复合物与有气味的化合物接触,过渡金属提供一个或多个活性位点以捕捉有气味的化合物。例如,在一个实施方案中,颗粒由氧化铝包覆的二氧化硅形成。此外,还可以使用双功能螯合剂形成配位络合物。
