Air sensitive copper nanoparticles have been stabilized using a water soluble aminoclay matrix. The aminoclay shows remarkable permselective behaviour allowing only the ionic species to diffuse through it and react with copper nanoparticles. It blocks the neutral molecule oxygen, thereby stabilizing the copper nanoparticles against oxidation for a longer period.
采用水溶性氨基粘土作为稳定剂制备了对空气敏感的铜纳米粒子。该氨基粘土具有显著的选择渗透性,只允许离子物种通过并与铜纳米粒子反应。它阻止了中性分子氧的扩散,从而使铜纳米粒子更长时间地稳定,防止其氧化。
